Abstract:

ENGLISH ABSTRACT: Historically organisations have had the "luxury" of being able to anticipate future developments and respond to them in good time due to, firstly, the comparatively slow pace of change and, secondly, the past being a relatively good predictor of the future. The second half of the 20th Century bears witness to some of the most dramatic changes and developments experienced by mankind. Most notable of these were globalisation,de-regulation, the emergence of the information/knowledge economy and, perhaps most significant of all, the changes brought about by the Internet. The unde

Abstract:

This work details two investigations into image capture, taken from the fields of x-ray and laser research, and also details two scanning systems: a wire surface generator and a video security device. Firstly a camera system is described that can display images, digitize them and provide real time false shading. This camera is shown to have a linear intensity response and to have a maximum saturation level below the digitizing range. Some example outputs are then illustrated. The ability to irradiate CCDs with direct X-ray radiation is also investigated. A camera is developed that vertically i

Abstract:

A scanning force microscope is an instrument which can image the forces present on a sample with high resolution. These forces include magnetic, electric, and atomic forces. The scanning force microscope uses either a tunneling, capacitive or optical method of sensing the motion of a lever-tip mechanical system that reacts to the forces present on a sample. There are four optical methods used in scanning force microscopy: heterodyne, homodyne, deflection and laser feedback. In this thesis, two implementations of the laser feedback method of detecting lever motion are described: a fiber coupled

Abstract:

Galvanometer laser machining is a well-established laser machining technique in which the laser beam is positioned on a working field by means of mirrors mounted in galvanometers. Nonetheless, new applications make necessary the development of innovative techniques for increasing the performance of such systems. Aside all the advantages of this technique like given resolution, repeatability and velocity, a limited working area is an important drawback. In this thesis work, the limitations of different state-of-the-art schemes for increasing the working field of galvanometer laser machining s

Abstract:

Single-photon emission computed tomography (SPECT) is a modality widely used to detect myocardial ischemia and myocardial infarction. Objectively assessing and comparing different SPECT systems is important so that the best detectability of cardiac defects can be achieved. Whitaker, Clarkson, and Barrett's study on the scanning linear observer (SLO) shows that the SLO can be used to estimate the location and size of signals. One major advantage of the SLO is that it can be used with projection data rather than reconstruction data. Thus, this observer model assesses overall hardware performance

Structured light systems (SLS) use a projector to illuminate the surface of the scanned object, and a camera to capture the surfaces' reflection. By projecting a series of specific line-patterns, the pixel columns of the digital projector can be identified off the scanned surface. 3D points can t

Abstract:

Many applications in optical research require the use of diffraction limited point images with reduced spot sizes. The instrumentation that evaluates these small diameter images must have high resolution (sub-micron) capabilities. One method used to measure sub-micron optical point images is a scanning grating technique. However, many characteristics of this measurement technique have not been fully examined. In this paper, the sensitivity of this measurement technique to the scanning mechanism, beam characteristics, and grating tilt is evaluated.
