摘    要: 根据四象限探测器的工作原理,激光半主动导引头光学系统所成光斑需均匀分布在探测器靶面上。首先分析此类光学系统像差特点,提出像差的设计方案,然后通过使用CODE V设计一套光学系统,利用痕迹图、包围能量等定性评价系统光斑质量。在不同视场时,通过LightTools光机分析软件追迹1×106根光线,得到探测器靶面的光线分布,利用Matlab处理数据并绘制角度-输出响应曲线,利用该曲线可精确评价探测器靶面的光斑性能。

关 键 词:激光导引头  光学系统设计  四象限探测器  激光半主动寻的制导

Abstract:According to principles of quadrant detector, light spots of laser semi-active seeking guided seeker optical systems should be formed on the target surface of quadrant detector uniformly. This paper firstly analyzed the aberration characteristics of these optical systems and presented a method for correcting the aberrations, then designed an optical system by CODE V, evaluated the spots quality of the optical system qualitatively by the footprint and the encircled energy. 1×106 rays were traced by LightTools to obtain the distribute of the rays on the quadrant detector for various fields of view. The target angle-output response curve which could evaluate the performance of light spots precisely was plotted by Matlab. The article provides reference for the optical system design of laser semi-active seeking guided seeker.
Keywords:laser seeker  optical system design  quadrant detector  laser semi-active seeking guidance
