【摘要】 针对大视场高变倍比宽波段光学系统的特点,运用换根方式机械补偿光学系统设计技术和h-hp图及孔径图分析法,实现了38×变倍比,解决了大视场宽波段系统的初、高级像差难以平衡的难题,同时提出运用凸轮程序公式编程计算不齐焦段的补偿组实际位移量,对Code V的凸轮曲线设计值进行修正的方法,保证了高变倍比光学系统的齐焦性。更多还原

【Abstract】 According to the characteristics of large FOV high zoom ratio wideband optical system,a 38× zoom ratio was designed,the primary and advanced aberrations of large FOV wideband system were balanced by using the mechanical compensation technique of changing root,the h-hp diagram and the aperture diagram analysis.A method using the cam formula to calculate the displacement of compensation group with no parfocality by programming and modify the design value of cam curve in Code V was put forward.This method ensured the parfocality of the high zoom ratio optical system.更多还原
