用于全景成像系统的一种新型光学非球面

A Novel Optical Aspherical Surface for Panoramic Imaging System

介绍一种用于全景成像系统的单个复杂非球面前置元件,从几何光学的基本原理出发,给出了这种非球面的高斯分析和不同情况下的面形方程,利用正交拟合算法得到了便于实现光路计算的多项式表述,并成功地运用于光线追迹和像差计算。

Single fore-element with complex aspherical surface used for panoramic imaging system is presented in the paper. Proceeding from the basic principle of geometry optics, the Gaussian analysis is derived and a group of equations for the surface form under the different cases are given. A series of polynomial expressions are obtained by use of orthogonal fitting algorithm. These expressions have been successfully applied to ray tracing and aberration calculation.
