A method capable of measuring blood flow at precise depths within the skin is described. The method determines the static and the dynamic properties of light that is backscattered to small areas on the surface of the skin at several contiguous locations along the expected trajectory of laser-light propagation. From observations the method has been shown to be capable of determining physical characteristics that are unique to the different layers of the skin.
