Abstract

Imaging spectrometry is a field which has demonstrated remarkable growth in recent years. The driving force behind the interest in this field is the additional information made available when both spatially and spectrally resolved signals are collected simultaneously. In the past, these data have tyically been collected sequentially (point by point) or by means of photographic detection. However, several imaging spectrometers have recently been described which permit collection of spatially-resolved, wavelength-specific images with multidimensional detector arrays (e.g., vidicon tubes, photodiode arrays, charge-transfer detectors, etc.). These spectrometers allow an image to be acquired much more rapidly than was previously possible, and therefore enable new experiments which previously were difficult or impossible to perform. Unfortunately, these spectrometers also suffer from their own unique set of problems, including variations in the optical throughput of the spectrometer as a function of spatial position in the image plane (e.g., vignetting), and differences in pixel sensitivity on the detector array. In the most extreme case, these problems can overwhelm the signal and cause them to be unusable.
