Lippmann color holograms recorded in methylene-blue-sensitized dichromated gelatin

Abstract

Experimental techniques are described for recording Lippmann color holograms in methylene-blue-sensitized dichromated gelatin. 458-, 488-, and 514.5-nm light from an argon laser and 633-nm light from a He-Ne laser are used to record the holograms. Data on the diffraction efficiency and wavelength selectivity are presented.
