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。 Aiming at the characteristics of wide-band optical system with large field of view and high zooming ratio, a 38 × zoom ratio is realized by using the mechanical compensation optical system design technique and the h-hp chart and aperture map analysis method. Band system is difficult to balance the initial and advanced aberration, while the use of the cam program formula to calculate the actual compensation of the misaligned focal length of the displacement group, the cam curve of the Code V to correct the design values ​​to ensure a high zoom ratio Optical focus of the system.
