New Touchless 3D Fingerprinting System


Lines of light are projected on a finger to illuminate the print. The light is warped by the ridges and valleys of the fingertip, allowing researchers to generate a 3-D fingerprint.

A new non-contact, 3-D fingerprinting system could make spotting the bad guys faster and easier, whether it’s at the border or the police precinct. By projecting patterns of light onto a finger and analyzing the image, researchers from the University of Kentucky are able to create a more accurate print than those made with ink or sensor plates. The researchers say the system is more efficient than traditional fingerprinting and significantly reduces the number of incorrect matches.
