CSIR National Laser Centre develops a high speed OCT system

Author: Sharma, Ameeth ; Singh, Ann ; Roberts, Ted ; Ramokolo, Lesiba R ; Van der Westhuizen, Corrie Date: Nov 2016 The optical coherence technique (OCT) technique, which was demonstrated by Fercher and Huang in the early 90s, has made significant strides in bio-medical diagnostic applications in the fields of dermatology, dentistry and ophthalmology. Other ... Read more
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
Fingerprint matching with optical coherence tomography

Author: Moolla, Yaseen ; Singh, A ; Saith, E ; Akhoury, S Date: Dec 2015 Fingerprint recognition is an important security technique with a steadily growing usage for the identification and verification of individuals. However, current fingerprint acquisition systems have certain disadvantages, which include the ... Read more
High resolution feature extraction from optical coherence tomography acquired internal fingerprint

Author: Khutlang, Rethabile ; Khanyile, Nontokozo P ; Makinana, Sisanda ; Nelwamondo, Fulufhelo V Date: May 2016 Biometric fingerprint scanners scan the external skin features onto a 2D image. The performance of the automatic fingerprint identification system suffers if the finger skin is wet, worn out, fake fingerprint is used et cetera. Swept source ... 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
Internal fingerprint zone detection in optical coherence tomography fingertip scans

Author: Darlow, LN ; Connan, J ; Akhoury, SS Date: Apr 2015 Optical coherence tomography (OCT) is a high-resolution imaging technology capable of capturing a three-dimensional (3-D) representation of fingertip skin. The papillary junction—a junction layer of skin containing the same topographical ... Read more
Latent fingerprint wavelet transform image enhancement technique for optical coherence tomography

Author: Makinana, S ; Khanyile, PN ; Khutlang, Rethabile Date: Sep 2016 In crime investigation, fingerprint identification plays a major role in identifying culprits. However, traditional procedure of acquiring latent fingerprint tends to be destructive and leads to a limitation of not being able to do further ... Read more
Novelty detection-based internal fingerprint segmentation in optical coherence tomography images

Author: Khutlang, Rethabile ; Machaka, Pheeha ; Singh, Ann ; Nelwamondo, Fulufhelo V Date: Aug 2017 Biometric fingerprint scanners scan the external skin's features onto a 2-D image. The performance of the automatic fingerprint identification system suffers first and foremost if the finger skin is wet, worn out or a fake fingerprint is used. ... Read more
Novelty detection-based internal fingerprint segmentation in optical coherence tomography images

Author: Khutlang, Rethabile ; Nelwamondo, Fulufhelo V Date: Dec 2014 Biometric fingerprint scanners scan the external skin features onto a 2-D image. The performance of the automatic fingerprint identification system suffers if the finger skin is wet, worn out, fake fingerprint is used et cetera. In this paper, ... Read more
Optical coherence tomography as a research tool for biomaterials

Author: Karsten, AE ; Singh, A ; Ndhundhuma, I Date: Jan 2010 In this study a commercial FD-OCT (Model OCM1300SS) by Thorlabs Inc., USA was used. This system has the following performance specifications: 1300nm centre operating wavelength, a 110nm 3dB spectral bandwidth, transverse spatial air resolution ... Read more
Optical coherence tomography latent fingerprint image denoising

Author: Mgaga, Sboniso S ; Tapamo, JR Date: Dec 2020 Latent fingerprints are fingerprint impressions left on the surfaces a finger comes into contact with. They are found in almost every crime scene. Conventionally, latent fingerprints have been obtained using chemicals or physical methods, ... Read more
Optical coherence tomography, In vivo human hand explorer, optical coherence microscope

Author: Jonathan, E ; Dam, JS Date: Jul 2008 The hand palm is an important human body part primarily for physical manipulation of the environment. For example, palmar hyperhidriotics report a low quality of life due to excessive palmar sweating disrupting normal palm use. As a body part ... Read more
Performance analysis of a hybrid fingerprint extracted from optical coherence tomography fingertip scans

Author: Darlow, Luke N ; Connan, J ; Singh, Ann Date: Jun 2016 The Hybrid fingerprint is a local-quality-specific blend of the surface and internal fingerprints, extracted from optical coherence tomography scans. Owing to its origin, and the manner in which it is obtained, the Hybrid fingerprint is a ... Read more
Segmentation of forensic latent fingerprint images lifted contact-less from planar surfaces with optical cohererence tomography

Author: Khutlang, Rethabile ; Nelwamondo, Fulufhelo V ; Singh, A Date: Jul 2015 Lifting latent fingerprints through means that do not make contact with the surface where the fingerprint is imprinted, is advantageous in many ways. Some of these advantages include: being able to lift the print multiple times; there is no ... Read more
Study on internal to surface fingerprint correlation using optical coherence tomography and internal fingerprint extraction

Author: Darlow, LN ; Connan, J Date: Nov 2015 Surface fingerprint scanners are limited to a two-dimensional representation of the fingerprint topography, and thus, are vulnerable to fingerprint damage, distortion, and counterfeiting. Optical coherence tomography (OCT) scanners are able ... Read more
