多组元全动型变焦距透镜高斯光学参数的求解方法

在求解多组元全动型变焦距透镜高斯光学参数的过程中，不再区分变倍组与补偿组的概念，统一将变焦距系统运动组元的移动距离和焦距作为变量，并将组元的F数作为约束条件，提出了一种能同时求解多组元全动型变焦距系统在每个变焦位置高斯光学参数的计算方法，并给出了设计实例，证明了算法的可行性，提高了光学系统设计的智能化程度。

Method of Determining Gaussian Parameters for Zoom Systems with Multiple Moving Lens Groups

A new computable method of determining Gaussian parameters is presented for zoom systems with multiple moving lens groups. These lens groups are no longer divided as focus changing groups and compensating groups. Displacements and focal lengths of all the moving lens groups are taken as variables in optimization, and the Gaussian parameters are solved for all the focal positions simultaneously, with the F-number of each lens group constrained to a rational value. A test program is developed using the algorithm. The results of a design example show that the method is practical and is a step toward the intelligent computer-aided design of zoom systems.
