Targeted rework of powder bed fusion additive manufacturing (2018)
Presentation / Conference Contribution
Dryburgh, P., Patel, R., Catchpole-Smith, S., Hirsch, M., Parry, L., Smith, R. J., …Clare, A. T. (2018). Targeted rework of powder bed fusion additive manufacturing. In Proceedings of LPM2018 - the 19th International Symposium on Laser Precision Microfabrication (#18/030)

There is a clear industrial pull to fabricate high value components using premium high temperature aerospace materials by additive manufacturing. Inconveniently, the same materials’ properties which allow them to perform well in service render them... Read More about Targeted rework of powder bed fusion additive manufacturing.

Widefield ultrastable heterodyne interferometry using a custom CMOS modulated light camera (2011)
Presentation / Conference Contribution
Patel, R., Clark, M., & Achamfuo-Yeboah, S. (2011). Widefield ultrastable heterodyne interferometry using a custom CMOS modulated light camera.

A method of detecting optical heterodyne interference fringes using a custom CMOS modulated light camera array has been developed. Widefield phase images are generated using quadrature demodulation and are kept stable using a feedback system.

Spatially Resolved Acoustic Spectroscopy Towards Online Inspection of Additive Manufacturing
Presentation / Conference Contribution
Milesh Pieris, D., Patel, R., Dryburgh, P., Hirsch, M., Li, W., Sharples, S. D., Smith, R. J., Clare, A. T., & Clark, M. (2018, September). Spatially Resolved Acoustic Spectroscopy Towards Online Inspection of Additive Manufacturing. Presented at NDT 2018 - 57th Annual Conference of the British Institute of Non-Destructive Testing, Nottingham, UK

High-integrity engineering applications such as aerospace will not permit the incorporation of components containing any structural defects. The current generation of additive manufacturing platforms yield components with relatively high levels of...

Spatially resolved acoustic spectroscopy (SRAS) microstructural imaging
Presentation / Conference Contribution
Clark, M., Clare, A., Dryburgh, P., Li, W., Patel, R., Pieris, D., Sharples, S., & Smith, R. (2019, May). Spatially resolved acoustic spectroscopy (SRAS) microstructural imaging. Presented at 45th Annual Review of Progress in Quanitative Nondestructive Evaluation, Vermont, USA

© 2019 Author(s). Spatially resolved acoustic spectroscopy (SRAS) is an acoustic microscopy technique that can image the microstructure and measure the crystallographic orientation of grains or crystals in the material. It works by measuring the velo... Read More about Spatially resolved acoustic spectroscopy (SRAS) microstructural imaging.
