摘　　要：针对激光引信周向扫描系统光束发散角大且存在扫描盲区的问题,设计了一种基于双反射与透射结合的激光引信扫描系统。阐述了系统结构尺寸的约束并通过光线追踪分别对系统扫描过程中光束发散角和扫描角度进行了仿真,并研究了超环面和六棱台镜面的面型参数调整与光束发散角、扫描角度之间的影响。仿真结果表明:通过控制光阑位置可以实现单窗口的扫描角度达61°,六窗口组合可实现无盲区扫描;通过调整反射面参数来矫正透射场曲可实现全扫描角度光束最大发散角为0.034°;扫描路线会出现波浪式起伏,需要进一步匹配收发视场实现远距离无盲区扫描。该系统为激光引信远距离周向探测提供了技术支撑。In order to solve the problems of large beam divergence and blind scanning areas in the circumferential scanning system of a laser fuze,a scanning system for the laser fuze based on the combination of double reflection and transmission was designed.The constraints of the system structure and dimensions were detailed,and the beam divergence angle and scanning angle of the system during scanning were simulated through ray tracing.The relationships between the adjustments of the surface parameters of the hypercyclic and hexagonal mirrors and the beam divergence angle and scanning angle were investigated.The simulation results showed that a scanning angle of up to 61°for a single window could be achieved by controlling the position of the diaphragm,and blind-free scanning could be realized with a six-window combination.By adjusting the reflective surface parameters,correction of the transmitted field curvature could be realized,allowing for a full scanning angle beam with a maximum divergence angle of 0.6 mrad.The scanning route would exhibit wave-like undulation,necessitating further matching of the transceiver field of view to achieve long-distance scanning without blind spots.The design of the scanning system provided support for the long-distance circumferential detection technology of the laser fuze.
