Calculation of initial configuration for 15× double-linkage infrared continuous zoom system

摘要: 双组联动型变焦结构是由2个固连在一起的变倍组做线性运动，补偿组做非线性运动的变焦系统，兼有光学补偿和机械补偿两种特点，较易实现大的变倍比，系统长度较短且凸轮曲线较为平缓。求解变焦各组份高斯参数的出发点是保证变焦核能够实现所需变倍比的情况下，各个运动组份的位移之和为零且像面稳定。利用PW法与光学结构参数之间的关系确定各组份的半径和材料，最后利用CODEV软件设计出满足设计要求的初始结构。Abstract: Double-linkage zoom structure is composed of two groups connected together which is the zoom group for doing linear motion and the compensation group for doing non-linear motion. This structure has the characteristics of both the optical compensation and the mechanical compensation. This structure is easy to realize large zoom ratio, the system length is short and the cam curve is smooth. The radii and materials of components were established by using the PW method and the optical structure parameters relationships, and the initial structure meeting the design requirement was designed by CODEV software.
