Paper Abstract

A novel means to measure optical multi-parameter is overviewed in this paper and an integrated measurement system consisting of CCD camera, LCD graph generator, testing software and computer is described. Based on this system, novel methods of measuring focal length of lens and visual magnification of infinite conjugate system are given. In addition, the measurement of other parameters such as MTF, parallax, distortion, etc. is also discussed. Three automatic focusing criteria are proposed and selectively used to locate CCD target accurately in the image plane.
