    StellarNet spectrometers are portable & compact fiber optic instruments for UV, VIS, and NIR measurements in the nm range. The StellarNet series of miniature spectrometers is a step up in low cost instrument design, offering CCD & PDA / detectors. The units are engineered to have no moving parts, no detector sockets, ruggedized aluminum enclosure, and an integrated A/D. iHR Imaging Spectrometer. The iHR spectrometer offers a unique combination of spectral quality, flexibility, robustness, and ease of use that makes it the ideal general-purpose spectrometer for performing spectral measurements with quality a focal length of m, the iHR is designed to deliver superb image quality for spectral measurements, and offers the ability to.

    This image of the northern wall of Coprates Chasma, in Valles Marineris, was taken by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) at UTC ( a.m. EDT) on J , near degrees south latitude, degrees east longitude.   2. Overall instrument design of the imaging Fourier transform spectrometer. Figure 1 shows the schematic layout of the depth-resolved hyperspectral imaging spectrometer. Three diode-pumped solid states lasers (CNI laser) with emission wavelength of nm, nm and nm respectively were used as light sources, which can excite broad range of fluorophores.

    A mass spectrometer is an analytical instrument that is used to identify the amount and type of chemicals present in a sample by measuring the mass-to-charge ratio and abundance of gas-phase ions.. Time-of-flight spectrometer. The energy spectrum of particles of known mass can also be measured by determining the time of flight between two detectors (and hence, the velocity) in a time-of-flight. But one of the most fundamental divisions is between imaging and nonimaging spectrometers. If you're analyzing a uniform sample or looking at the spectral properties of a single light source, then nonimaging is fine. But if you need to get spectral details for every point across a scene or a medical specimen, then you need an imaging spectrometer.

photon emissions will be induced. These emissions will occur to some degree throughout the UV-visible-IR spectrum. The emissions arise from a combination of processes including gas phase collisions between relatively energetic ambient and surface Author: D.

Torr and Marsha R. Torr. The high spectral resolution of imaging spectrometer systems creates the opportunity to identify some materials by their absorption-band characteristics. For single absorption bands, the parameters of depth, width, and position can be defined (Fig.

).The existence of an absorption band at a particular wavelength can be declared whenever the depth exceeds a certain threshold (Rubin. [7] The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) is a hyperspectral imager with a spatial resolution of 15–19 m/pixel and a spectral range of – nm with a spectral sampling of nm and a spectral resolution in the infrared (∼ nm) of about 15 nm [Murchie et al., ].

Gimbals allow off‐nadir pointing in Cited by: emission levels near Space Station should be monitored on a routine basis.

We have developed a small imaging spectrometer which can be readily accommodated for the purpose of measuring induced spectral contamination over a wavelength range extending from the ultraviolet to.

An imaging spectrometer is an instrument used in hyperspectral imaging and imaging spectroscopy to acquire a spectrally-resolved image of an object or scene, often referred to as a datacube due to the three-dimensional representation of the data.

Two axes of the image corresponds to vertical and horizontal distance and the third to principle of operation is the same as that of. Compact Imaging has developed and patented a miniature optical sensor technology called MRO for the rapidly growing biometric security and mobile health monitoring markets.

+ [email protected] Furthermore, the detector/collection system size, weight, and cost also can be reduced by ~10 times by employing a NCT-CCD spectrometer. The results have the potential in realizing a compact and low-cost LIBS system for the rapid identification of plastics with higher accuracies for the real-time application.

Solar induced fluorescence (SIF) is an ecological variable of interest to remote sensing retrievals, as it is directly related to vegetation composition and condition. FIREFLY (fluorescence imaging of red and far-red light yield) is a high performance spectrometer for estimating SIF.

FIREFLY was flown in conjunction with NASA Goddard’s lidar, hyperspectral, and thermal (G-LiHT. An image slicing spectrometer (ISS) for microscopy applications is presented. Its principle is based on the redirecting of image zones by specially organized thin mirrors within a custom fabricated component termed an image demonstrated prototype can simultaneously acquire a nm spectral range within its 2D field of view from a single image.

The feasibility of a compact Fourier-Transform-Imaging-Spectrometer (FTIS) for small satellite remote sensing missions is currently being studied under ESA contract. Compared to classical hyperspectral imagers using dispersive spectrometers the major advantages of the FTIS is the compact optics module and the tolerable higher detector.

This shows the first site on Mars imaged by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) using its full-resolution hyperspectral capability, with a "targeted image." During a targeted image, CRISM's movable gimbal tracks a point on the surface, and slowly scans across it.

A key update to the VSWIR imaging spectrometer occurred at the request of NASA in the timeframe.
