A novel polarized-type phase Doppler method is proposed for measurements of the absorption coefficient as well as size and velocity of moving particles. The particle diameter is obtained from the phase difference between the reflected and refracted rays separately detected in a single scattering direction by using the polarization technique, while the absorption coefficient can be determined from the intensity ratio of reflected and refracted components in a single burst of Doppler beat signals. We numerically estimated the accuracy in measurements of the absorption coefficient in relation to some optical conditions such as the beam waist diameter and the direction in which the photodetector is located.
