Abstract
The PMMA material doped with high content of PQ is fabricated in our Lab. Dynamic range is studied to be 2.5mm'' by peristrophic multiplexing. In Angular multiplexing based on rotating material, 100 frames of gray image are recorded in a 1 mm thick sample and the reproduced images have a good quality. The storage capacity is calculated to be 3.1 X 10 9 bits/cm', which implies that our PQ/PMMA material is suitable for volume holographic storage. The intensity of grating increases with time and the shift of sensitivity angle, which is about 0.1375 deg for each multiplexing image in reproduced process, are also found. We give a qualitative analysis from the aspect of dark reaction of sample.
