High-density high-speed holographic memory for T&E of next-generation embedded instrumentation weapon systems

摘要

Massively parallel "onboard" storage technologies for high-density and high-speed recording/retrieval of data from both weapons systems and test instrumentation are needed to improve the test and evaluation process of many of today's smart weapons systems. This will be accomplished by dramatically increasing the amount of available data that are necessary to perform comprehensive systems analysis. An innovative holographic memory system has been developed at the Jet Propulsion Laboratory, Pasadena, California, for high-density and high-speed data storage for stressing environments. This paper discusses the development and technical progress of a system utilizing a newly developed electro-optic beam-steering technology to achieve a design goal of greater than 250 Gbs of storage in a cubic photo-refractive crystal with up to 1 Gbs-per-second transfer rate. A compact disc-size holographic memory breadboard was recently developed and demonstrated for holographic data storage and retrieval.
