Choice of spatial resolution measurement methods to implement: considerations under a “New Laboratory”-scenario for imaging optical testing and research

Author: Theron, Bertus ; El-Desouki, M ; Aljekhedab, FMR ; Alayed, MSI ; Alsawad, MSD Date: Apr 2013 A key imaging quality metric for an optical system (e.g. a camera or surveillance device) is its resolution. Methods to measure this, range from visual observation methods on resolution target charts, through more rigorous characterization, ... Read more
Ensuring validity of radiometric temperature measurements obtained in the field using infrared imagers

Author: Mudau, AE ; Willers, Cornelius J ; Hlakola, M ; Calitz, H ; Theron, Bertus Date: Nov 2010 When a military aircraft becomes the target of an approaching infrared seeker missile, it relies on infrared counter-measures to serve as decoys and to confuse the missile. The Optronic Sensor Systems (OSS) group at CSIR-DPSS is involved in ... Read more
Fibre optic power meter calibration uncertainties

Author: Nel, M ; Theron, Bertus Date: Jun 2010 This article discusses the determination of uncertainty contributions when performing a power responsivity calibration for a fibre optic power meter. Read more
Infrared measurements in defence application

Author: Mudau, AE ; Willers, Cornelius J ; Hlakola, MJ ; Le Roux, FPJ ; Theron, Bertus ; Calitz, JJ ; Du Plooy, MJU Date: Mar 2011 The optronic sensor systems (OSS) competency area (CA) at the CSIR unit for defence, peace, safety and security (DPSS) performs directed research and development and builds technology demonstrators in the fields of optical design, modelling, ...

Laboratory testing & measurement on optical imaging systems

Author: Theron, Bertus Date: Apr 2013 The purpose of the workshop was for participants to interactively discuss (with regard to optical imaging or optical imaging systems): Local end-user needs; What those needs imply for associated new & existing laboratory testing & measurement ... Read more
On a popular myth: “Scientific research cannot be subject to quality management”. Think again! Who says it cannot be?

Author: Theron, Bertus Date: Jul 2012 In many scientific research environments the popular belief seems to be that scientific research cannot be subject to so-called “quality” management, at least not down to the research operational level. Examples of popular arguments behind ... Read more
Quantifying uncertainty contributions for fibre optic power meter calibrations

Author: Nel, M ; Theron, Bertus Date: Sep 2009 A fibre optic power meter calibration has several uncertainty contributors associated with it. In order to assign a realistic uncertainty to the calibration result it is necessary to realistically estimate the magnitude of each uncertainty ... Read more
