On the real-time reconstruction of digital holograms displayed on photosensitive liquid crystal systems

Dynamic optical reconstruction of digital binary holograms projected on optically addressed liquid crystal spatial light modulators with the use of a computer driven multimedia projector is described. A high spatial resolution, sensitivity and full reversibility of the manufactured spatial light modulators are achieved by the use of a photoconducting PVK:TNF polymer layer serving as a transducer of incoming light intensity pattern into modulation of refractive index inside the 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.
