Abstract

An experimental study to ascertain the recornbination action of zinic chloride ZnC1) and triethanolarnjne(TEA) on improving photosensitivity in rnethylene blue sensitized dichrornated gelatin(MBDCG) holograms has been carried out. The required unslanted volunie holographic transmission gratings in MBDCG have been recorded using 633nm light from a He— Ne laser. The experiments show three important results: First, the ZnCI and TEA have great recombination action on the photosensitivity of MBDCG. Next, the diffraction efficiency vs light exposure energy graph is bell—shaped. Last, the maximum diffraction efficiency reaches 83 under 200rnj/ctn2 of light exposure. Keywords: volume hoigratu, diffraction efficiency, dichrotaated gelatins red- sensitive hoigraphic uaierial, photosensitivity, modulation of refractive iadex, holographic transuission grating.
