Abstract:
Abstract This paper presents results of a study of some of the characteristics of a PDR-1 digital strong-motion accelerograph. Results are presented for laboratory tests of the background noise level of the instrument, and these results are compared with previously reported observations for optical instruments. Noise levels for the digital instrument are found to be one or two orders of magnitude lower than for an analog optimal instrument. The paper discusses determination of displacement from acceleration data, and results of laboratory tests are presented. An instrument anomaly in the FBA-13 transducer is identified, a simple data correction algorithm proposed, and examples given. The paper also presents detailed results of a comparison of earthquake records obtained from side-by-side digital and optical analog instruments during an aftershock of the 1983 Coalinga earthquake.

Abstract:
Using virtual instrument technology, digital signal processing technology and traditional optical radiation measuring technology to construct optical radiation measuring system breaks the construction methods of traditional instruments. Signal processing, collection, control and process of measuring system are implemented by the software LabVIEW8.2. And they are integrated in a computer. The computer not only is data processing center, but also is instrument control center. While measuring, the user uses the mouse to operate the handles including knobs, switch and buttons of virtual instrument panel to select instrument functions and set various parameters, which realizes measuring optical radiation with different wave bands and different intensity. And the user can change instrument operation panel, modify system software, transform instrument function, and customize instrument parameters, which embodies the idea that the software is the instrument.

Abstract:
This paper explores the role of instrument engineering parameters in master–slave optical differences. Engineering parameters with significant ( p = 0.05) impact were classified into three groups according to the magnitude of their influence (analysis of variance mean squares) on optical differences. The only parameter with high influence was preamplifier gain. Filter area, filter bandwidth, detector temperature, idle filter wheel temperature, sample temperature and optics unit differences exerted medium impact. There were seven properties with low but still significant impact. Software was developed to aid users and manufacturers in selecting optical standardisation and in diagnosing instrument differences.

Abstract:
High-performance megapixel focal plane arrays with small pixels have been widely used in modern optical remote sensing, astronomical, and surveillance instruments. In the prediction models applied in the traditional instrument performance analysis, the image of a point source is assumed to fall on the center of a detector pixel. A geometrical image of a point source in the realistic optical system may actually fall on any position on the detector pixel because the sensor’s line of sight includes pointing errors and jitter. This traditional assumption may lead to an optimistic error, estimated at between 10% and 20%. We present the critical factors that impact the performance estimate in a realistic instrument design based on the prediction for the noise-equivalent power (NEP). They are the optical centroid efficiency (OCE) and the ensquared energy, or more precisely, the energy on the rectangular detector pixel (EOD). We performed the simulation studies for imaging with an optical system with and without a generalized rectangular central obscuration.

Abstract:
Objective. Motion analysis of surgical instruments can be used to evaluate laparoscopic surgical skills, and this study assessed the validity of an optical tracking system for the assessment of laparoscopic surgical motor skills. Methods. Ten experienced surgeons and ten novices were recruited to complete the transferring tasks on a laparoscopic simulator. An optical tracking system, Micron Tracker, was used to capture the marker points on each instrument and to obtain the coordinates of the marker points and the corresponding instrument tip coordinates. The data are processed to create a coordinate system based on the laparoscopic simulator and to calculate the movement parameters of the instruments, such as operating time, path length, speed, acceleration, and smoothness. At the same time, the range of motion of the instrument (insertion depth and pivoting angle) is also calculated. Results. The position that the tip of the instrument can reach is a small, irregularly shaped spatial area. Significant differences ( p < 0.05 ) were found between the surgeon and novice groups in parameters such as operating time, path length, mean speed, mean acceleration, and mean smoothness. The range of insertion depth of the instruments was approximately 150 mm to 240 mm, and the pivoting angles of the left and right instruments were 30.9° and 46.6° up and down and 28.0° and 35.0° left and right, respectively. Conclusions. The optical tracking system was effective in subjectively evaluating laparoscopic surgical skills, with significant differences between the surgeon and novice groups in terms of movement parameters, but not in terms of range of motion.

