Abstract: In this paper, we show that laser speckle pattern provides useful information toward revealing discrimination between nanofibers and membranes. Chitosan materials particularly organosoluble chitosan derivatives have a number of applications. The surface characteristics of these… read more here.

Abstract: Abstract Pointwise intensity-based algorithms are the most popular algorithms in dynamic laser speckle measurement of physical or biological activity. The output of this measurement is a two-dimensional map which qualitatively separates regions of higher or… read more here.

DOI: 10.1016/j.optlastec.2020.106221
Abstract: Abstract We analyse how the frequency bands influence the independence of speckle index values from the level of illumination in a dynamic laser speckle analysis. Specifically, we study how the temporal speckle deviation index is… read more here.
