Abstract

1342476 Holograms; motion pictures HOLOTRON CORP 3 Dec 1970 [11 Dec 1969 (2)] 57389/70 Heading G2J In hologram construction each distinct piece of two-dimensional information occupies an independant hologram surface and a converging information beam forms a hologram having an area significantly smaller than the twodimensional extent of the information. The reference beam is perpendicular to the record surface. Various means of improving definition are disclosed. Copy holograms may be made by shining a collimated beam through the hologram and allowing an undiffracted portion thereof to interfere with the signal beam at the surface of a second record stationary with respect to the first. A motion picture may be so recorded and the sound may be holographically recorded in the same sound medium.
