EN In this work, we present the structure of a system based on several optoelectronic sensors used for noninvasive monitoring of local changes in the arterial blood pulse waveform. The phenomena accompanying the acquisition of optical signals from biological objects were analyzed. Reflectance optoelectronic sensors, photoplethysmographic signal conditioning and acquisition system were designed and constructed. Sample time curves of the signals obtained have been presented. The presented set expands the possibilities of the analysis based on the measuring data from several sensors placed in various points of human body.
