| 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。

| Abstract: | 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. |
