摘　　要：为了解决高精度瞄准镜性能检测难点——检测各种环境试验条件下的零位走动量,设计了基于CCD图像检测技术的测试系统,该系统通过对高精度瞄准镜连接座上定位点试验前后位置测量,获得定位点位置差量,依据位置差量调整枪镜固定基座,使瞄准镜的连接座上的定位点复原至试验前位置,进而测量、计算出零位走动。通过对平行光管、CCD光学系统焦距的计算和系统精度分析,并经实际工程应用可知,测量精度不大于2.16″,测量范围不小于4320″,达到检测指标要求。结果表明,该测试系统检测方法正确可靠、检测精度高,为高精度瞄具零位走动的检测提供了方法。In order to solve the difficulty of the performance testing of high precision sighting telescope, i.e. , testing its sight-line alteration under various environmental test conditions, a test system was designed based on CCD image test technology. Firstly, the position difference of the anchor was measured through measuring the positions of the connection seat anchor points before and after test. Secondly, according to this data, the fixing base of the precision sighting telescope was adjusted to make the connection seat anchor recover to the initial position. Finally, the alteration of the sight-line was measured and figured out. Based on an optical collimator, the focal length of the CCD optical system was measured and the system accuracy was analyzed. Inpractical engineering applications, the measurement error was less than 2. 16＂ and measuring range was larger than 4320＂, which met the project requirements. The results show that the test method is accurate and reliable and detection precision is high. This test system offers a method for testing the sight-line alteration of high precision sighting telescopes.
