Abstract

This paper describes a commercially available instrument, CASI (Compact Airborne Spectrographic imager), designed for remote sensing. The instrument is capable of medium-resolution multispectral imaging of both local and distant astronomical objects. The instrument employs a GEC UT1O4 CCD to provide an overall spectral resolution of 1.8 nm and a peak quantum efficiency of 10% at 575 nm. The spectral range of the instrument is 450 nm to 900 nm, with 512 active pixels in the spatial imaging direction. Integration times are variable from several seconds down to 10 ms. A fiber optic tap intO the spectrograph slit enables a real-time spectral calibration to be recorded with the data. The results obtained observing several astronomical objects are presented.
