Image shift suppression based on flexure support mirror in circumferential scanning photoelectric reconnaissance systems
In order to suppress the image shift of the circumferential scanning photoelectric reconnaissance system and reduce the false alarm rate, flexure support vibrating mirror was used for high-frequency image shift compensation. The composition and basic principle of the image shift compensation system were analyzed, and a flexure support structure was used instead of a bearing support structure. The transfer function model of the compensating vibrating mirror was given. A test system for the image shift compensation effect of the flexure support vibrating mirror, including the target, azimuthal turntable, image shift compensation vibrating mirror and other functional parts, was constructed. The results show that: The image shift compensation vibrating mirror swing sweep frequency is greater than 105 Hz, the uniform time is greater than 5.5 ms, the speed stability is greater than 99.60%, the detector imaging is clear, obviously inhibit the image shift, the flexible support vibrating mirror can meet the circumferential scanning photoelectronic reconnaissance system of high-frequency image shift compensation. This study is informative in the field of image shift compensation for circumferential scanning photoelectric reconnaissance system for high-frequency imaging detection.
