Abstract
Phase holograms processed with a reversal bleaching is considered to have lower diffraction efficiency than those processed with other bleaching methods. The high diffraction efficiency could also be obtained in the reversal bleach under the adjustment of developer component. This paper shows that must have been optimized the type and the concentration of developer component in order to obtain the high diffraction efficiency. Experiments were carried out with Slavich PFG-01 plates on the processing of transmission holograms and the four types developer used with reversal bleach. The developer is composed of 1-ascorbic acid, metol, phenidone, and sodium carbonate contained with different amounts. The maximum diffraction efficiency of 89% was obtained.
