Abstract
A device, system and method of non-invasive monitoring of physiological measurements of a subject are disclosed. The method may include: emitting light beams towards skin of the subject, with at least one light source having at least one predetermined polarization, wherein the light beams are emitted at an angle 0°≤α<90° relative to the normal to the skin surface of the subject; sensing light beams with at least one light sensor positioned at a predetermined distance from the at least one light emitting source; filtering out signals corresponding to detected light beams based on the at least one predetermined polarization of the at least one light source; and determining at least one physiological signal, based on the sensed light beams after filtering. The sensed light beams may pass through at least one of epidermis, dermis, subcutaneous tissue and blood vessel of the subject.
