Multi-view fringe projection system for surface topography measurement during metal powder bed fusion (2020)
Journal Article
Dickins, A., Widjanarko, T., Sims-Waterhouse, D., Thompson, A., Lawes, S., Senin, N., & Leach, R. (2020). Multi-view fringe projection system for surface topography measurement during metal powder bed fusion. Journal of the Optical Society of America A, 37(9), B93-B105. https://doi.org/10.1364/JOSAA.396186

Metal powder bed fusion (PBF) methods need in-process measurement methods to increase user confidence and encourage further adoption in high-value manufacturing sectors. In this paper, a novel measurement method for PBF systems is proposed that uses...

Review of the influence of noise in X-ray computed tomography measurement uncertainty (2020)
Journal Article
Sánchez, Á. R., Thompson, A., Körner, L., Brierley, N., & Leach, R. (2020). Review of the influence of noise in X-ray computed tomography measurement uncertainty. Precision Engineering, https://doi.org/10.1016/j.precisioneng.2020.08.004

Different aspects of noise in X-ray computed tomography (XCT) for industrial purposes are examined. An overview of the most common noise metrics is given, together with a description of XCT noise influence quantities. We address the current state of...

Ceria-coated replicated aluminium sponges as catalysts for the CO-water gas shift process (2020)
Journal Article
Palma, V., Goodall, R., Thompson, A., Ruocco, C., Renda, S., Leach, R., & Martino, M. (2021). Ceria-coated replicated aluminium sponges as catalysts for the CO-water gas shift process. International Journal of Hydrogen Energy, 46(22), 12158-12168. https://doi.org/10.1016/j.ijhydene.2020.04.065

A study on the use of chemical conversion coating as a preparative technique for foam-based structured catalysts, in the water gas shift reaction, is presented. The results showed a significant correlation between the textural properties of the struc...

Polymer powder bed fusion surface texture measurement (2020)
Journal Article
de Pastre, M., Thompson, A., Quinsat, Y., Albajez, J. A., Senin, N., & Leach, R. K. (2020). Polymer powder bed fusion surface texture measurement. Measurement Science and Technology, 31(5), https://doi.org/10.1088/1361-6501/ab63b1

Polymer laser powder bed fusion (LPBF) surfaces can be challenging to measure. These surfaces comprise complex features including undercuts, deep recesses, step-like transitions, a large range of measurement scales and unfavourable optically material...
