Determining the Operating Characteristics of an Ultraviolet Interferometric Spectrometer

摘要

A prototype interferometric spectrometer system is being built by NASA to explore the potential of the technique for applications involving the visible and near ultraviolet portions of the electromagnetic spectrum. The system is limited only by the frequency bandpass of the optical components used in the system, the quality of the optical components, and ultimately by the memory capacity of the computer; tradeoffs between the wavenumber resolution of the produced spectrum, the bandpass limits of the optics, and the number of samples obtained from the interferogram must be delineated explicitly. The prototype Ultraviolet Interferometric Spectrometer (UVIS) instrument is expected to be configured several different ways to ascertain its suitability for various applications. To exploit its inherent flexibility, this reference document describes these parameter tradeoffs.
