Abstract:
    The device is mainly composed of reflecting telescope system, beam splitter, variable density attenuation disc, high voltage amplifier, CCD camera, data acquisition system, industrial control computer, and software control system based on genetic algorithm. Using secondary mirror of the reflecting telescope being as wave front phase corrector, the invention can adjust alignment between primary mirror and secondary mirror of the reflecting telescope automatically under condition of not introducing additional part of aberrational correction. The invention can corrects static and quasi-static aberration of the reflecting telescope as well as aberration brought by each optical part self in selfadaption. Advantage are: compact structure, simple control, and easy of implementation. The invention reduces system error of reflecting telescope imaging greatly, raises imaging capability of the telescope.
