一种新型激光周视引信光学系统

A novel optical system for laser panoramic fuse

通过对一般激光器的发光特点及柱面镜的光学特性进行分析，提出一种新型激光周视引信光学系统——柱面镜系统，即采用2个弧矢面正交的柱面镜组来改善激光束散角，以4个扇区来完成空间的周视功能。由于在半径为0．5～10m的圆周上光能量均匀性非常好，且系统光路具有可逆性，因此可用于大视场发射和接收的导弹引信中。该系统结构紧凑，易于加工和安装。靶场试验证明了该光学系统的可行性和实用性。该光学系统可代替目前仍在使用的反射式光学系统。

Based on the analysis of the luminous characteristics of typical lasers and optical properties of cylindrical lenses, a novel optical system for laser panoramic fuse, which uses two sets of cylindrical lenses with orthogonal sagittal planes to improve the scattering angle of laser beam and uses four sectors to realize the panoramic function, is proposed in this paper. Since the distribution uniformity of the light energy of the system is satisfactory on the circle of 0. 5-10 m radius and the beam path of the system offers an advantage of invertibility, it can be used in the fuse of the missile with the feature of WFOV emission and reception. The system is comparable to its counterpart abroad. The system is compact fabricated. The demonstration in the test range proves the new practical. The reflective optical system available will be replaced in structure and easy to be optical system is feasible and by this system in the future.
