Abstract

We suggest a method for quantitative determination of the total fraction of Doppler-shifted photons in light scattered by an object containing both moving and static scatterers. The method is based on two approaches: time-varying speckle and laser Doppler were we consider the speckle fluctuations as the primary phenomenon with the Doppler effect being the main cause of these fluctuations. A validation of the method and one of its practical applications is demonstrated. The total fraction of Doppler-shifted photons in light backscattered from human skin has been measured in vivo.
