Abstract
The precision optical system is included in laser fuze, among them, an important role is played by the optical receiver system, when it is used in conventional ammunition, high emission overload environment has a serious impact on the quality of weak echo focusing, system reliability can not be guaranteed. The receiver focusing lens and integrated program of narrow band filters are proposed, a new type of receiver system optical buffer structure was designed, a mathematical model of tradition receiver system and a mathematical model of new structure were established by using finite element analysis software ANSYS, nonlinear dynamics simulation and optical simulation were did by ZEMAX to the receive focusing lens; finally, the air gun impact experiment was did. The results show that in the experience of the 70 000 g impact acceleration, buffer structure of the new optical system can alleviate the receiver focusing lens plastic deformation effectively, the quality of pulse laser beam focusing plastic can be improved, the laser echo energy is enhanced significantly. A new method and theoretical basis are provided to the anti-overload design for conventional weapons of laser fuse receiving optical system.
