摘要：
A monitoring device includes a band capable of at least partially encircling a portion of a body of a subject. An optical source and an optical detector are supported by the band. A first light guide is in optical communication with the optical source and a second light guide is in optical communication with the optical detector. A distal end of the first light guide is configured to deliver light from the optical source into the body, and a distal end of the second light guide is configured to collect light from the body and deliver collected light to the optical detector. The first and second light guides define respective first and second axial directions that diverge outwardly from the band such that light rays directed into the body via the first light guide cannot overlap with light rays collected by the second light guide.
