摘　　要：针对光学瞄具出瞳直径、出瞳距离与放大率的现代测试要求,在分析原有传统的各种检测原理与方法的基础上,本系统采用了一种基于CCD摄像技术、精密机械技术、光学技术和计算机控制与图像处理技术的现代光学测试原理与方法。测试过程中采用CCD细分技术,提高了图像的分辨率和目标图像的定位精度。出瞳直径与出瞳距离测试精度达到0.01 mm,测试范围为1-100mm,放大率测试精度小于1%,而且大大减轻了疲劳强度。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.
