Abstract: A method for measuring blood constituents is provided. The method includes radiating an area of a subject's body, containing blood constituents and dynamic and static tissue components, with at least two light beams, detecting at least one backscattered light feedback from blood constituents and dynamic and static tissue components, the feedback representing at least one interferometric signal from each of the at least two light sources, filtering the at least one interferometric signals in accordance with a frequency band which contains frequencies of interferometric oscillations, defining dynamics of blood constituents, performing analog-to-digital (AD) conversion of the filtered signals at a frequency corresponding to the frequency band, to form discrete filtered signals, obtaining from the discrete filtered signals, a set of spectral-time features of signals, and obtaining concentration of the blood constituents based on functional relationships of the obtained set of spectral-time features of signals and concentrations of the blood constituents.

Abstract: The disclosure relates to multifunctional sensors for mobile applications, namely to a miniature optical sensor for remote micro- and macro-object detection and characterization. The disclosure makes it possible to reduce the size of the sensor, this provides for surface mount of the sensor in any microcircuit of a mobile device. The sensor is multifunctional, low-power, vibration-resistant. The sensor comprises at least one pair consisting of a radiation source and a corresponding radiation receiver, an optical circuit including a collimating element, a first optical element, a second optical element. The first optical element and the second optical element are interconnected by a common surface, the common surface being a semitransparent surface. The sensor may be used simultaneously as a microphone, a dust sensor, a lidar, and a photoplethysmogram (PPG) sensor.
