摘要 红外光学系统是红外系统的关健组件,而焦距是光学系统重要的参数之一,它的测量直接影响到红外系统的定位精度和打击目标的准确率。传统的测量焦距的方法一直沿用可见光照明的放大率法,其测量精度受很多因素的制约。研制的测量红外光学系统焦距的系统,采用倒置放大率法测量方式,直接用红外光源照明放置在被测光学系统物方焦面上的玻罗板,用线阵('.CD探测器置于准直物镜的焦面上接收信号,计算机显示测量结果。该测试系统对实际红外光学系统进行了测试,测试结果表明系统稳定性好,测试精度满足设计要求。 The infrared optical system is the very important part of infrared system, and focal length is one of the most important specifications of an infrared optical system. It directly affects the performance of positioning and the accuracy of missiles guidance. The magnified visible lighting method has been adopted in order to measure the focal length of an infrared system. However, it is restrained by many factors. In this paper, a system of measuring the focal length for infrared optical system has been developed, With the inverse magnifying method, an infrared light source is utilized to illuminate the normal object which is located in the front of the focal surface of the infrared optical system. The system received signals by locating the liner CCD detector in the rear of the focal surface of the collimator objective. The results are visualized via a computer screen. The focus of an infrared optical system was measured, and the results showed that the stability of system was good and the measuring precision achieved the designed goal.
