Abstract

Multicolor image reconstruction from holograms behaving as two-dimensional media suffer severely from overlap of the similarly structured crosstalk images unless special techniques are used in formation. This paper describes examples of two techniques which eliminate the crosstalk images. The first technique involves nonoverlapping spatial multiplexing and is illustrated by interlacing on the hologram the colored images of a mask placed in the reference beam. The second technique involves coding the reference beam so that each colored reference wave varies in a unique manner over the hologram plate. Photographs of the resulting multicolor reconstructions are shown.
