ABSTRACT:
A device for reading two-dimensional optical images. It comprises a piezoelectric substrate on which two transducers transmit elastic waves in two separate directions, and a semiconductive and photoconductive layer arranged near the surface of the substrate, in which a nonlinear interaction occurs opposite the point where the two said directions converge. This point of convergence forms a reading point of the image which is projected onto the photoconductor, this point moving as a function of time along a straight line which forms an analysis line of said image.
