Abstract

Resolution of optical system is a critical index to judge the quality of optical system. Measuring the resolution of optical system has become more and more important in optical measurement. But traditionally the method to evaluate the resolution of optical system is mainly subjective because of man's eye seeing. Although this method is simple and intuitive, it is very easy for the introduction of the subjective error. To solve this problem, an approach based on digital image processing technique is brought out to achieve this subjective processing in this paper. An experiment is done to grasp image of resolving power test target formed by a teleobjective, its extreme resolution is obtained. The result matches ideal resolution by calculation. This way has the advantage of rapid processing and objective. It is the tendency of measuring resolution in the future.
