| 摘 要： | 利用二元光学元件消色差和对波面进行任意整形的特点，将二元衍射面应用于红外双焦光学系统中，对变焦方程的解进行了分析，给出了具体的系统设计实例.设计结果表明，在仅使用4片锗透镜的情况下，系统焦距为80 mm，F数为0.8时，系统垂轴像差小于72μm，在10lp/mm时光学传递函数大于0.8；系统焦距为160mm，F数为1.6时，系统垂轴像差小于35μm，在10lp/mm时光学传递函数大于0.7.关键词：红外变焦光学系统折射/衍射混合透镜光学设计

| Abstract: | The application of diffractive surface in the bifocal optical system is investigated by taking the advantage of the negative dispersion and the arbitrary phase modulation characteristics of binary elements, an analysis on the zoom equation is made and a sample design is presented. It is shown that good imaging quality can be achieved with the implementation of only four Germanium lenses. When the focal length of the system is 80 mm and the F-number is 0.8, the longitudinal aberration is less than 72 μm, the modulation transfer function (MTF) of 10 lp/mm is greater than 0.8 ；when the focal length is 160 mm and the F-number is 1.6, the longitudinal aberration is less than 35 μm, MTF of 10 lp/mm is greater than 0.7. |
