Abstract
There is provided a simple method and means for recording in any single-emulsion photographic film or plate an optical transparency which independently controls both the amplitude and the phase of the transmitted light at each transverse coordinate of the transparency according to predetermined spatial patterns. The phase and amplitude information are recorded at separate levels within the emulsion.
