| Abstract: | H PDLC volume holographic grating has much higher diffraction efficiency than normal grating, because it can focus the diffraction light to the non zero band. We have conducted some experiments to investigate the major factors which impact the diffraction efficiency of grating, namely different recipes of PDLC, the degree of two laser beams, thickness of film, exposing time of PDLC cells. |

| Keywords: | volume holographic grating polymer dispersed liquid crystal diffraction efficiency |
