厚全息光柵的近似分析方法

An Approximate Analytical Method for Thick Hologram Gratings

从薄光栅的衍射理论出发,对体全息光栅的衍射效率提出了一个近似、直观、简捷的分析方法。得到了与Kogelnik H相同的结果,从而将薄光栅理论与厚光栅理论联结起来。

An approximate, intuitive and simple analytical method based on thin grating theory, is presented for the diffraction effect of thick hologram gratings.Neverthless this method leads to the same couple wave equation as Kogclnik H. Therefore, this method is a connective path between thin and thick grating theory.
