摘　　要：在对传统的视差测量方法进行充分研究的基础上,提出了基于自动调焦技术的轻武器光学瞄具的视差参数测试方法。介绍了自动调焦技术的工作原理及其系统组成框图;根据轻武器瞄具性能指标的具体要求,结合自动调焦技术设计了一套轻武器瞄具的视差参数测试系统,并介绍了被测瞄具放入该测试系统前后的自动调焦过程;最终通过求取视度之差得到视差。根据轻武器瞄具光学系统的实际测试要求进行了5次测试实验,并对这5次实验数据进行了分析。结果表明:视差测试精度为0.0296m-1,达到了轻武器光学瞄具技术指标<0.1m-1的要求,保证了测量精度。According to the research of traditional parallax measuring techniques, a parameter test method based on the auto-focus technology was proposed, and the principle of auto focus and its composition block diagram were introduced. Then, in consideration of the specific requirements of small arms for sight performance, a parallax test system was designed combined with the auto focus technology and the auto-focus processes before or after the measuring sight placed in the test system were described in detail. Furthermore, the parallax parameters were obtained according to the difference of diopter. Five experiments were performed on the requirements of the actual optical system, and the obtained parallax parameters were analyzed. Results show that the measurement accuracy of parallax parameters is 0. 029 6 m^-1, which achieves the technical specification less than 0.1m^-1 and guarantees the measuring accuracy.
