holographic grating

基本解释

PDLC volume holographic grating has much higher diffraction efficiency than normal grating, because it can focus the diffraction light to the non zero band.
PDLC体全息光栅可使光栅的衍射能量集中到非零级的衍射级次上，大大提高衍射效率。
Furthermore, the paper offers the error limited of these parameters and they are good to guide practical fabrication of the volume phase holographic grating.
同时，本文还计算出了这几种参数的误差容限，这对体积相位全息光栅的实际制作具有指导作用。
First, the properties of volume holographic grating, such as diffraction efficiencies, angle and wavelength selectivity, have been theoretically analyzed by using the couple-wave theory.
首先应用耦合波理论对体全息光栅的衍射效率以及角度选择性和波长选择性等衍射特性进行了分析。
