摘要

Dynamic optical reconstruction of digital binary holograms projected on optically addressed liquid crystal spatial light modulators with the use of computer driven multimedia projector is described. The high spatial resolution, sensitivity and full reversibility of manufactured spatial light modulators is achieved by the use of photoconducting PVK:TNF polymer layer serving as a transducer of incoming light intensity pattern into modulation of refractive index inside adjacent LC layer. Linearly polarized laser light reconstructs the phase holograms at the video-rate. The advantages and drawbacks of the presented system are discussed.
