| 摘 要： | 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.该镜头使具有相同一维坐标值的点成像为同一条直线,并且具有广角视场,畸变小,成像质量优良等性能特点.对其设计思想、像差特点进行了分析,并给出了f'=.20 mm,2ω=74,畸变小于1.6%的柱面镜摄像镜头实例及其像差和传递函数计算曲线.

| Abstract: | 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.The image plane of the front element and the object plane of the back element share the same position.The video lens has the wide field of view,small distortion,and highly imaging ability.By the lens,the spots equidistant from the basic shaft(eg.x sha... |
