以传统 4片 70°视场蔡司目镜为基础 ,用折 /衍混杂单透镜代替系统中的双胶合透镜 ,给出了衍射面分别位于单透镜两面不同位置时的折 /衍混杂目镜系统。结果表明 ,所设计的折 /衍混杂系统优于传统蔡司目镜 ;垂轴色差降低了 1个数量级 ,像散降低了 34% ,垂轴像差对于 0°、4 9°和 70°视场分别降低了30 %、16 %和 2 0 % ;系统的重量和尺寸有了很大的改善 ,分别降低了 5 7%和 10 % ,该折 /衍混杂目镜满足现代化广角 70°视场的头盔系统的一般要求
Based on the traditional 4-lens Zeiss eyepiece with 70 ° field of view, the double / double hybrid lens in the system was replaced by the single / double hybrid lens, and the folded / mixed hybrid eyepiece system with diffractive surfaces at different positions on both sides of the single lens was given respectively. The results show that the designed folding / diffracting hybrid system is superior to the conventional Zeiss eyepieces; the vertical axis is reduced by 1 order of magnitude, the astigmatism is reduced by 34%, and the vertical axis aberration is 0 °, 49 ° and 70 ° respectively Reduced by 30%, 16% and 20%; the weight and size of the system have been greatly improved, respectively, a decrease of 57% and 10%, the folding / hybrid hybrid eyepiece to meet the modern wide-angle 70 ° field of vision helmet system The general requirements
