Abstract

149,207. Mylo, R., (Assignee of Lenczycki, M.). Nov. 10, 1915, [Convention date]. Optical apparatus ; optical records. -- A beam of light controlled by sound-waves forms a photographic record of fixed dimensions but of varying intensity. The beam passes through a light-transmitting body a enclosed in an opaque sleeve d provided on each side with slits covered with ground glass. A shutter e cuts off diffraction rays, and an image of the slit on the sleeve d is formed by a lens f on a moving plate or film g. Several beams may be used at once, a corresponding number of slits being provided.
