Latent holographic image dynamics in the dichromated gelatin films

Holographic recording medium on basis of dichromated gelatin layers is example of complex nonlinear system. Layers optical parameters such as diffracted efficiency or modulation transfer function are nonlinear in the time or energy dependence under constant intensity of laser irradiation. To research latent image optical parameter behavior we have to divide our systems to same subsystems, each of them works on own frequency and give the contribution to general dynamics of a system. This paper is devoted to using of wavelet-analysis to reveal frequency - temporary characteristics. Similar analyses allow selecting main parameters of subsystems and to control of systems dynamics in order to achieve certain results.
