The main factors influencing the diffraction efficiency of holographic polymer dispersed liquid crystal (HPDLC) were studied. The dependence of diffraction efficiency on the choice of polymer monomer, exposure intensity, exposure time, liquid crystal content and temperature was analyzed to find the optimal conditions for The diffraction characteristic is optimized.The maximum diffraction efficiency measured to date is 80 2% .The surface morphology of HPDLC was also studied under the scanning electron microscope (SEM)
