Optical scanning device, particularly for seeker heads in target seeking missiles

摘要

An optical scanning device comprises a bearing portion (12), which is rotatably mounted in a base portion (10) about an axis of rotation (16). A holder (18) is rotatably mounted in the bearing portion (12) about an axis of rotation (22), which is eccentric with regard to the axis of rotation (16). A pair of lenses (26,38) is located eccentricly in the holder (18) and forms part of an imaging system, through which a field of view is imaged in the plane of a base portion-fixed detector. The bearing portion (12) and the holder (18) are driven in opposite directions.
