Paper Abstract
The phenomenon of laser speckle can be used for detection and visualization of physical or biological activity in various
objects (e.g. fruits, seeds, coatings) through statistical description of speckle dynamics. The paper presents the results of
non-destructive monitoring of bread cooling by co-occurrence matrix and temporal structure function analysis of speckle
patterns which have been recorded continuously within a few days. In total, 72960 and 39680 images were recorded and
processed for two similar bread samples respectively. The experiments proved the expected steep decrease of activity
related to the processes in the bread samples during the first several hours and revealed its oscillating character within
the next few days. Characterization of activity over the bread sample surface was also obtained.
