Paper Abstract

Hyperspectral imaging from space requires a very efficient, low f-number optical system to obtain a 20 - 30 m GSD without ground motion compensation. The combination of a folded Schmidt telescope with a Dyson spectrometer meets these requirements while retaining spectral purity. We present the basic design of an instrument that images at f/1.2 with high resolution: with a 300 mm focal length it has a 4 degree field with 20 m GSD and 40 km ground swath from 600 km altitude. Various capabilities, problems, and design options of the Schmidt-Dyson combination are discussed. Detailed design for a specific application remains to be done.
