Laser Speckle Analysis for Microcirculation Depth Proﬁling (FCT 01238/2013/CP1155/CT0004)
The goal of the project was to demonstrate the feasibility of a laser speckle contrast imaging (LSCI) technique by using multiple wavelength light sources (visible and NIR) and therefore introduce a new degree of freedom, i.e. the depth discrimination, in the assessment of microvascular perfusion on skin tissue.
The main working steps on this project were the assembly of a skin like phantom able to reproduce scatterers flow at different depths, the construction of an optical testbench prototype with both the laser light sources and image acquisition hardware and the data processing workstation, and finally, the development of a set of algorithms for speckle pattern analysis targeting depth profiling of the flow on the sample phantom.
