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。
提齣瞭線性雙組聯動型連續變焦光學繫統的一種結構形式。該結構形式是對普通雙組聯動機械補償式連續變焦光學繫統的簡化,其變焦組和補償組全部採用線性運動,減去瞭控製變焦組麯線運動規律的變焦凸輪機構。在像麵位移補償過程中雖然會存在小量像麵位移,但隻要像麵位移量控製在允許範圍內不影響繫統成像質量,給齣瞭線性雙組聯動繫統的具體設計原理和方法。

A kind of linearization double‐linkage continuous zoom lens was proposed .This sys‐tem 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 w ere given .
