根据激光制导目标方位探测系统技术指标,分析了系统光学设计的特点,选定了光学系统的结构形式,探讨了激光回波光斑大小与四象限探测器光敏面大小之间的相互关系及其对目标探测跟踪的影响,并利用ZEMAX软件进行了系统参数优化,设计结果满足了使用要求.

According to technical requirements of a laser seeker, this paper analyses the characteristics of optical design, and selects the structure of optical system. The relationship between the optical spot radius of laser echo and the detecting area of the quadrant detector has effect on acquisition and tracking of laser guidance, so this effect is explained in detail. Optical parameters are optimized by using the ZEMAX software. From the results, one conclusion is drawn that the project is satisfied the requirements for operating.
