Optical holographic memory using angular-rotationally phase-coded multiplexing in a LiNbO3:Fe crystal

Applied Physics B Aims and scope Submit manuscript

Abstract.

We propose a new holographic memory scheme based on random-phase-coded multiplexing in a photorefractive LiNbO3:Fe crystal. Experimental results show that rotating a diffuser placed as a random-phase modulator in the path of the reference beam provides a simple yet effective method of increasing the holographic storage capabilities of the crystal. Combining this rotational multiplexing with angular multiplexing offers further data-storage possibilities. The advantage of using post-image versus pre-image phase modulation of the object beam is demonstrated.
