摘　　要：介绍了四象限探测器用于激光制导的工作原理,根据激光制导的技术要求和四象限探测器的工作特性,分析了基于四象限探测器进行空间定位的导引头中光学接收系统的原理及特点。依据系统指标,采用序列性光线追迹和非序列性光线追迹相结合的方法,设计了一种±4°线性接收视场内光斑均匀性大于75%,±1.5°接收视场内光斑均匀性大于90%的接收光学镜头,同时镜头在±4°线性接收视场内光斑直径偏差小于±0.05mm。镜头设计结果既满足设计要求又结构紧凑,对此类镜头的光学设计方法进行了探索总结[1]。The working principle of the four-quadrant detector used in laser guidance is introduced. According to the technical requirements of the laser seeker and the working characteristics of the four-quadrant detector, the principle and characteristics of the optical receiving system in the seeker based on the four-quadrant detector for space positioning are analyzed. With the sequential ray tracing and non-sequential ray tracing, an optical lens is designed. Its illumination uniformity is more than 75% in the ±4°linear receiving field. Its illumination uniformity is 90% in the ±1.5° receiving field. At the same time, the spot diameter deviation of the lens in the 4 linear receiving field is less than 0.05mm. The lens design result not only meet the design requirements but also have a compact structure.The optical design method of this kind of lens is explored.
