Abstract:

As portable spectrometers have been developed, the research of spectral analysis has evolved from a traditional laboratory-based closed environment to a network-connected open environment. Consequently, its application areas are expanding in combination with machine learning techniques. The device-to-device variation in the spectral response of portable spectrometers is a critical issue in a machine learning-based service scenario since the classification performance is highly dependent on the consistency of spectral responses from each spectrometer. To minimize device-to-device variation, a cuboid prism is employed instead of a combination of mirrors and prism to construct an optical system for the spectrometer. The spectral responses are calibrated to correct pixel shift on the image sensor. Experimental results show that the proposed method can minimize the device-to-device variation in spectral response of portable spectrometers.

Abstract:

Electron energy loss (EEL) microanalysis is a powerful technique for studying the chemical composition of a specimen and the distribution of each constituent. The energy loss spectrum of the post-specimen electron beam, on which the technique is based, is obtained by the use of an energy spectrometer. In transmission electron microscopy, the most prevalent type of imaging energy spectrometer is the Prism-Mirror-Prism (PMP) design (Fig. 1). It is compact in size and easy to align. For an acceptance half angle (β in Fig. 1) of 10 mradian, which corresponds to the full field of view of a modified Siemens 102 microscope of our laboratory, an experimental PMP spectrometer with a straight-faced magnetic prism has an energy resolution of 25 eV at the microscope operating voltage of 80 kV. This resolution has permitted ionization energies of different elements to be resolved, thus making the elemental microanalysis possible. However, a resolution of 25 eV is inadequate for resolving and possibly imaging with characteristic molecular energy losses, that are located in the 1.5-10 eV region of the electron energy loss spectrum.

Abstract:

One of the main applications of an energy filter is to obtain elemental distribution images by electron spectroscopic imaging. This technique has been pushed to the imaging of fine structure such as the sp2 and sp3 states of carbon at a sub-nanometer spatial resolution. However, low energy loss imaging in the region of the molecular excitations has largely remained unexplored due to the limitation in the energy resolution obtainable in the energy filters. Molecular absorptions in the visible and UV regions of the spectrum occur at 1.5 eV to 10 eV. Thus it would be necessary to have an energy resolution of about 1 eV or better.An optimized Prism-Mirror-Prism energy filter has been built by altering the straight faced pole pieces to circular curvatures. See Figure 1. The optimum curvatures for each of the faces were determined iteratively. In order to simulate the electron path accurately through the Prism-Mirror-Prism filter, it was necessary to calculate the magnetic fringing fields using the Boundary Element Method as outlined by Kasper. The ray-tracing procedure indicated a theoretical energy resolution of 1.3 eV for the optimized magnetic prism. This has been tested on our prototype spectrometer currently installed in the Siemens EM 102. An energy resolution of 1.1 eV was obtained.

Abstract:

Energy filtered transmission electron microscopy has the potential to provide high resolution, spatially resolved, atomic and chemical information. However, aberrations generated by the electron spectrometer blur the energy resolution and limit the atomic or molecular distributions that can be studied. Energy absorptions corresponding to the visible light range fall below an energy loss of 5 eV. The selection of electrons that have lost an amount of energy corresponding to chromophore absorption by the sample thus requires a spectrometer with a high energy resolution over the full image plane. A corrected prism-mirror-prism filter that has a resolution of 1.1 eV, sufficient to select these low energy loss electrons, was developed and installed by us in a Zeiss EM902. Its imaging capability was verified for a number of different chromophores. The chromophore currently under study is that of the green fluorescent protein (GFP).

Abstract:

A new version of the photodiode array Fourier transform spectrometer for visible spectroscopy is described. In this version, a birefringent interferometer with a Wollaston prism produces a spatial interferogram of the radiation, which is detected by a linear photodiode array. In addition to the merit of having no mechanical moving parts, this spectrometer has the beneficial advantage of the simple and rugged optical setup and alignment due to its common-path and in-line interferometer formation. These advantages lend this spectrometer to field-use applications. Emission spectra of a low-pressure mercury lamp and a light-emitting diode and an absorption spectrum of a didymium glass filter measured by the developed spectrometer are presented.

