Statistical processing of speckle data enables observation of the speed of processes. In intensity-based pointwise dynamic speckle analysis, a map related to speed’s spatial distribution is extracted from a sequence of speckle patterns formed on an

Photoinduced supramolecular chiral structures in azo materials have been extensively studied for the development of all-optical switches and because of their influence on the properties of certain types of polarization holographic gratings. Here, we

Industrial inspection of processes by capture of speckle patterns often requires detection of a small activity area buried in a background. This work presents analysis of sensitivity of the dynamic speckle method by processing simulated and experimen
