Detector Optode

Definition: Detector (or detection) optode is a common term which often identifies a part of an fNIRS system that is in contact with the surface of the tissue being measured. A detector optode either directly contains the photodetector (see definition of “detector”) or can hold the distal end of the detector fibers, and may also include a light guide, a lens, an optical filter and a housing.
