Abstract

In many optical recognition processes a multiple filters synthesis is required. These filters are usually computer generated holograms in which it is possible to codify different objects to be detected and eventually someone to be refused. In most cases the codification of all this information in binary media produces filters with low light efficiency due to the amount of dark zones, which imposes a practical limit to the amount of information to be codified. Synthesis of composed filters in color photographic films by using a polychromatic source, would allow us to increase the capacity to storage information.
