Paper Abstract

Methylene blue sensitized dichromated gelatin (MBDCG) is a suitable recording material for full color hologram in a single layer. Such a hologram has the possibility of being used as the advanced display devices and optical elements. However, the process of drying in an ammonia atmosphere is necessary for making the MBDCG. This process is troublesome and instable. A new method for preparing the MBDCG has been developed. The sensitized solution is composed of MB, ammonium dichromate, and gelatin in alkaline state. The MBDCG does not need to dry in an ammonia atmosphere when the concentration of MB and ammonium dichromate is properly controlled. The limits of the most suitable concentration of these agents are studied. Some experimental results of Lippmann color holograms using this MBDCG are presented.
