Definition Edit

Nailbed identification technology is based on the distinct longitudinal, tongue-in-groove spatial arrangement of the epidermal structure directly beneath the fingernail. This structure is mimicked in the ridges on the outer surface of the nail.

Overview Edit

When an interferometer is used to detect phase changes in back-scattered light shone on the fingernail, the distinct dimensions of the nailbed can be reconstructed and a one-dimensional map can be generated.
