We studied energy coupling between gratings and angularly multiplexed 20 gratings with a uniform diffraction efficiency within 25 im layer thickness of dichromated gelatin. The dependence of diffraction efficiency on beam ratio is given. We recorded a matrix form memory of nxmxp elements, where n and m are the rows and columns and p the number of multiplexes. For indication only, n=m=1O, p=2O, the surface area of the matrix is 1 cm2. Color diffractive images and digital data are illustrated as well as video, cartography and medical applications.
