Abstract

A method for recording high efficiency multiplexed reflection holograms has been discussed. The image diffraction efficiency of reflection holograms has been enhanced by recording hologram of a real image of the object projected by another master off-axis hologram whose effective aperture is limited by a suitably shaped stop. The limited viewing area offered by these holograms is gainfully exploited for incoherent multiplexing of several objects on same recording plate. A technique for multiplexing reflection holograms is presented where the well known property of mirror like behaviour of interfering fringes is used. Two schemes of horizontal and vertical plane multiplexing have been discussed where the different multiplexed images do not overlap in the final viewing. Optimization of different experimental parameters to compensate for holographic reciprocity law failure and to achieve uniform diffraction efficiency in multiplexed restricted aperture reflection holograms has also been carried out.
