Abstract
For multihologram recording, especially in a disk-shaped storage medium, a simple cost-effective method to implement the peristrophic, angular, and spatial multiplexing techniques together is studied and its experimental demonstration is presented. Holographic storage with both peristrophic and angular multiplexing is realized by controlling the reference beam directly with a pair of wedge prisms, while the storage with spatial multiplexing is achieved by shifting the storage medium. The area storage density of our system is strongly dependent on the f numbers of the lenses in the signal and reference arms. For a given f number of the lens in the reference arm, we show that the area storage density becomes maximal when the f number of the lens in the signal arm is approximately twice that in the reference arm. The proposed method can be used for 3-D holographic disk memories to enhance their area storage density.