Full text
Abstract:
Abstract. Active long-path differential optical absorption spectroscopy (LP-DOAS) has been an effective tool for measuring atmospheric trace gases for several decades. However, instruments were large, heavy and power-inefficient, making their application to remote environments extremely challenging. Recent developments in fibre-coupling telescope technology and the availability of ultraviolet light emitting diodes (UV-LEDS) have now allowed us to design and construct a lightweight, portable, low-power LP-DOAS instrument for use at remote locations and specifically for measuring degassing from active volcanic systems. The LP-DOAS was used to measure sulfur dioxide (SO2) emissions from La Fossa crater, Vulcano, Italy, where column densities of up to 1.2 × 1018 molec cm−2 (~ 500 ppmm) were detected along open paths of up to 400 m in total length. The instrument's SO2 detection limit was determined to be 2 × 1016 molec cm−2 (~ 8 ppmm), thereby making quantitative detection of even trace amounts of SO2 possible. The instrument is capable of measuring other volcanic volatile species as well. Though the spectral evaluation of the recorded data showed that chlorine monoxide (ClO) and carbon disulfide (CS2) were both below the instrument's detection limits during the experiment, the upper limits for the X / SO2 ratio (X = ClO, CS2) could be derived, and yielded 2 × 10−3 and 0.1, respectively. The robust design and versatility of the instrument make it a promising tool for monitoring of volcanic degassing and understanding processes in a range of volcanic systems.

Full text
Abstract:
MAORY will be the multi-conjugate adaptive optics module for the ELT first light. Its main goal is to feed the high-resolution NIR imager and spectrograph MICADO. The present Thesis address the MAORY system at the level of optical design and analysis. MAORY is a complex science projects whose stakeholder is the scientific community. Its requirements are driven by the science cases which request high resolution and astrometric accuracy. In an ideal world without atmospheric turbulence, MAORY optics must deliver diffraction-limited images with very low optical distortions. The tolerance process is one of the most important step in the instrument design since it is intended to ensure that MAORY requested performances are satisfied when the final assembled instrument is operative. The baseline is to operate wavefront sensing using six sodium Laser Guide Stars and three Natural Guide Stars to solve intrinsic limitations of artificial sources and to mitigate the impact of the sodium layer structure and variability. The implementation of a laboratory Prototype for Laser Guide Star wavefront sensor at the beginning of the phase study of MAORY has been indispensable to consolidate the choice of the baseline of wavefront sensing technique. The first part of this Thesis describes the results obtained with the Prototype for Laser Guide Star wavefront sensor under different working conditions. The second part describes the logic behind the tolerance analysis at the level of MAORY optical design starting from definition of quantitative figures of merit for requirements and ending with estimation of MAORY performances perturbed by opto-mechanical tolerances. The sensitivity analysis on opto-mechanical tolerance of MAORY is also a crucial step to plan the alignment concept that concludes the arguments addressed by this Thesis.

Full text
Abstract:
A two-color lidar instrument and inversion algorithms have been developed for the study of atmospheric aerosols. The two-color lidar laser transmitter is based on the collinear fundamental 1064 nm and second harmonic 532 nm output of a Nd:YAG laser. Scattered light is collected by the two-color lidar receiver using a Schmidt-Cassegrain telescope with the 532 nm channel monitored using a gated photomultiplier tube (PMT) and the 1064 nm channel monitored using an avalanche photodiode (APD). Data is collected from the PMT and APD using a 14 bit 200 MHz data acquisition card. The lidar inversion algorithm developed to analyze the data collected by the two-color lidar is based on a constant lidar ratio assumption at both the 1064 nm and 532 nm wavelengths with the constrained ratio aerosol model (CRAM) providing the initial lidar ratios at the two wavelengths to complete the lidar inversion. Data from the CALIOP lidar on board the CALIPSO satellite are presented to verify software algorithm performance. Data from the two-color lidar are then presented demonstrating the two-color lidar instrument\'s capabilities. The analysis of these data identifies smoke and industrial aerosols in the atmosphere above Bozeman. Finally an error analysis of the lidar instrument and accompanying analysis software is presented. The findings of this analysis are that error introduced by the APD and PMT is dominant; the error introduced by the optical detectors is much larger than the error from other sources examined such as quantization error, and the error associated the use of numerical integration in the data analysis algorithm.

