REAL‐TIME HOLOGRAPHIC RECONSTRUCTION BY ELECTRO‐OPTIC MODULATION

Light modulation by an electro‐optical material is under examination as an approach to real‐time display for sampled holograms. The feasibility of obtaining reconstructed images from coherent light transmitted through a deuterated KH2PO4 crystal (DKDP) having a holographic charge pattern has been demonstrated. A special advantage in the image‐to‐back‐ground intensity ratio, factors influencing resolution, and problems peculiar to the use of DKDP are discussed.
