  • Darlow, LN; Webb, L; Botha, N (OSA Publishing, 2016-05)
    Fingerprint recognition systems are prevalent in high-security applications. As a result, the act of spoofing these systems with artificial fingerprints is of increasing concern. This research presents an automatic means ...
  • Kok, S; Botha, N; Inglis, M (John Wiley & Sons, 2014-08)
    Goldmann applanation tonometry (GAT) is a method used to estimate the intraocular pressure by measuring the indentation resistance of the cornea. A popular approach to investigate the sensitivity of GAT results to material ...
  • Singh, A; Sharma, Ameeth; Roberts, T; Khutlang, R; Ramokolo, R; Marome, N; Webb, L; Botha, N; Karsten, A; Strauss, H (CSIR, 2015-10)
    This poster Celebrating the Year of Light….. from medicine to security with Optical Coherence Tomography was presented at the CSIR’s 5th Conference, 8-9 October 2015.
  • Uys, H; Akhalwaya, I; Botha, N; Burd, S; Hendriks, A; Madigoe, R; Ombinda, S; Smit, A; Kloppers, H; Steyn, J; Botha, L (2012-10)
    In this presentation the authors discuss the technological relevance of quantum mechanics, and describe how researchers use light to control the atomic and molecular world at its most fundamental level.
  • Bogaers, Alfred; Botha, N (2016-10)
    The aim of this paper is to outline a preliminary investigation into an energy optimisation model with the aim of eventually being incorporated into a real-time driver assist program. A significant portion of the South ...
  • Botha, N; Kok, S; Inglis, HM (SAAM, 2012-12)
    Corneal biomechanical properties are an important element in the study of corneal biomechanics. There are currently two techniques to obtain these properties; an inflation test and the strip extensiometry test. As the ...
  • Botha, N; Botha, L; Du Plessis, A; Schwoerer, H (CSIR, 2010-08-31)
    Femtosecond pulse shaping can be done by different kinds of pulse shapers, such as liquid crystal spatial light modulators (LC SLM), acousto optic modulators (AOM) and deformable and movable mirrors. A few applications ...
  • Botha, N; Kok, S; Inglis, HM (2012-07)
    Glaucoma is the second leading cause of irreversible blindness. The primary indicator for glaucoma is an elevated intraocular pressure, which is estimated by means of contact or non-contact tonometry. However, these ...
  • Botha, N (2012-10)
    This presentation outlines how the intraocular pressure inside the human eye can be estimated using numerical techniques. This can be used as a risk indicator in the diagnosis of glaucoma.
  • Botha, N; Botha, L; Du Plessis, A; Uys, H; Schoewer, H (2010-10)
    The design of the pulse shaping setup as well as factors taken into account in choosing a specific setup will be discussed. We investigate the generation of simple shaped pulses to test our pulse shaper setup. Difference ...
