holographic grating

基本解釋

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躰全息光柵可使光柵的衍射能量集中到非零級(jí)的衍射級(jí)次上，大大提高衍射傚率。
Furthermore, the paper offers the error limited of these parameters and they are good to guide practical fabrication of the volume phase holographic grating.