Abstract:
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2013.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references.<br>Optical coherence tomography (OCT) is a non-contact, high resolution biomedical imaging technique that uses low coherence interferometry to generate cross-sectional images of tissue. OCT has become a standard tool in ophthalmology for imaging the retina to detect or monitor pathologies. Recent research advances in swept source lasers have allowed swept source OCT (SS-OCT) to have 5-50x faster imaging speeds when compared to SD-OCT commercial systems. This thesis describes the design of a handheld SS-OCT instrument to screen for retinal diseases. Many retinal diseases are asymptomatic in their early stages and remain undetected until they advance to cause irreversible vision loss. Early detection and treatment of these diseases can prevent permanent damage to the retina. While OCT has been proven effective at diagnosing retinal pathology, most commercial systems are bulky and table mounted, limiting their screening capabilities. The compact and easy to use handheld device can be used to quickly screen patients outside of the ophthalmology clinic in primary care, pediatrics applications, or in the field in developing countries. A custom motion registration algorithm corrects for the additional operator motion in the images. The wide scanning angle combined with the high imaging speeds used in SS-OCT allows screening of pathology with a single volumetric data set spanning the areas of interest on the retina.<br>by Chen David Lu.<br>S.M.

Abstract:
In space exploration optical imaging is one of the key measurements conducted, with a vast majority of missions heavily relying on optical data acquisition to examine alien worlds. One such endeavor is ESA’s F-class mission Comet Interceptor, a multi-element spacecraft expected to be launched in 2028. It consists of a primary platform and two sub-spacecraft, one of which carrying the Optical Periscopic Imager for Comets (OPIC). An accurate prediction of the generated imagery is of undeniable importance as mission planning and instrument design strongly depend on the real-world output quality of the camera system. In the case of OPIC, the collected image data will be used to reconstruct three dimensional models of targeted celestial bodies. Furthermore, the sub-spacecraft faces a risk of high velocity dust impacts, leading to a limited number of data samples to be broadcasted back to the primary spacecraft before collision. Testing image prioritization algorithms and reconstruction methods prior to mission start requires accurate computer-generated images. Camera sensors and lens systems are subjected to various optical distortions and aberrations that degrade the final image. Popular render engines model those effects to a certain degree only and as a result produce content that is looking too perfect. While more sophisticated software products exist, they often come with compatibility limitations and other drawbacks. This report discusses the most important optical aberrations, as well as their relevance for optical instruments in space applications with a particular focus on the Comet Interceptor mission. The main part of this work is however the implementation of a dedicated software tool that simulates a variety of optical aberrations complementing the basic camera model of the Blender render engine. While its functionality is mostly demonstrated for OPIC, the software is designed with a broad range of usage scenarios in mind.

Abstract:
Australia has been the world leader in astrophotonic developments, led by the SAIL/Astralis-USyd labs at The University of Sydney. A new, novel optical fibre imaging device, called a ‘Hexabundle’ was invented by a team in the SAIL/Astralis-USyd labs and was implemented in an integral field spectrograph instrument called ‘SAMI’ on the Anglo-Australian Telescope (AAT). Based on the success of SAMI, an innovative new $7m instrument called Hector has now been built and is currently being commissioned on the AAT. Hector has new upgraded hexabundles, positioners and spectrographs. It will now tackle a survey of 15,000 galaxies to give a sample that will have the statistical power to disentangle, for the first time, the impact of large-scale structure in the universe on the formation of galaxies. The hexabundles for Hector are larger than for SAMI, with 5 sizes up to 169 optical fibre cores to reach 26 arcsecs on sky, allowing imaging of most of the Hector Galaxy Survey targets out to 2 effective radii. These new hexabundles have regular hexagonal fibre packing to simplify post-processing and maximise the light collection with a higher fill fraction. Hector has 21 new hexabundles. There is significant development involved in these upgraded hexabundles. This thesis focuses on the characterisation and testing of the fibre system for Hector. In particular the throughput and focal ratio degradation (FRD) characterisation was crucial at all stages of the hexabundle development to guide the improvements in the hexabundle process to achieve hexabundles with optical performance as good as bare single fibres. My work in this thesis has been a fundamental contribution to the build and performance of the Hector fibre system. The instrument is now (mid-2022) beginning the Hector Galaxy Survey which will enable the work of > 70 astronomers.

