Study of multiple record of the optical information on photothermoplastic mediums (PTPM) in the holographic way

摘要

In the given work results of experiments on carrying out of cyclic record on PTPM are resulted by holographic way. The optical scheme is resulted, allowing automating process of record of elementary holograms in the form of diffraction gratings on PTPM and their definitions diffraction efficiency. The mechanism of occurrence of "parasitic" memory PTPM due to photostructural transformations into thin layers CGS is considered.
