| description | An optical sensor module for detecting and/or measuring physiological information that can be integrated into a wearable device, such as a headset, a wristband, a ring, etc., includes a housing supporting an optical source and an optical detector. The housing overlies the optical source and optical detector and includes a first light guide comprising light transmissive material in optical communication with the optical source and a second light guide comprising light transmissive material in optical communication with the optical detector. The first and second light guides define respective first and second axial directions that are outwardly diverging. When the sensor module is in use and placed adjacent the skin of a user, light rays emanating from the optical source and directed into the skin of the user cannot overlap with light rays returning through the skin of the user. |
