Paper Abstract

Imaging spectrometers operating in the visible through midwavelength infrared (MWIR) spectral regions have been used or planned for several missions in the exploration of the solar system. These instruments generally require cryogenic cooling for their photo-detector arrays. A current concept of the instrument system is described herein. The feasibility of an uncooled imaging spectrometer is assessed through evaluation of the tempera-ture environments of the instrument in various spacecraft orbits, and by analysis of available photo-detector materials and sensor focal plane array configurations. It is concluded that the uncooled approach appears practical for many solar system missions with current technology.
