Velocity measurement by first order statistics of time-differentiated laser speckles

Abstract This paper describes a new and very simple technique for the measurement of mean velocities of moving scatterers. Both, basic statistics and experimental results are presented for the velocimetry of scattering objects by the variance of the time-derivative of the intensity in the speckle field.
