Beaded plate recording of integral photographs

The beaded plate is a simple inexpensive medium for recording integral photographs. It consists of a monolayer of glass balls laid down on a photographic emulsion. The preparation of beaded plates is described. The beaded plate is exposed in the central plane of a pseudoscopic real image reconstructed from a hologram or an integral photograph. When the beaded plate is developed in reversal and illuminated from the rear, a three-dimensional image is produced. Experimental results are given and some of the problems are discussed.
