Display motion error reduction through novel binary dithering schemes
This project is an investigation into display motion performance. Experiments using a prototype and computer modelling have demonstrated that fast switching binary displays can potentially display colour images at over 500Hz using novel techniques, greatly benefiting applications such as virtual reality by reducing latency and blurring.

Development and optimisation of an optofluidic nano tweezers system for trapping nanometre crystals for synchrotron x-ray diffraction experiments
This project investigates optofluidic technology and evanescent field optical tweezing as more efficient and biologically compatible sample loading solution for micro and nano protein crystals, in synchrotron and free electron lasers (X-FELS) x-ray crystallography beamlines. The project is both sponsored and in collaboration with the Diamond light source national synchrotron.

Anode materials for vacuum electronics devices
The project focuses on eliminating the anode’s contribution to outgassing and plasma formation caused by the near surface ionization of the outgassed neutral atoms by the desorbed electrons, thus increasing the lowest achievable pressure in vacuum electronics devices improving their efficiency.

Design, fabrication and characterisation of hierarchical branching vascular networks
The main challenge in the research of artificially engineered tissue is the vascularization of tissue. The focus of the project is to develop, with an algorithm, realistic vascular networks in a given three-dimensional space, and the experimental fabrication and study of flow within the networks.

Development of non-contact methods for measuring the outside geometry of AM parts
Additive manufacturing is rapidly growing with more and more industries incorporating it in their manufacturing processes. However, before it can be widely adopted in the manufacturing industry, purpose built metrology systems must be designed to ensure tight tolerances and traceability are provided. The aim will be to develop an optical metrology system for measuring the complex outside form of AM parts.

Development of a precision fibre optic CO2 sensor for the potential use in healthcare assessment
This PhD project is focussed on fabricating a carbon dioxide sensor for healthcare monitoring. The use of optical fibre modulations and CO2 sensitive coatings will allow precise measurements to be determined.

Real-time metrology of micro-targets for high power laser systems operating at high repetition rates
Microtargets irradiated by high power lasers (HPL) enable experimental study of a wide range of objects and materials under extreme conditions, for example, ion production for potential future oncology techniques, laboratory astrophysics and ‘inertial fusion energy’.

Development of camera-based systems for micro-coordinate metrology
New camera-based 3D measurement systems for high-precision coordinate metrology will be developed. Techniques to be considered include photogrammetry and fringe projection, including hybrid designs. A number of case study components will be measured using the techniques to demonstrate their performance with different geometries, materials and surface textures.

Spatial light modulators and its application in computer generated holograms
Holographic displays have attracted more and more attention in these days, and there is a huge market for relevant products. The research is focused on Optically Addressed Spatial Light Modulators (OASLMs), in comparison to Electrically Addressed Spatial Light Modulators (EASLMs).

Ultrafast machining of high temperature superconductor nanostructures for novel mesoscale physics
High temperature superconductors (HTS) are novel materials that exhibit zero electrical resistance and exclusion of magnetic fields at temperatures over 77 K. The main aim of this project is to enhance the critical current density (Jc) of thin-film HTS bridges by creating edge-barrier pinning. Assuming a perfect edge, edge-barrier pinning effects bridges as large as 200 μm. This limit becomes smaller as edge quality degrades. Unlike photolithography, laser machining is a chemical free, flexible process; the use of an ultrafast laser gives minimal edge damage.
