A portable device that could scan fingerprints in microseconds has been developed by scientists in India. The system, which works using a technique called optical coherence tomography, promises to be better than existing fingerprint detection methods since it does not require any chemical processing. Optical coherence tomography (OCT) is like an optical version of ultrasound imaging. The technique is already routinely used in medicine, but has not had a forensic application until now.
