Skin blood microcirculation probing: experiments and theoretical remarks

Photon correlation technique and standard optical reflectance spectroscopy are used for the in vivo monitoring of skin blood microcirculation. We undertook the experiments to establish the effect of mechanical pressure of the probe on the skin surface. We have presented the results of experiments that, we believe, will contribute the understanding of in vivo clinical measurements of skin blood microcirculation. We show that even minimal mechanical pressure on the skin surface produced by a probe affects skin blood microcirculation and the result of its in vivo measurements, respectively. To analyze skin blood microcirculations we propose to use the photon correlation technique extended for the transition regime of scattering from single to multiple.
