摘要
利用标量衍射理论推导了分频光栅的衍射效率公式 ,并在此基础上分析了它的衍射特性及入射角误差对衍射效率的影响 。
An analytic expression of diffraction effciency of color separation grating (CSG)is deduced from the scale diffraction theory.Moreover,the diffraction characteristics of CSG and the incidence errors are analyzed.Some useful conclusions for practical application have been drawn in the end.
