Experimental research on active image motion compensation with high angular velocity searching system

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.
