摘要:
An optical vital signs sensor configured to measure or determine vital signs of a user comprises alight source (110) configured to generate a light beam (111) having an angular range of angles of incidence (a). The light beam (111) is directed towards the skin (1000) of the user. A photo detector is provided and is configured to detect light which is indicative of a reflection of the light beam (111) from the light source (110) in or from the skin (1000) of the user. The light source (110) and the photo detector (120) are arranged adjacent to each other and on the same side of the skin (1000) of the user. Alight shaping unit is configured to shape the light beam of the light source (110) before the light beam (111) enters the skin (1000) by limiting the angular range of angle of incidence (a) to less than20°.
