Abstract
A system is provided for reading acoustic images such as those obtainable in an elastic medium as a result of the focusing of, or interference between, acoustic waves. The image analysing device comprises a substrate made of piezoelectric material which is provided on one face with an interdigital array and an electro-acoustic transducer. The system permits to read acoustic images formed at the free surface on the opposite face of the substrate or at a certain distance from its free surface in contact with an elastic propagation medium.
