    Abstract: The present invention relates to a device, system and method for extracting physiological information indicative of at least one vital sign of a subject. To solve the motion robustness problem of known solutions, the device comprises a pre-treatment unit (210) configured to derive at least three detection signals from electromagnetic radiation reflected from a skin region of a subject, wherein at least two detection signals comprise wavelength-dependent reflection information in a different wavelength channel and at least two detection signals comprise reflection information in different polarization channels having different polarization directions. This provides that a channel that always has a low pulsatility, even when the SpO2 value is low. This channel mainly contains the motion-induced distortions. Adding this always low-pulsatile channel to the generally known PBV pulse extraction or the ABPV SpO2 measurement algorithm, or replacing an existing channel solves the reduced motion robustness problem of the known systems and methods.
