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。

In order to meet the special requirements of a linear Charge-coupled Device(CCD) camera used in a 2-D localizer system,a new video lens design is proposed,in which a spherical lens is used as the front element and a cylindrical lens is used as the back element.

针对使用线阵列电荷耦合器件(CCD)的二维位置定位系统中的光学系统的特殊要求,本文提出一种以球面镜作为前组柱面镜作为后组,前组像面作为后组物面的二级成像结构作为线阵CCD的摄像镜头。
