ABSTRACT:
A reflection hologram is recorded in a photosensitive film on a substrate held in a support by interference between an illuminating beam and its return from a back reflector. A scanning device moves the beam from a laser angularly about a fixed apparent beam source position which remains stationary relative to the film to give improved hologram formation with the back reflector spaced from the film.
