Damage invariant and high security acquisition of the internal fingerprint using optical coherence tomography

Author: Darlow, Luke N ; Singh, Ann ; Moolla, Yaseen ; Ramokolo, Lesiba R ; Van Wyk, R ; Botha, Natasha ; Webb-Ray, L Date: Nov 2016 Fingerprints are widely used for biometric authentication, identification, and access control. However, most current acquisition devices obtain fingerprints from the surface of the skin and are thus inherently restricted by the surface 2D ... Read more
Detecting defects during powder deposition in additive manufacturing

Author: Hendriks, Adriaan J ; Ramokolo, Lesiba R ; Ngobeni, Christopher M ; Moroko, Matome C ; Naidoo, Darryl Date: Nov 2018 Additive manufacturing applications, in areas such as aerospace and medicine, are limited due to the lack of process stability and quality management. In particular, geometrical inaccuracies and the presence of mechanical defects hinder ... Read more
A high speed OCT system developed at the CSIR National Laser Centre (paper)

Author: Sharma, Ameeth ; Singh, Ann ; Roberts, Ted ; Ramokolo, Lesiba R ; Strauss, Hencharl J Date: Jul 2016 Light-based techniques continue to gain momentum in different spheres of diagnostic and therapeutic applications due to their non-invasive, non-contact properties. One such technique is Optical Coherence tomography (OCT). Since first being ... Read more
