A Laser Fuze Scanning System Combining Double Reflection and Transmission
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 reflec-tion 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 scan-ning 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 parame-ters,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 de-sign of the scanning system provided support for the long-distance circumferential detection technology of the la-ser fuze.
