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 comprehensive 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 optimized 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.
