Spatial frequency study of holograms with albumins material

We present the analysis of holographic recording in photosensitive films using albumin matrixs: gallus gallus and Callipepla cali , exposed to a λ=442nm, with ammonium dichromate, (NH 4 ) 2 Cr 2 O 7 , as a photo-oxidant agent. These simultaneously were performed holographic diffraction gratings with different spatial frequencies. Getting high diffraction efficiencies of holographic gratings as a function of spatial frequency (lines/mm), known as modulo of the transfer function (MTF). We made a comparison of the experimental results between the different bird albumins.
