Abstract
A remote photoplethysmography system includes a filter (10) for application to a detection unit. The filter further includes a first filter area (11) configured to transmit light (A) at a first wavelength and a second filter area (12) configured to transmit light (D) at a second wavelength. The detection unit (22) detects radiation received from the first filter area and from the second filter area of the filter. An analysis unit (6) determines the vital sign information of the subject from the detected radiation from the first filter area and from the second filter area.
