Abstract:

Dynamic multiple scattering of laser radiation in a concentrated suspension of micron or submicron particles is considered with the allowance for particle acceleration in the field of (a) other (accelerating) laser beam and (b) probing radiation. It is shown that in both of the cases the methods of optical correlation spectroscopy allow estimation of the velocity of light-induced particle motion to be made by analyzing time autocorrelation function of the multiply scattered radiation. The method is proposed to measure the characteristic velocities of light-induced particle flows based on the principles of diffusion-wave spectroscopy.
