Application of micro-mechanic devices for motion compensation of spaceborne CCD-imaging systems

Remote sensing space missions increasingly use small and microsatellites. I maging systems have to follow this trend by miniaturised technology. In con trast the growing demand for higher geometrical resolutions drives the inst rument sizes by large focal lengths and apertures. A way out is the increas ing of the detectors acquisition time by compensation of the satellite move ment. One method which is suitable for microsatellite applications is the motion compensation by means of controled focus shift on the image plane. The article describes the procedure, experiment and first results of an CCD -camera system using micro-mechanic devices for light tilting. (C) 2000 Els evier Science Ltd. All rights reserved.
