用平面全息衍射理论计算体全息光栅的衍射效率

Calculation of Diffraction Efficieneies of Volumetric Hologram Gratings on the Base of Planar Hologram Diffraction Theory

将体全息光栅视为许多平面全息光栅的集合,利用平面全息衍射理论导出体全息光栅衍射的耦合波方程。

In this paper,the author considers the volumetric hologram grating as an assembly of a great number of planar hologram gratings.And,using the planar hologram diffraction theory,the coupled wave equations of the volumetric hologram grating diffraction have been derived and the diffraction efficiencies obtained.
