Research on Modern Testing Technique of Optical System Magnifying Ratio Based on CCD imaging theory

摘要

The paper discusses a new kind of modern testing method used in magnification of telescopic optical system, which applied the technique of photoelectric imaging creation automatically based on DLP theory and the technique of collecting image based on CCD imaging theory. This method simplifies customary measuring process, realizes objective and automatic measuring, and avoids subjective error which artificial factor leads to with using customary testing method, so as to attaining higher testing precision.
