Verification of a rigorous 2D model of rough surface scattering (2018)
Conference Proceeding
Thomas, M., Leach, R., Nikolaev, N., Widjanarko, T., Senin, N., Aryan, H., & Coupland, J. (2018). Verification of a rigorous 2D model of rough surface scattering.

A rigorous two-dimensional (2D) model of electromagnetic surface scatter has been developed, based on a boundary element method (BEM) established by Simonsen [1]. Simulated far-field scatter is compared to that measured from a laser scatterometer for... Read More about Verification of a rigorous 2D model of rough surface scattering.

Development of mathematical reference standards for the validation of surface texture parameter calculation software (2018)
Conference Proceeding
Todhunter, L., Leach, R., Lawes, S., Blateyron, F., & Harris, P. (2018). Development of mathematical reference standards for the validation of surface texture parameter calculation software. In n/a

A framework for the validation of surface texture parameter calculation software is proposed. The framework utilises mathematically defined surfaces and mathematically calculated surface texture parameter values to produce a reference against which t...

Curvature-based segmentation of powder bed point clouds for in-process monitoring (2018)
Conference Proceeding
Chung Chee Law, A., Southon, N., Senin, N., Stavroulakis, P., Leach, R., Goodridge, R., & Kong, Z. (2018). Curvature-based segmentation of powder bed point clouds for in-process monitoring. In 29th Annual International Solid Freeform Fabrication Symposium - an Additive Manufacturing Conference 2018

This paper presents a curvature-based analysis of point clouds collected in-process with fringe projection in a polymer powder bed fusion process. The three-dimensional point clouds were obtained from outside of the build chamber with a fringe projec...

A programmable software framework for the generation of simulated surface topography (2018)
Conference Proceeding
Todhunter, L. D., Senin, N., Leach, R., Lawes, S., Blateyron, F., & Harris, P. (2018). A programmable software framework for the generation of simulated surface topography.

A flexible and programmable software framework has been developed that enables the creation of simulated, areal surface topography datasets. The framework allows the creation of surfaces through a layered approach where deterministic topographic stru...

The effects of vibration on fringe projection systems (2018)
Conference Proceeding
Bointon, P., Todhunter, L., Stavroulakis, P., Clare, A., & Leach, R. (2018). The effects of vibration on fringe projection systems.

Mechanical vibration noise is a significant source of error in precision measuring instruments. Errors due to vibration can be detected in measurement signals, and so methods to control mechanical vibration must be considered throughout the design pr...

Lateral error compensation for focus variation microscopy (2018)
Conference Proceeding
Pérez, P., Syam, W. P., Albajez, J. A., Santolaria, J., & Leach, R. (2018). Lateral error compensation for focus variation microscopy.

Focus variation microscopy measures both the areal form and areal surface texture of components. Improvements to the accuracy and precision of focus variation microscopes usually requires measurements with multiple image-fields to compensate lateral...
