Photopolymer (PP) was an attractive holographic material for data storage, information processing and display application. Recently, we prepared new PP system that shows quite high diffraction efficiency achieved by the two-beam interference method. The diffraction properties of the gratings fabricated in our photopolymer systems were investigated by real-time optical recording. The holographic performance was characterized by recording multiple-hologram in the materials. The angular response of the probe beam with R,G,B wavelength was observed by optimizing the accurate Bragg angle rotating the sample in 0.5o for each measurement. The potential for holographic diffuser and holographic color filter were illustrated using the newly prepared photopolymers. |
