Towards metrology systems on a chip using photonic integration.

This PhD project will investigate routes to the creation of optical metrology systems-on-a-chip, where photonic integration will be used to develop a miniaturised broadband interferometry system comprising light sources, detectors and other necessary sub-components, to achieve low-cost miniaturised sensors for the measurement of surface topography, layer thickness and position/displacement.

Application of advanced measurement techniques to tool mark investigation.

This project will focus on:
• Determining the characteristics of tool marks and the best practice for measurement of the topography
• Exploring casting techniques used when the tool mark cannot be transported to the lab (i.e. doorframes) and the effect
of casting on the fidelity of the replica
• Applying correlation techniques to the areal surface
• Analysing possible error rates in the investigation.

Under the Skin of Ultra-Precision Manufacturing

This studentship concerns research in advanced robotic manufacture of ultra-precision surfaces in glassy materials, required for numerous applications in science, medicine, and industry. Fine surface processing involves “rubbing” rather than cutting, is of limited predictability, and still poorly understood. The studentship is associated with a major new EPSRC-funded project to deepen that understanding, by exploring challenging multi-physics, multi-scale science at the interface between computational fluid dynamics and molecular dynamics. This will be informed by controlled experiments with extensive process-monitoring, with modelling reinforced by machine learning. The
the end-game is to use real-time process-monitoring to keep processes ‘on track’, reducing manufacturing cost, time and defect rate.
