description: The given work is devoted to the development of a small-sized speckle-correlation sensor of blood flow velocity in microcapillaries. This sensor allows you to noninvasively determine the speed of blood flow in the microcirculatory bed. The aim of the work is to develop a small-sized sensor for the study of blood flow velocity. In this paper, a literary review of methods for studying blood flow velocity is carried out, the choice of speckle correlation analysis for estimating blood flow velocity in microcapillaries is justified. The physical principles of the speckle-correlation method are analyzed, and the mathematical principles are investigated. Every component included in the sensor is justified.To establish the applicability and effectiveness of the sensor, experiments were conducted on a developed test object simulating a capillary along with blood flow. And, on conditionally healthy volunteers in various conditions of the experiment. The results of these studies show that this sensor can be used in the diagnosis of cardiovascular diseases and applied in clinical medicine.
