PECULIARITIES OF REFLECTION HOLOGRAPHIC GRATING FOR¬MATION IN PHOTOPOLYMERS AT TWO WAVE IN¬TERACTION AND SMALL CONTRAST // Tomsk State Pedagogical University Bulletin. 2005. Issue 7 (51). P. 72-76

In the work we present the model of reflection holo¬graphic grating formation in photopolymers at two wave mixing and small contrast, optional non linearity of pho-topolymerization and optional ratio of polymerization and diffusion mechanisms of record. It have been shown essential space-time transformation of amplitude -phase profile of first harmonic and diffraction properties of reflection holographic grating.

NON LINEAR MODEL OF HOLOGRAPHIC REFLECTION GRATING FORMATION IN ABSORBENT POTOPOLYMERS // Tomsk State Pedagogical University Bulletin. 2005. Issue 7 (51). P. 77-83

We present the results of theoretical investigation of record and readout of holographic reflection gratings in absorbent photopolymers with dye sensitizer with taking into consideration of high order spatial harmonics and self-diffraction. The analytical model for description of time-spatial field of holographic grating during record process with taking into account of absorption and diffu¬sion processes has been created.
