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.
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。
