Abstract

We show that the possibility of storing more informations within a decreased volume is now opened. This is due mainly to the recording material we have used which is an improved polypeptide of dichromated gelatin. The input digital information is recorded and a diffractive digital image is reconstructed. The percentage of pixels error detection is less than 1% when decoded. We recorded a matrix form memory of n×m×p where n and m are rows and columns of the matrix and p the number of multiplexes. In this paper n=m=10 and p=20, for a 25 μm thickness of the recorded medium. The diffraction efficiency uniformity is demonstrated
