体全息光栅平均介电常数的变化对其衍射效率的影响和补偿

Effects of the Change in Average Permittivity of Volume Hologram Grating on Its Diffraction Efficiency And Compenstion

本文研究了一个描述光波在全息体光栅内的传播模型,并将此结果与Solymar获得的结果进行了比较,同时指出这种变化对光栅效率的影响可以进行补偿.

A model describing the propagation of optical weve in a hologram volume grating is studied. Then the effect of the change in the average permittivity of the grating on diffraction efficiency is discussed. Finally a Comparision of the results of this model with those by Solymar is made. The author comes to a conclusion that the effect of the change on the diffraction cffieency can be compensated.
