Research on Optical System Based on Dual-Wavelength Laser Fuze

针对激光引信应用双波长辐射源进行目标探测识别的需求,设计了一种发射、接收光学系统。该光学系统工作于紫光和红外光两个波段,具有结构简单、体积小等优点。通过光学整形,引信辐射光束均匀分布于光学视场中,且两种波长的光学视场有效交叠,通过光学系统的收、发配合能够准确获取引信目标的回波信息。

According to the requirements of laser fuze towards target detection using dual-wavelength,an emitting and receiving optical system is designed. The optical system which works in purple and infrared wavelength has a simple and compact structure. Emitting beams of laser fuze get even distribution and the optical fields of dual-wavelength overlap after optimization. The echo information of laser fuze target can be acquired accurately through the cooperation of receiving and emitting of optical system.
