A prototype reflective spatial light modulator (SLM) system has been developed for writing megabit pages of data into a holographic medium at a rate of 12 pages per minute. The SLM is based upon a crystalline-silicon reflective active-matrix array with integrated data drivers, using liquid crystal (LC) electrooptics and a personal computer system with an interface to provide data. The LC has been optimized for high contrast and efficiency with coherent illumination. The resolution-limited… Expand


Modulation coding for pixel-matched holographic data storage.
A digital holographic storage system for the study of noise sources and the evaluation of modulation and error-correction codes, which permits image transmission down to signal levels of ~2000 photons per ON camera pixel, at raw bit-error rates of better than 10(-5). Expand
