IMAGING SYSTEMS

Abstract

An imaging system for collecting radiation from a scene and producing an image of the scene includes first and second scanning rotors, said first scanning rotor having a set of n1 plane mirrors which extend around the first rotor axis, said second scanning rotor having a set of (n1 +n2) plane mirrors which extend around the second rotor axis (where n1 and n2 are integers), wherein adjacent mirrors in said first and second sets are inclined at different angles to the axes of first and second rotors respectively, and wherein the rotors are arranged such that radiation from said scene is reflected from one of said sets to the other, and means for driving the first rotor at ##EQU1## x speed of the second rotor.
