Abstract
A device for the line-by-line electrical analysis of an image. It comprises a piezo-electric medium associated with a semiconductor medium scanned by the interaction of two elastic waves propagated at the surface of the piezoelectric medium, and an electrode network. The electrodes are disposed on the semiconductor medium parallel to the scanning direction and each of which supplies an electrical signal the amplitude of which characterizes the luminous intensity of the elementary zones of the image.
