General model of transmission grating diffraction efficiency

摘要: 在远场条件下采用夫朗和费衍射近似,经过波动光学的计算推导,得到透射光栅各级绝对衍射效率及相对衍射效率通用计算模型.此模型可以用来计算任意栅线截面情况下透射光栅的衍射效率.利用此模型,分别建立了矩形、梯形和5边准梯形截面的衍射效率计算模型,并对模型正确性进行了验证.

Abstract: In the Fraunhofer diffraction approximation, a general model for calculating the transmission grating diffraction efficiency is deduced from wave optics under the condition of far field. Diffraction efficiency of transmission grating with any cross section can be obtained from such a general model. Rectangular, trapezoidal, 5-side quasi-trapezoidal and 7-side quasi-trapezoidal cross section calculation method are established with this model. And two examples are given to demonstrate the correctness of this general model.
