摘要：
A wearable device includes a housing, at least one optical emitter supported by the housing, wherein the at least one optical emitter is configured to generate modulated light, at least one optical detector supported by the housing, and a tip removably secured to the housing. The tip includes first and second portions, wherein the first portion directs light along a first path from the at least one optical emitter to a body of a subject wearing the device, and wherein the second portion directs light from the body of the subject to the optical detector along a second path that is different from the first path. The device may also include an analog-to-digital converter, a motion sensor, and a processor. The processor executes a first filter that attenuates sunlight noise and a second filter that attenuates motion artifacts.
