Abstract
The process of local holograms recording on organic photothermoplastic (PTP) materials and the influence of their characteristics on the quality of registration are investigated. The original simultaneous method of the local holographic recording on the PTP materials by IR-laser heating supplying qualitative Fourier-hologram recording of the analog and digital information is described. The usual simultaneous method of PTP-recording is characterized by exponential growth of diffraction efficiency in time. The possibility of a linear case of diffraction efficiency growth in time on the PTPM allowing the increase of both the time of surface relief development and the value of hologram diffraction efficiency is shown. The approach for the holograms recording on the PTP-disk in automatic regime allowing stabilization of their characteristics is suggested. Also, the process of local multiplexed holograms recording on the PTPM by the developed method is studied. Using the developed simultaneous method two-dimensional Fourier-holograms were recorded in step-by-step procedure on the PTP-disk carrier. The possibility of the holographic PTP-disk based data storage realization is discussed.
