Optimization in the miniaturized optical holographic storage system

In this paper, the geometric configuration of recording beams and the orientation of crystal axis is optimized for optical holographic storage in order to achieve the preferable effective dynamic range and angle selectivity simultaneity. The influences of the defocusing amount of record crystal on data retrieval in the Fourier transform configuration are studied theoretically. The field lens is used in the optical path for Fourier transform to reduce the length of optical path and the distortion. T he optimization results are used to design the optical architecture for miniaturizing the optical holographic storage system.
