摘　　要：对于宽入射角工作的衍射光学元件,提出了高带宽积分平均衍射效率的优化设计方法。通过复合带宽积分平均衍射效率的最大化设计,得到设计波长和设计入射角度,进一步可以计算得到微结构高度。分析了衍射效率对折衍射混合光学系统调制传递函数的影响。优化设计了一套含有衍射光学元件的折衍射混合目镜系统。目镜由三片透镜组成。考虑衍射光学元件的衍射效率,最大视场处目镜系统的调制传递函数高于0.42。该方法为混合光学系统的像质评价提供了依据。An optimal design method of high polychromatic integral diffraction efficiency(PIDE)was proposed for DOE working within wide incident angle.Through the maximization design of com-prehensive PIDE(CPIDE),the design wavelength and the design incident angle were obtained,and the microstructure height could be calculated.The effect of diffraction efficiency on the modulation transfer function of hybrid optical systems was analyzed.A hybrid eyepiece system with DOE was op-timized with three lenses.Considering the diffraction efficiency of the DOE,the MTF of the eyepiece system at the maximum field of view was higher than 0.42.This method could provide the basis for image quality evaluation of hybrid optical systems.
