Cutting-edge crime scene technology
The CSIR's new-generation fingerprinting sensing technology, launched in 2016, uses high-speed, largevolume optical coherence tomography (OCT).
OCT uses light to capture, in 3D, the finest of details from biological tissue.
It could be likened to ultrasound, but using light.
The OCT device will contribute to law enforcement and forensics.
Crime-scene personnel can use the OCT device to scan areas and lift fingerprints without the use of dusting and the risk of contamination.
The contactless nature of the scan means that multiple acquisitions are possible. Since OCT is nondestructive, secondary analyses can be performed and used to identify criminals.
It can also detect sweat glands and can also detect if the subject being scanned is dead or alive.
These important qualities enhance biometric security features for high-end applications such as military, national security points, and forensics.
