| 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 influenced by the use of three different frequency bands of the speckle signal. Finally, it is shown how signals with high frequency components return values with greater independence of the level of illumination. |
