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-holograms 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. Experimental results demonstrating the possibility of a linear case of diffraction efficiency growth in time on the PTPM allowing increase of the time of surface relief development and the value of holograms diffraction efficiency are shown. Also, the process of local multiplexed holograms recording on the PTPM by the developed method is studied. Using the developed simultaneous method there were recorded two-dimensional fourier-holograms in step-by-step procedure on the PTP-disk carrier. The possibility of holographic PTP-disk based data storage realization is discussed.
