The possibility of the reconstruction of a complex non-harmonic function of the moving object by means of autodyne interference system is represented in this work. The results of the experiment show the possibility to determine the parameters of complex nonharmonic movements of the reflector. It is obvious that the use of multistage digital filtering in the course of autodyne experiment allows us to reduce the influence of the noise distortion on restored signal.

The possibility of using wavelet transforms for reconstruction of complex nonperiodic motion in optical homodyne in-terferometrie is presented. The numerical simulation of object motion function reconstruction using Fourier and wavelet transforms is performed, and results comparative analysis is examined.
Simulation of irreversible growth in 3D lattices consisting of filled and release cells with certain number of interconnections was carried out. Results of simulations are suggested to use for interpretation of the behavior of dynamic speckles induced by laser light scattering in non- stationary porous media.
