The aim of the work was to explore the capabilities of LDF method in studying the human skin blood and lymph microcirculation. Materials and methods. It was assumed that analyzing LDF signals in different frequency ranges of the Doppler shift allows the evaluation of the motion of various scattering particles. Results and discussion. When conducting functional tests, the reverse reaction of the microcirculation index in the low frequency ranges was observed in comparison with the high-frequency ones. Additional differences were obtained in the wavelet analysis of LDF signals. Conclusions. The proposed approach with division into frequency ranges proved useful in the joint study of microhemo- and lymphocirculation.
