ABSTRACT:
This invention concerns a process for producing diffracting phase structures in an interaction medium, which is formed of microballs of material in suspension in a polymerizable liquid. When illumination rings have been recorded by the interference of two light waves, they are fixed in situ by exposing the mixture to ultraviolet radiation.
