FIELD: medicine.
SUBSTANCE: group of inventions relates to medicine. Method of remote monitoring for extracting physiological information from detected electromagnetic radiation, emitted or reflected by a subject, is carried out using a remote monitoring device. Electromagnetic radiation is collected by means of a sensor means at a distance. Sensor means comprises a predetermined amplitude-frequency characteristic, adapted for at least two predetermined spectral distributions. Data stream from the detected electromagnetic radiation is received via an interface. Continuous or discrete characteristic signal of the data stream includes physiological information, indicative of a vital parameter. Indicative component of the characteristic signal characterises the detected spectral region, indicative of the vital parameter, obtained on the basis of cardiovascular activity. Data stream at least sectionally comprises an auxiliary signal component detected along with the indicative component. Auxiliary component is representative of a distinct spectral portion. Characteristic signal discrepancy between the indicative and auxiliary components is detected using a comparator, the signal discrepancy being related to a physiological state of the subject. Signal discrepancy is the time difference of signals, characterising the actual position of the body of the subject. Signal calibration parameter is determined using calibration means under consideration of the detected signal discrepancy.
EFFECT: high accuracy of the measured signal.
