Method of and apparatus for forming volume type phase hologram |
| abstract |
A method of forming a volume type phase hologram comprises the steps of, after exposure of a holographic material comprising a polymeric matrix having a radiation active substance associated therewith to an interference pattern of radiation, dipping the pattern-wise exposed holographic material in a swelling solution consisting of a first solvent which can act as a good solvent for the polymer of the matrix and a second solvent which can act as a poor solvent for the polymer and has a higher boiling point than that of the first solvent, and then pulling the swollen holographic material up from the swelling solution, whereby unifornly developed holograms having a large size and high qualities can be easily produced by a simple production process. An apparatus for carrying out the method is also disclosed. |
