METHOD OF AND APPARATUS FOR PRODUCING HOLOGRAMS

摘要

A method of and apparatus for producing holographs in which a pulsed laser is used emitting a pulse duration of between 8 and 350 nanoseconds and intermittently or continuously moving a film of laser light sensitive material passed an aperture through which the laser light passes so that a subject which may be an object or preferably a subject hologram located adjacent the aperture may produce holograms on successive portions of the film.
