description: Due to the growing prevalence of cardiovascular diseases, much attention is being paid to the development of cardio diagnostic methods for detecting pathologies in the early stages. A special place among the diagnostic equipment is occupied by optical sensors, which allow non-invasive examination of the patient. There are various methods of signal analysis and processing in optical devices, one of them is the speckle correlation method. The method is based on the use of the autocorrelation function of the values of the scattered radiation intensity, which determines the value of the blood flow velocity in the microcirculatory bed. The purpose of this work is to develop a software algorithm for processing the signal from an optical blood flow velocity sensor based on the speckle correlation method. To achieve this goal, a literature review was conducted on the methods and algorithms of signal processing in the study of the blood microcirculation system, the theoretical foundations of speckle correlation analysis were studied, and a software algorithm for processing the signal coming from the photodetector was proposed. Based on the results obtained in the experiments, we can conclude that the proposed algorithm for processing the biological signal is applicable in medical diagnostics.
