摘要

为了寻找新的变倍补偿方式并降低设计变焦距系统时对经验的过分依赖

提出了一种光焦度分配及变焦补偿方法。首先以组元之间的间隔为初始量

把组元的运动形式作为自由量

通过计算公式求出满足间隔要求的光焦度分配和组元运动形式。这种方法在一定程度上降低了变焦系统光焦度分配的难度

同时为探寻新的变焦运动方式提供了新的思路。为了验证该方法的可行性

以三组式变焦系统为例

在同一指标下得到了4种不同的变焦运动方式。比较几种运动形式后认为三组全动型变焦方式为最优变焦方式。计算结果表明

得到的4种变焦方式的计算结果和优化后的结果都很接近

验证了该方法的准确性。

Abstract

In order to arrive a new compensation mode that reduces the dependence on design experience for a zoom lens

a way for power allocation and compensation is proposed. Taking the group space as initial parameters

we can determine the corresponding power allocation and actions of each component. This method helps to reduce the difficulty of power allocation and provides different ways to find the new compensation mode. In order to test the feasibility of this method

we use a three-component zoom lens for the same target with four different moving modes.The experiment results indicate that an all-movable mode is the optimum mode and theoretical results approach this optimum.
