Book excerpt: "This thesis involved the design and testing of a modular imaging spectrometer instrument (MISI), which can provide hyperspectral image data at a very high ground resolution. The instrument can serve as an airborne laboratory for many remote sensing applications. The optical/mechanical/electrical system was designed using a system engineering approach with emphasis on system and sub-system modulation transfer function (MTF) analysis. Extensive modeling was used to predict the system performance and to aid the design trade process. Many sensor testing methodologies were developed to evaluate the performance of this electro-optical imaging system. The system engineering approach, the modeling tools developed, and the sensor performance testing methods can also be applied to other electro-optical (EO) imaging systems design and testing. Performance evaluation experiments verify that MISI has met its image quality goals. By using finite element analysis and optical image formation theory, the performance of a high-speed scan mirror was modeled. This model was used as a design tool to aid the development of the scan mirror assembly. A model-based algorithm was developed to derive the MTF of the imaging system from its edge spread function. By using prior information about the system, the MTF can be derived from very noisy edge traces. Finally, an alternative EO imaging system design criterion the information criterion, is investigated as a overall image quality measure. The results show that line-scan imaging system can be optimized informationally by shaping the electronic filter response and detector aperture. The analytical results also show that the traditional line-scan imaging system design does not maximize information, and the informationally optimized design with a diamond-shaped aperture can provide up to 1.5 bits more information than the traditional design over a broad range of radiance fields. Computer simulation confirms that by combining image acquisition and image processing, informationally optimized design tends to maximize image fidelity."--Abstract.

Download or read book Design and Development of a Ranging-Imaging Spectrometer written by and published by . This book was released on 2005 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The topic of the dissertation is the design and development of an imaging spectrometer that is capable of simultaneously measuring range. The instrument developed, called the Ranging-Imaging Spectrometer (RIS), is a marriage of two well-established technologies. The technologies are the Computed Tomographic Imaging Spectrometer (CTIS) and the Scannerless Range Imaging Laser Detection and Ranging instrument (SRI LADAR) developed at The University of Arizona and Sandia National Labs respectively. The instrument is the first of it kind with its ability to simultaneously detect passive reflectance spectra and active range detection on a single focal plane array without spatial scanning. This RIS has applications in military reconnaissance, mining, surveying, robotic vision, and autonomous vehicle navigation. The instrument has 77 x 77 pixels of spatial resolution, 61 spectral samples from 597 - 897 nm withDl = 5 nm, and range resolution of 8.92" 1.23 cm. The topic of the dissertation is first motivated by discussing current technologies and their related drawbacks that provide reasons for developing the RIS. A basic review of imaging spectrometry, CTIS, and SRI LADAR are presented as foundations on which the instrument is constructed. Technical data is then presented including: the design of the CTIS components, the opto-mechanical design for mounting and mating the two systems together, the spectral and range calibration techniques, the analysis of the spectral and range resolutions and tests, and a section on range errors and correction techniques. A section detailing range noise suppression techniques using statistics is included along with future work.
Book Synopsis Design of an Offner-Chrisp Imaging Spectrometer for a Planetary Fluorescence Instrument by : Tristan Carlson

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectrometers have been an integral part of space exploration in the late 20th and 21st centuries and will continue to provide quantitative measurements to answer exciting questions like, "Is or was there life on other planets?" PERISCOPE, Probe for Exploring Regolith and Ice by Subsurface Classification of Organics, Polycyclic aromatic hydrocarbons, and Elements, is a next generation spectrometer designed to explore icy worlds like Europa. It uses time-resolved ultraviolet (UV) fluorescence spectroscopy, a technique that identifies organic molecules, polycyclic aromatic hydrocarbons (PAH), and rare earth elements (REE). Photon wavelength discrimination is very important for this technique and is accomplished by a spectrometer. Here, a compact imaging spectrometer is designed to obtain high fidelity spatial and spectral data over the UV, visible (VIS), and near infrared regions (NIR) of the electromagnetic spectrum, corresponding to 276 - 850 nm wavelengths. The Offner-Chrisp spectrometer design geometry is popular due to its high optical performance and small size. In this thesis, an analytical design for an Offner-Chrisp system is used to rapidly obtain an initial design, which is then further explored and optimized using ray tracing simulations. The design meets all instrument requirements and achieves nearly diffraction limited performance throughout much of the spatial and spectral domains in the ray tracing model. This translates to a maximum simulated spatial and spectral resolution of 3 [mu]m and 0.2 nm respectively. A system breadboard is then implemented in the lab using commercial off-the-shelf (COTS) components to test spatial resolution and validate the design concept.

This book was released on 2018-07-08 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development is examined of a prototype multi-channel infrared imaging spectrometer. The design, construction and preliminary performance is described. This instrument is intended for use with JPL Table Mountain telescope as well as the 88 inch UH telescope on Mauna Kea. The instrument is capable of sampling simultaneously the spectral region of 0.9 to 2.6 um at an average spectral resolution of 1 percent using a cooled (77 K) optical bench, a concave holographic grating and a special order sorting filter to allow the acquisition of the full spectral range on a 128 x 128 HgCdTe infrared detector array. The field of view of the spectrometer is 0.5 arcsec/pixel in mapping mode and designed to be 5 arcsec/pixel in spot mode. The innovative optical design has resulted in a small, transportable spectrometer, capable of remote operation. Commercial applications of this spectrometer design include remote sensing from both space and aircraft platforms as well as groundbased astronomical observations.
