Abstract: The present invention relates to a novel optical approach based on spatial analysis of spatial laser speckle patterns for tissue in-depth flow inspection characteristics. In particular, the invention relates to a technique for determining flow characteristics and identifying low blood flow or a blockage in blood vessels.

Abstract: A system for use in monitoring application is described. The system comprises a light detection unit and an illumination arrangement. The detection unit is configured for collecting light returning from a selected inspection region for determining variations in collected light intensity. The illumination arrangement comprises one or more light sources configured for providing illumination of a selected wavelength range directed toward said inspection region. Wherein the illumination arrangement is arranged around the detection unit to provide symmetrical illumination conditions with respect to an axis connecting said detection unit and said inspection region.
