光学生命体征传感器
摘要：
一种被配置为测量或确定用户的生命体征的光学生命体征传感器，包括光源(110)，所述光源被配置为生成具有入射角度(α)的角度范围的光束(111)。所述光束(111)被指引朝向所述用户的皮肤(1000)。光探测器被提供并且被配置为探测指示来自所述光源(110)的光束(111)在所述用户的皮肤(1000)中或来自所述用户的皮肤(1000)的反射的光。所述光源(110)和所述光探测器(120)彼此邻近地布置并且被布置在所述用户的皮肤(1000)的同一侧。光整形单元被配置为通过将入射角度(α)的角度范围限制到小于20°而在光束(111)进入皮肤(1000)之前对所述光源(110)的光束进行整形。
摘要（英）：

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 (Alpha). 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 (Alpha) to less than 20 DEG C.
