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-1

Abstract:

In physics learning, visual representation is an important tool for turning abstract concepts into more easily understood ones, especially topics about optical equipment. However, current teaching instruments are often less effective in providing adequate visualization. This research on the development of visual representation test instruments for senior high school or Islamic senior high school (SMA/MA) on optical device topic was carried out with the aims of 1) developing a visual representation test instrument on optical devices material, 2) determining the expert validity of the visual rep

Abstract:

In the context of Physics learning, verbal representation is very important to foster problem solving skills. However, the role of these representations has not been thoroughly measured and supported by good measurement instruments. In addition, the topic of optical instruments has concepts that can be expressed with verbal representations and is one of the important topics in physics. Therefore, in this study, an instrument was developed to measure students' verbal representation ability on optical instrument topic. The objectives of this research are to (1) determine the instrument's constru

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 de

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

Moreover, each equatorial aberration is related to an angle-independent function by a scale transform factor. The principles of the instrument line-profile calculation are general.

Absolute instrument refers to a media that can make light rays to propagate in a closed orbit and perform imaging and self-imaging. In the past few decades, traditional investigations into absolute instrument have been centered on the two-dimensional plane and rotational symmetry situations, and have paid less attention to three-dimensional counterparts. In this article, we design two types of three-dimensional non-spherically symmetric absolute instruments based on conformal inverse transformation, which originated from the three-dimensional Luneburg lens and Lissajous lens. We carry out ray

Abstract:

The Naval Research Laboratory and the US Naval Observatory are building a phase tracking optical interferometer for high resolution imaging and astrometry. This instrument will be a six element interferometer capable of true imaging using interferometric amplitudes and closure phases. This talk will describe the instrument, with an emphasis on those aspects of the array related to high resolution imaging. The status of the project will be presented. First light is planned for October 1993, with 6 element imaging beginning in 1994.

Abstract:

Abstract Molecular contamination is a problem during long term storage of space instruments to be launched later. We investigate laser cleaning of molecular contamination on optical materials aiming to make a first step towards the development of a contactless remote cleaning method that allows the cleaning of critical optical components without disassembling the instrument. A nanosecond laser at 266 nm was used and, depending on the homogeneity of the beam profile, good results were obtained on ZnSe, CaF2 and protected silver mirrors.

Abstract:

The design of a spectrometer for the observation of infrared vibrational circular dichroism (VCD) is reported. This instrument utilizes f/4 aperture, a minimum of optical elements, and a new electronic data acquisition method to improve the sensitivity of previous dispersive units. The instrument described exhibits a level of sensitivity comparable to that of present Fourier transform (FT) VCD instruments, while avoiding some problems which still persist in FT-VCD.
