Automated characterisation of multi-view fringe projection system for three- dimensional measurement of additively manufactured parts (2019)
Conference Proceeding
Leach, R. K., Shaheen, A., Piano, S., Sims-Waterhouse, D., & Bointon, P. (2019). Automated characterisation of multi-view fringe projection system for three- dimensional measurement of additively manufactured parts

Digital fringe projection is a non-contact method that is widely used for the dimensional characterisation of complex manufactured parts. However, single camera-projector fringe projection systems struggle to acquire the full three-dimensional point...

Towards superresolution surface metrology: quantum estimation of angular and axial separations (2019)
Journal Article
Napoli, C., Piano, S., Leach, R., Adesso, G., & Tufarelli, T. (2019). Towards superresolution surface metrology: quantum estimation of angular and axial separations. Physical Review Letters, 122(14), doi:10.1103/physrevlett.122.140505

We investigate the localization of two incoherent point sources with arbitrary angular and axial separations in the paraxial approximation. By using quantum metrology techniques, we show that a simultaneous estimation of the two separations is achiev...

Manufacturing-error-based maintenance for high-precision machine tools (2017)
Journal Article
Shi, S., Lin, J., Xu, X., Feng, X., & Piano, S. (2018). Manufacturing-error-based maintenance for high-precision machine tools. International Journal of Advanced Manufacturing Technology, 95(1-4), doi:10.1007/s00170-017-1070-y

Nowadays, the condition-based maintenance (CBM), in which repairs are triggered by the heuristic symptoms of the component faults, is finding increasing applications in the industrial fields. However, for the high-precision machine tools, the convent... Read More about Manufacturing-error-based maintenance for high-precision machine tools.

Flexible decoupled camera and projector fringe projection system using inertial sensors (2017)
Journal Article
Stavroulakis, P., Sims-Waterhouse, D., Piano, S., & Leach, R. K. (in press). Flexible decoupled camera and projector fringe projection system using inertial sensors. Optical Engineering, 56(10), https://doi.org/10.1117/1.OE.56.10.104106

Measurement of objects with complex geometry and many self occlusions is increasingly important in many fields, including additive manufacturing. In a fringe projection system, the camera and the projector cannot move independently with respect to ea...

By using sub-millimetre laser speckle pattern projection we show that photogrammetry systems are able to measure smooth three-dimensional objects with surface height deviations less than 1 μm. The projection of laser speckle patterns allows correspon... Read More about Verification of micro-scale photogrammetry for smooth three-dimensional object measurement.
