Abstract
967, 818. Playing back optical records. FRANZ MORAT G.m.b.H. May 9, 1963 [June, 29 1962], No. 18461/63. Heading G5R. The centre portion 3 of a driving or stabilizing sprocket forms the rotating cylindrical lens supporting a multiple-track optical film 11, while at the same time focussing light from a lamp 5 on to the adjacent slit 4. A condensing lens 1 is followed by a cylindrical lens 2 to bring the line-filament 5a to a point focus. A two-dimensional matrix of photo-diodes 15 are connected by light-pipes 16 whose ends are arranged in a single line at the slit 4. In a modification, the light is focused at the film and the slit dispensed with. When used for stabilizing, the sprocket teeth prevent the film from rubbing against the lens 3 during running up to speed or stopping.
