无畸变针孔广角物镜的研究

Study of Pin Hole Wide-Angle Objective without Distortion

随着CCD探测器的出现，针孔广角物镜得到广泛地应用，由于入瞳在针孔广角物镜的外面，畸变难以矫正，它的应用受到限制。在本文中，详细地研究了利用非球面如何矫正光学系统中的畸变，并给出光学系统设计的结果和各种像差曲线。

With the development of CCD detector, pin hole wide-angle objectives haxe widelybeen used. Because the aperture stop is normally outside the pin hole widesangle objective,it is very difficult to correct distortion of the optical system, leading to the application islimited. How to correct the distorti0n of the optical system is presented in detail by useof aspherical surfaces. The results and various aberration curves of the optical system aregiven in this paper
