Automated characterisation of multi-view fringe projection system for three- dimensional measurement of additively manufactured parts (2019)
Presentation / Conference Contribution
Leach, R. K., Shaheen, A., Piano, S., Sims-Waterhouse, D., & Bointon, P. (2019, September). Automated characterisation of multi-view fringe projection system for three- dimensional measurement of additively manufactured parts. Presented at Special Interest Group Meeting: Advancing Precision in Additive Manufacturing, Ecole Centrale de Nantes, Nantes, France

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...

Modelling Fringe Projection Based on Linear Systems Theory and Geometric Transformation (2019)
Presentation / Conference Contribution
Gayton, G., Su, R., & Leach, R. (2019, September). Modelling Fringe Projection Based on Linear Systems Theory and Geometric Transformation. Presented at 14th International Symposium on Measurement Technology and Intelligent Instruments (ISMTII2019), Niigata, Japan

Fringe projection measurement techniques offer fast, non-contact measurements of the surface form of manufactured parts at relatively low cost. Recent advances in fringe projection have reduced measurement errors from effects such as multiple surface...

Three-dimensional resonating metamaterials for low-frequency vibration attenuation (2019)
Journal Article
Elmadih, W., Chronopoulos, D., Syam, W., Maskery, I., Meng, H., & Leach, R. (2019). Three-dimensional resonating metamaterials for low-frequency vibration attenuation. Scientific Reports, 9(1), Article 11503. https://doi.org/10.1038/s41598-019-47644-0

Recent advances in additive manufacturing have enabled fabrication of phononic crystals and metamaterials which exhibit spectral gaps, or stopbands, in which the propagation of elastic waves is prohibited by Bragg scattering or local resonance effect...

Automated assessment of object coverage in smart, optical form measurement (2019)
Presentation / Conference Contribution
Catalucci, S., Senin, N., Stavroulakis, P., & Leach, R. (2019, June). Automated assessment of object coverage in smart, optical form measurement. Presented at 19th International euspen Conference & Exhibition, Bilbao, Spain

As part of a project to develop a smart 3D form measurement system for quality control of complex 3D parts, we present early work in algorithmic assessment of coverage achieved on the surfaces of a part subjected to optical measurement from a single...

All-optical difference engine for in-process defect inspection for roll-to-roll printed electronics (2019)
Presentation / Conference Contribution
Feng, X., Su, R., Happonen, T., Liu, J., & Leach, R. (2018, August). All-optical difference engine for in-process defect inspection for roll-to-roll printed electronics. Presented at 10th International Symposium on Precision Engineering Measurements and Instrumentation (ISPEMI 2018), Kunming, China

© 2019 SPIE. The increasing capabilities of roll-to-roll (R2R) printing processes present challenges for quality control, requiring inprocess inspection of large substrates with high resolution at high speed. In this paper, an all-optical difference... Read More about All-optical difference engine for in-process defect inspection for roll-to-roll printed electronics.
