摘　　要：详细介绍了一种基于二元光学的闪耀光栅的设计方法,并利用傅立叶变换和二元光学理论推导了此光栅的衍射效率公式以及实现闪耀的条件,并利用matlab分析了各级衍射效率,证明可对特定级次实现闪耀。A new design for blazed grating based on binary optics is introduced. The diffractive efficiency and the condition to realize blazed grating are derived by Fourier transform and binary optics. The diffraction efficiency of the diffraction orders is analyzed by matlab, and some certain diffraction order being blazed is proved.
