Speckle-Interferometry For Analysis Of Blood Microcirculation In Dentistry

The results of statistical analysis of spectra of intensity fluctuation of light, scattered from oral cavity membrane and teeth pulp, are presented. The dependence of the spectral moments of speckle-interferometric signal on the cutoff frequency is investigated. Influence of own noise of measuring system on formation of speckle-interferometric signal is studied. Dependencies of scattering properties of biotissue on characteristics of speckle interferometric and Doppler signals are analyzed. New algorithms to statistical processing of measuring are suggested.
