Abstract: A flexible disc is provided on at least one face of which an image is recorded along a spiral track in heliographic form. Under the action of a monochromatic light beam this image is obtained as a floating image. An arrangement is provided for playing back such discs. The invention is particularly applicable to television.

Abstract: The present invention relates to data-processing systems based upon the diffraction properties of a coherent radiation near a focus. The data-processing system in accordance with the invention comprises at least one ultrasonic tank containing a fluid wherein coherent ultrasonic radiation propagates; this tank contains a modulating object on which there are transcribed the data being processed; ultrasonic focussing means provides by means of a Fourier transform the spatial frequency spectrum of said object.
