Taking aim at the modern testing requirement of exit pupil diameter,distance and magnification of optical sighting telescope,based on the traditional testing principles and methods,the proposed system was designed by the modern optical measuring principle and method,such as the CCD shooting,precision machinery,optics and computer control and image processing.In the testing process,the resolution of image and the location accuracy of target image were greatly improved by the subdivision technology.The testing accuracy of diameter and distance of exit pupil is 0.01 mm,the testing range is 1~100 mm,and the testing accuracy of magnification is less than 1%,and the eye fatigue strength is greatly lightened.