Abstract:

A simulation method for acquiring spectrometer’s Spectral Response Function (SRF) based on Huygens Point Spread Function (PSF) is suggested. Taking into account the effects of optical aberrations and diffraction, the method can obtain the fine SRF curve and corresponding spectral bandwidth at any nominal wavelength as early as in the design phase. A prism monochromator is proposed for illustrating the simulation procedure. For comparison, a geometrical ray-tracing method is also provided, with bandwidth deviations varying from 5% at 250 nm to 25% at 2400 nm. Further comparison with reported experiments shows that the areas of the SRF profiles agree to about 1%. However, the weak scattered background light on the level of 10−4 to 10−5 observed by experiment could not be covered by this simulation. This simulation method is a useful tool for forecasting the performance of an underdesigned spectrometer.

Abstract:

Serial detection systems that are standardly employed in electron energy loss spectrometry (EELS) only examine one energy channel at a time and are therefore inherently inefficient. Parallel detection systems using either photodiode arrays or charge-coupled devices (CCDs) promise to remove this inefficiency. However, to completely replace the serial detection systems, they will need 1) a detective quantum efficiency (DQE) approaching 100%, 2) a dynamic range sufficient to cover the range of intensities encountered in the energy loss spectra (about 106), and 3) ability to operate without any loss in energy resolution.We have constructed and tested a parallel detection system which incorporates three quadrupole lenses placed after the magnetic sector prism of the Gatan 607 spectrometer, a single crystal YAG scintillator, and a fiber-optically coupled linear photodiode array. The quadrupoles magnify the small dispersion (1.8μm per eV at 100kV primary voltage) of the spectrum produced by the magnetic sector to as high as 1 mm per eV without producing any spectrum rotation and with small power requirements.

Abstract:

An imaging spectrometer instrument based on a prism-grating-prism (PGP) element as the dispersive component and advanced camera solutions for on-line applications are presented. The PGP element uses a volume type holographic plane transmission grating made of dichromated gelatin (DCG). Currently, spectrographs have been realized for the 400–1050 nm region but applicable spectral region of the PGP is 380–1800 nm. Spectral resolution is typically between 1.5 and 5 nm. The on-axis optical configuration and simple rugged tubular optomechanical construction of the spectrograph provides a good image quality and resistance to harsh environmental conditions. Spectrograph optics are designed to be interfaced to any standard CCD camera. Special camera structures and operating modes can be used for applications requiring on-line data interpretation and process control.

Abstract:

Abstract. We illustrate the utility of variational destriping for ocean color images from both multispectral and hyperspectral sensors. In particular, we examine data from a filter spectrometer, the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi National Polar Partnership (NPP) orbiter, and an airborne grating spectrometer, the Jet Population Laboratory's (JPL) hyperspectral Portable Remote Imaging Spectrometer (PRISM) sensor. We solve the destriping problem using a variational regularization method by giving weights spatially to preserve the other features of the image during the destriping process. The target functional penalizes the neighborhood of stripes (strictly, directionally uniform features) while promoting data fidelity, and the functional is minimized by solving the Euler–Lagrange equations with an explicit finite-difference scheme. We show the accuracy of our method from a benchmark data set which represents the sea surface temperature off the coast of Oregon, USA. Technical details, such as how to impose continuity across data gaps using inpainting, are also described.

Abstract:

UV–visible absorption spectroscopy is useful for probing the electronic and structural changes of protein active sites, and thus the on-line combination of X-ray diffraction and spectroscopic analysis is increasingly being applied. Herein, a novel absorption spectrometer was developed at SPring-8 BL26B2 with a nearly on-axis geometry between the X-ray and optical axes. A small prism mirror was placed near the X-ray beamstop to pass the light only 2° off the X-ray beam, enabling spectroscopic analysis of the X-ray-exposed volume of a crystal during X-ray diffraction data collection. The spectrometer was applied to NO reductase, a heme enzyme that catalyzes NO reduction to N2O. Radiation damage to the heme was monitored in real time during X-ray irradiation by evaluating the absorption spectral changes. Moreover, NO binding to the heme was probedviacaged NO photolysis with UV light, demonstrating the extended capability of the spectrometer for intermediate analysis.
