An acousto-electrical device for storing and processing information, in analog form, at any point of a two dimensional surface. It comprises: a piezoelectric substrate carrying four electro-mechanical transducers emitting elastic surface waves in two normal directions; a semi-conductor substrate carrying a diode network placed facing the piezoelectric substrate, and two electrodes placed respectively on the end faces of the two substrates. In one embodiment, the storing of a signal applied between the electrodes is achieved by means of two elastic auxiliary addressing waves, the non linear interaction of these three signals supplying a spatially periodic signal independent of time which is stored by the diodes. The stored signal is subsequently processed by means of elastic reading waves which interact non linearly therewith to provide simple reading of the initial signal or processing thereof, in particular its Fourier transform. |
