摘　　要：文章阐述半主动激光导引头的工作原理,分析四象限探测器输出信号与目标位置之间的关系,并对四象限探测器光斑能量分布关系与线性度进行推导;设计单片透镜、双片透镜组、三片透镜组3款不同的光学系统,以光斑能量照度信息为基础,分析特定视场角范围内光学系统的线性度,最后得到在±15°视场角中线性视场可达±8°的光学系统。Based on the working principle of the semi-active laser seeker,this paper analyses the relationship between the output signal of the four-quadrant detector and the position of the target.The distribution of the spot energy detected by the four-quadrant detector is obtained,and its linearity is analyzed.Three different optical systems featured by a single-lens,a double-lens group,and a triple-lens group are designed,respectively.Taking the spot illumination information as a reference,the linearity of the optical system in a certain scope of view angle is analyzed.Finally,an optical system with a linear field view up to±8°at a view angle of±15°is developed.
