Abstract

ASM method is an effective method for disk-type photopolymer high-density holographic storage that has a limited medium thickness. In this paper, the effects of recording angles of ASM method disk-type photopolymer high-density holographic storage on the recording capacity and density are studied theoretically. The calculation and analysis show that the recording density and capacity depend on the recording angles critically whether the spherical wave beam or plane wave beam is used as the reference beam. The results show that no matter spherical wave or plane wave is used as the reference beam the recording density and capacity increases monotonously with the increase of θ_s when θ_R is fixed. When the recording angle between two recording beams is large, it has an optimal incidence angle of reference beam to get the maximum recording density and capacity. By using this optimal recording angle we can get 3 - 4 times improvmeent of recording density and capacity.
