Abstract
An ear worn device includes an optical source, an optical detector, and a housing supporting the optical source and optical detector. The housing is configured to be positioned within an ear of a subject and includes a first light guide in optical communication with the optical source and a second light guide 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 ear, and a distal end of the second light guide is configured to collect light from the ear and deliver collected light to the optical detector. The first and second light guides define respective first and second axial directions that are outwardly diverging such that light rays directed into the ear via the first light guide cannot overlap with light rays collected by the second light guide.
