Development of camera-based systems for micro-coordinate metrology – Mr Danny Sims-Waterhouse
Manufacturing components with micro or nano-scale features is quickly becoming a mainstream application of engineering. Currently contact based measurement systems are mainly used, but lack the speed required for manufacturing on any reasonable scale. Therefore, we must look to optical techniques to provide the speed and accuracy needed for the next generation of manufacturing metrology. The project will centre on developing new camera-based 3D measurement systems for high-precision coordinate metrology. Special focus will be placed on the ability to measure features with high slope angles and high aspect ratios, often outside the aperture range of the optics. Techniques to be considered include photogrammetry and fringe projection, including hybrid designs. A wide variety of cameras and lenses properties will also be considered, such as the lens type shown in Figure 1. A number of case study components will be measured using the techniques
Danny is undertaking his PhD with the Manufacturing Metrology Team at the University of Nottingham led by Prof Richard Leach.
