摘　　要：将可见光与红外光学系统运用分光镜和卡塞格伦平行光学系统组合成平行共光路系统。运用这一特性研发了红外与可见光发射光轴平行度检测仪,用红外和可见光CCD作为传感器。在平行度检测仪前放置标准平面反射镜,进行自准标校。进行平行度检测时,检测仪放置在被测复合光学系统前,标准平面反射镜放置在光学系统后。调整平行度检测仪,使检测仪的可见光轴与复合光学系统的可见光轴平行;再调标准平面反射镜,使可见光学系统成自准直像。以可见光轴为基准,采集检测仪经复合光学系统及标准平面反射镜后的红外像。进行图像分析及数据处理,得到复合光学系统红外光轴与可见光轴的平行度。检测仪的不确定度为3.5″。The visible and infrared optical system was combined into a common path optical system by the beam splitter and the Cassegrain telescope.The infrared and visible optical axis parallelism tester was developed with the infrared and visible CCD as the sensors.Before measuring,a standard flat mirror was placed in front of the parallelism tester for self-calibration.When measuring the parallelism between the visible and infrared optical axis,the tested compound optical system was placed between the tester and the standard flat mirror.Adjusting tester to make the visible optical axis of the tester parallel to that of the compound optical system.Then adjusting the standard flat mirror to obtain the autocollimated image of the visible optical system.Setting the visible optical axis as the data line,the infrared star point image,which transmitted through the compound optical system and was reflectied by the standard flat mirror,was captured.The parallelism between the infrared and visible axis was obtained after the image analysis and data processing.The uncertainty of tester is 3.5″.
