Abstract
Application of the quartz-plate Sokolov image converter to real-time acoustical holography is benefited by a larger aperture than is available in older designs. A circular aperture of 2 in. diameter (3.14 in.2) is the largest size that has been available for frequencies above 1 MHz. The reasons behind this limit and the desirability of a larger aperture for acoustical holography have been investigated. Two designs for image converters have been completed which offer practical apertures of 100 in.2 or greater at frequencies up to approximately 20 MHz. An image converter was constructed from one such design with a 16-in.2 square aperture operating at 2 MHz. Details of the tube and some Gabor holograms produced with it are described. The limitations on increasing converter aperture by these means are discussed.
