Paper Abstract

We describe a practical approach to 2D image storage in a coherent time-domain optical memory, which can be readily implemented with existing technologies. In this approach, images are stored spectroholographically in narrow (< 1 MHz) frequency channels of a time-domain storage material, with one image per channel. Advantages of this approach include fast single-frame recording time, variable playback speeds, random frame access, and the ability to perform in-memory image processing. Experimental results demonstrating high- resolution, high-fidelity, single-channel image storage with the use of a low-power, single- frequency ring laser are presented.
