摘要
归纳了远目标经过光电成像系统到输出清晰图像的过程中需满足的条件,针对相应的指标要求,分析了光电系统的分辨率、几何探测能力和像面照度,确定了光学镜头的焦距、相对孔径等主要设计参数。综合考虑大气传输、光学系统及CCD探测器等影响因素,讨论了整个舰载光电系统的对比度和探测能力,对光学系统的各项性能参数进行了优化匹配。最后,在外场试验中基于所研制的光学镜头验证了舰载光电系统的探测能力,结果显示其满足探测距离≥18km的指标要求,表明所提出的理论分析合理可行,可用于车载及机载光学系统设计。
Key techniques to obtain a sharp image of the long-range target through an opto-electronic tracking system were summarized.To insure the major design parameters of an optical system,the resolution,detection ability and the image plane illumination for the opto-electronic system were analyzed.Based on the effects of atmospheric transmission,optical system and CCD detector,the objectbackground contrast and the detection ability of a shipborne optic-electronic system were discussed,and the focal length and relative aperture of optical system were reasonably chosen.At last,the detection ability of shipborne optic-electronic equipment was tested on fields based on the developed lens.The results show that the system can meet the demand of the detection range larger than 18 km for flying targets at sea.It provides important testing data and theoretical reference for the design of shipborne opto-electronic system.Meanwhile,the design theory of shipborne optical system is suitable for the designs of vehicle and airborne equipment.
