The word ‘fingerprinting’ straightaway reminds us of a stronger security check. This authentication technique has been helping law enforcement officials identify potential criminals for decades. And, its application has gained wider usage over the years now - in the form of biometrics — with government agencies, and corporations making a move toward using it for physical security.
And, thus the need for more and more powerful and sensitive fingerprint detection methods is increasing. And, it is recently, scientists in India have developed a portable detection device capable of scanning fingerprints in just microseconds! It uses the optical coherence tomography (OCT) technique for detection.
The technique is the ultrasound imaging’s optical version, which although is no new in the field of medicine, but is being used for the first time in forensic applications. Interestingly, the technique will provide a transparent 3D structural picture of a fingertip. And, hence, unlike the prevailing devices, it does not require any chemical processing.
The new technology, hence, promises a better fingerprint detection device compared to the ones already used these days.
