Study of signals from dynamic speckle patterns

In study of dynamic processes, information on parameters of system can be obtained from the changes in corresponding dynamic speckle pattern. Examples of these processes are biological, chemical or biochemical reactions, changes in molecular populations, changes in absorption, reflection properties or refraction index of a medium, superficial dynamics process, crystal dissolution, particle movement and others. In the present work the generation and counting of pulses corresponding to signals obtained from dynamic speckle patterns, and a study of some signal processing methods, in particular the analysis of pseudo-phase portrait are shown.
