Paper Abstract

The monomer state methylene blue (MB) dye plays a major role as a sensitizer in methylene blue sensitized dichromated gelatin (MBDCG). The dimer state of the MB can be reduced significantly by controlling the concentration of the MB, the chromium and the water in the gelatin. The authors achieved over 80% transmittance of the MBDCG plate for red light without sacrificing the sensitivity. Some experimental results of full color holograms recorded by the single beam Lippmann method (Denisyuk configuration) are presented.
