1 | 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. | 1018 | ||||
2 | 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. | 932 |
