“…To process the obtained signals, we calculate the normalized autocorrelation function of the intensity fluctuations of the scattered light. The correlation function in the case of blood microcirculation detection, where the scatterer is erythrocytes in the bloodstream, is described by the following expression [ 18 ]: where ϑ is the speed of the scatterer, l is the distance from the scattering object to the photodetector, is wavelength of light from the light source, , and are z-dependent width and curvature of the wave front of the beam. We denote by K the proportionality coefficient determined by the parameters of the optical circuit: where .…”

“…When diagnosing vascular function in pregnancy, it is important first and foremost to consider maternal and fetal safety, so the use of safe and noninvasive diagnostic methods is preferable. The best prospects in this aspect are presented by methods of biophotonics [4,5]. Endothelial dysfunction seen in the skin of patients with type 1 DM is known to precede the development of target organ microcirculatory disorders.…”
