摘　　要：提出了线性双组联动型连续变焦光学系统的一种结构形式。该结构形式是对普通双组联动机械补偿式连续变焦光学系统的简化,其变焦组和补偿组全部采用线性运动,减去了控制变焦组曲线运动规律的变焦凸轮机构。在像面位移补偿过程中虽然会存在小量像面位移,但只要像面位移量控制在允许范围内不影响系统成像质量,给出了线性双组联动系统的具体设计原理和方法。A kind of linearization double-linkage continuous zoom lens was proposed.This system utilized the simplified configuration of the conventional double-linkage continuous zoom optic system with mechanical compensation,its zoom group and compensation group both used linear motion,and the zooming cam mechanism for controlling the curvilinear motion discipline of zoom group was omitted.This configuration had a few image displacement,however,it could not influence the image quality when the image displacement was controlled in allowed range.In addition,the principle and method for designing linearization double-linkage zoom lens were given.
