摘要： A highly informative methodology, the essence of which is to obtain the parameters of an object under study by means of the data synchronous acquisition from several measurement channels, predominantly based on different physical principles, infrared thermography (IRT) as a leading research tool included in such a multichannel (multimodal) measuring system is considered in some detail. The IRT-aided multichannel approach is demonstrated with studying the physiological characteristics in humans. The measurement synchronism of different technical means is realized by the computerization and automation of the experiment. The programmable microcontroller ESP32 served as main operating and readout unit. With a time resolution of 100-200 measurements per second, the experimental data were obtained. It made it possible to reveal the human physiological characteristics as follows: the extremities temperature change, pulse waves and their velocity in the radial artery, breathing dynamics, blood pressure evaluated in two different regimes of brachial cuff air filling – inflation and deflation. The brachial cuff inflation also served as external interventional impact on the organism. It is found that, after the brachial artery cross-clamping, the pulse wave velocity in the radial artery is capable of doubling in comparison with that measured before compression. It is shown that the multimodal technology is a promising means in modern experimental science.
