High Density Source-detector Array

Definition: Arrangement of sources and detectors in an interlaced lattice with the first nearest neighbor distance of up to 15 mm in adults for most implementations. It would be different in an infant head. The term “high density” allows it to be differentiated from the “traditional” sparse optode placement with several cm (~3) between optodes.