Full text
Abstract:
The work reported in this thesis has been carried out in the following two areas of Optical metrology: 1. Measurement and correction of prism angles 2. Measurement of refractive indices using a spectrograph. The prism angles are conventionally tested by mechanical bevel protractors, autocol-limators (angle dekkors), simple interference techniques and interferometers. All these methods have their own limitations either in accuracy or in terms of cost. Mechanical methods are usually employed to measure the angles of prisms. Interference techniques and interferometers are also used but they need optically polished components. For both mechanical and simple interference methods of testing, it is essential to fabricate more than a single component in number. The process of building interferometers or purchasing interferometers, angle dekkors and standard angle gauges is not cost effective for many research laboratories, and medium scale industries. To overcome these difficulties simple and inexpensive methods without sacrificing the accuracy in the bargain are suggested for the measurement of prism angles, based on the principles of reflection of light. The refractive indices of prism materials for invisible and weaker spectral lines are usually determined from spectrograms using dispersion formulae and numerical interpolation techniques. In these methods, the accuracy of the results depends on the accuracy of determining the constants of the dispersion formulae. A simple experimental technique, using a spectrograph, is devised for the measurement of refractive indices of solids and liquids both for visible and invisible spectral lines (wavelengths). The thesis has been divided into six chapters. The first chapter starts with the general introduction. The second chapter presents the literature review of the existing methods for angle and refractive index measurements. The third chapter describes the proposed new techniques for prism angle measurements. The fourth chapter presents the experimental results of angle measurements, and the discussion of the accuracy of the results. This chapter also gives the scope for further research. The fifth chapter describes a newly proposed technique for measuring refractive indices and the experimental results. This chapter also gives the scope for further research. The summary of the results, conclusions, and suggestions for further work are presented in chapter six.

Abstract:
The Fourier Transform Spectrometer consists of a Michelson interferometer, a source and a detector. The sample is placed between the interferometer and detector. A mirror moving at constant speed creates an optical path difference. The measured signal is called the interferogram. After mathematical treatment, including the Fourier transform, the spectrum is retrieved. This spectrum contains information about the sample, but also on the instrumental response. This spectrum is usually ratioed to an open beam or background spectrum which eliminates the instrumental function. Such an instrument can be constructed for operation in any spectral region, but shorter wavelengths dictate more stringent requirements on the optical parts and motion accuracy. Evidently, suitable detectors and sources must be selected. High-end research grade instruments can be easily be re-configured for operation from 1000μm to 250nm.

Abstract:
Until recently establishing numbers of continuously operating lidar systems to monitor all cloud and aerosol structure of the atmosphere would have meant large manned instruments and would be largely beyond the realm of feasibility. A program is now in progress for such full time atmospheric monitoring. The development of compact, eyesafe, low cost automated lidar systems that we have called Micro Pulse Lidar (MPL) is the enabling factor.1,2 The basis of the MPL instruments is a highly photon efficient design which utilizes advanced solid state components. The first MPL field instrument began operation in 1992 and in 1993 was put into full time use at the Department of Energy’s Atmospheric Radiation Measurement (ARM) program site in Oklahoma. The initial instrument was capable of detecting all clouds and some aerosol structure on a full time basis. An improved instrument was introduced last year which has significantly higher performance and is now at the Oklahoma ARM site. Copies of the instrument are being deployed to five or more field sites around the globe. These instruments will provide a unique view of cloud and aerosol structure for the atmosphere. In this paper we discuss the improvements in the instrument design, the data that the systems are producing and analysis techniques and initial results from the data.

Abstract:
The gradient-index Maxwell fish-eye lens is an example of an absolute instrument, meaning that it stigmatically images a 3-D domain. An additional characteristic of such a system is that the image is an accurate geometrical projection of the object, i.e., there is no distortion. The ray paths inside this gradient-index lens are always sections of circles. A much more common situation is that of an aplanatic surface, which only perfectly images one spherical surface onto another one. This case is much more limited than a Maxwell’s lens, as it cannot perfectly image an extended volume of space; it is therefore not a perfect system. The number of known perfect systems can be counter on two thumbs: variations of the Maxwell lens and a plane mirror. This paper describes a new perfect instrument, which forms a perfect real image, at unit magnification, of a 3-D object volume. It is a single-element catadioptric design, involving one reflection. All orders of all aberrations are zero. In its most useful embodiment, it images one plane surface onto another, perfectly. The Dyson design and the Wynne-Dyson design can be regarded as crude approximations to this new system.
