CSIR’s Optical Coherence Tomography Fingerprint Sensor: Laser Identity Verification
What would happen if you don’t have fingerprints? Burns, ageing, solvents and a number of other conditions could remove your obvious external fingerprint. This tech allows a sub-dermal scan of the finger using a laser to obtain the print even if there is superficial damage. Whats more, it can be used for crime scenes but it doesn’t disturb the crime scene and will identify faked fingerprints.
