Abstract : The effect of presensitizing the high resolution photographic plates used to record holograms was experimentally investigated. Presensitization consisted in exposing the plate to a uniform exposure by a small quantity of light such that the sites within the emulsion are exposed to the threshold of developability. The experimental procedure consisted of comparing virtual holographic image luminance for pre-exposed holograms and not pre-exposed holograms. Readings were taken through various portions of the hologram plate as well as at various angular orientations. Results indicate that brighter images as well as 'cleaner' plates result from presensitization. All luminance measurements were made with a Spectra-Pritchard Photometer. (Author)
