Paper Abstract

Gimbals have been the main mechanism to perform pointing and beam steering for most Electro-optic sensors. A new class of pointing and beam steering devices based on a pair of counter-rotating Grisms is presented here. The device is capable of wide spectral band. The paper first describes the design principles of counter-rotating Grisms for beam pointing and beam steering. Comparison between gimbals and counter-rotating prisms is given next. Finally potential applications of a pair of counter-rotating grisms are illustrated.
