Comparison of two noise reduction methods in coherence scanning interferometry for surface measurement (2019)
Conference Proceeding
Gomez, C., Su, R., Lawes, S., & Leach, R. (2019). Comparison of two noise reduction methods in coherence scanning interferometry for surface measurement

Coherence scanning interferometry (CSI) can measure relatively flat surfaces with sub-nanometre precision, but the measurement noise may increase significantly if the intensity of the interferometric signal reduces when measuring non-flat surfaces or...

Optimisation of surface topography characterisation for metal additive manufacturing using coherence scanning interferometry (2017)
Conference Proceeding
Gómez, C. A., Su, R., Thompson, A., DiSciacca, J., Lawes, S., & Leach, R. K. (2017). Optimisation of surface topography characterisation for metal additive manufacturing using coherence scanning interferometry.

The surface topography of metal additive manufactured (AM) parts can be challenging to measure due to the presence of complex features, such as high slopes, step like recesses and protuberances, and local variations in reflectance. Recent innovations... Read More about Optimisation of surface topography characterisation for metal additive manufacturing using coherence scanning interferometry.

Results of an industrial survey on the use of surface texture parameters (2017)
Conference Proceeding
Todhunter, L. D., Leach, R., & Lawes, S. (2017). Results of an industrial survey on the use of surface texture parameters.

In 1999, CIRP conducted an industrial survey of the use of surface texture parameters [1]. In the seventeen years since, much has changed, with the most important advancement being the introduction of areal surface texture parameters as described in...

Measurement of internal surfaces of additively manufactured parts by X-ray computed tomography (2017)
Conference Proceeding
Thompson, A., Körner, L., Senin, N., Lawes, S., Maskery, I., & Leach, R. K. (2017). Measurement of internal surfaces of additively manufactured parts by X-ray computed tomography.

Recent advances in X-ray computed tomography (XCT) have allowed for measurement resolutions approaching the point where XCT can be used for measuring surface topography. These advances make XCT appealing for measuring hard-to-reach or internal surfac... Read More about Measurement of internal surfaces of additively manufactured parts by X-ray computed tomography.
