变焦距系统设计的快速求解

A Rapid Computing Method of Zoom Optical Design

变焦距光学系统已经在各种光学仪器上获得了广泛的应用 ,一些新的设计思想也层出不穷。本文介绍的变焦距系统设计的快速求解方法可以贯穿到变焦距镜头设计的全过程 ,还可以应用到光学系统的初始求解、设计过程中的抽样计算、设计数据的校对和审核、结构设计中驱动凸轮曲线的求解、外观设计等。本文列举的计算实例说明 ,这种快速求解对完成一项设计具有很多方便。

Zoom optical systems have been widely used on all kinds of optical instruments,and more and more new design methods have been employed. Maybe all designers need the innovation to proceed with the design of optical imaging instruments. In this paper a rapid computing method of zoom optical design is reported, which can be applied to initial solution of optical system, sample computation in design process, check and audit of design data, resolve of driving cam curve in structure design and aspect design etc. The examples listedin the paper show how fine this method is in the design of a zoom system.
