Speckle techniques for blood microcirculation monitoring at paradontitis treatment

Results of Monte-Carlo simulations of Doppler shift are presented for model of random medium that containing moving particles. The single-layered and two-layered configurations of the medium are considered. Doppler shift of the frequency of incident laser light is investigated as a function of such parameters as absorption coefficient, scattering coefficient, and thickness of the medium. Possibility of application of speckle interferometry for diagnostics in dentistry have been analyzed. Problem of standardization of the measurement procedure have been studied. Algorithm of processing of Doppler signal in the diagnostics of blood microcirculation in mucous membrane have been suggested.
