Abstract

We present preliminary results on diffraction gratings made with holographic techniques using dichromated gelatin (DCG) matrix with edible dyes, the purple red, Layar^® and blue Sabofrut^®. The gratings were recorded with a laser diode, λ = 530nm. Curves show diffracted intensity vs exposure time. The recorded gratings show different diffraction efficiencies of gratings prepared with DCG, purple red + DCG, and blue+ DCG. We observed high diffraction efficiency with purple red. All exposure conditions and reconstruction were therefor for all gratings with the same concentration of dichromate for each one of the photosensitive emulsions prepared.
