Three-Axis Image Stabilization With A Two-Axis Mirror
George R. Lewis · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1990
Long Range Oblique Photographic (LOROP) cameras must provide quality images at long ranges despite distur bances from the carrying aircraft. A method of reducing these disturbances is termed image stabilization, and usually. consists of both passive and active mechanisms. Two-axis gimballing of a pointing mirror for the camera has proven. to be adequate to provide three-axis image stabilization. This paper describes the technique and the equations govern-, in.g the stabilization.
