An ultra-high angular velocity and minor-caliber high-precision stably control technology application for active-optics image-motion compensation, is put forward innovatively in this paper. The image blur problem due to several 100°/s high-velocity relative motion between imaging system and target is theoretically analyzed. The velocity match model of detection system and active optics compensation system is built, and active optics image motion compensation platform experiment parameters are designed. Several 100°/s high-velocity high-precision control optics compensation technology is studied and implemented. The relative motion velocity is up to 250°/s, and image motion amplitude is more than 20 pixel. After the active optics compensation, motion blur is less than one pixel. The bottleneck technology of ultra-high angular velocity and long exposure time in searching and infrared detection system is successfully broke through.
In high searching and scanning angular velocity infrared warning system, the relative motion always exists between the imaging system and targets during the camera exposure time. Images of targets are not static but dynamic on the FPA, which will blur the target image and decline the image quality. Focusing on high angular velocity searching, long-time of exposure, high precision, high demand of real-time process and other applied characteristics, the authors create an experiment platform of active optics image motion compensation by setting experiment parameters systematically. Active optics image motion compensation experiments based on swing mirror are developed. Results of experiments presents active inversely optical image motion compensation through swing mirror can eliminate the relative motion caused by high angular velocity searching and scanning. Pixels of blur image are less than one pixel under the conditions of 250°/s angular velocity and 500μs exposure time in this experiment.
