摘　　要：在满足机载吊舱型光电测量电视小空间、大振动环境要求及CCD成像尺寸为Φ80μm、目标截面长度尺寸为2m、距离为10km的工作条件下,对某可见光测量电视进行了光学设计,其焦距为400mm,口径为65mm。采用分析计算的方法对所设计的光学系统的焦距、目标/背景对比度进行了相应的估算分析,得到了相应的目标/背景比值结果,从而对该电视的探测距离进行了校核分析,可以认为此可见光电视光学系统满足系统的远距离探测要求。The optics design of the visible light TV was done.Its focus is 400mm,and caliber is 65mm.This TV can satisfy some special requests to the plane carrying cabin,such as small space,high libration,Φ80μm CCD imaging dimension,2maim section length and 10km detecting distance.The focus and aim/background contrast of the optics system was calculated and analyzed using calculation method.The aim/background contrast result was gained and used to check and analyze the detecting distance of the TV.It can be seen that this short focus television can satisfy the long distance detecting request.
