This project aims to achieve safer, faster, and cheaper 3D X-ray imaging through a technique known as ghost imaging. X-ray imaging provides valuable information about internal structures, however, X-rays are carcinogenic and exposure (or dose) should be limited. Ghost imaging is an unconventional technique developed with visible light that has many potential benefits over conventional imaging. This research group are world leaders in ghost imaging and expect to develop software and hardware techniques to realise its potential and extend it to ghost tomography. The focus of this project is on reducing cancer risk in medical imaging, and allowing real-time quality control for 3D printing in safety-critical industries such as aerospace.Read moreRead less
Unlocking the potential of quantitative x-ray micro-tomography. This project aims to build on two new ideas in data acquisition and 3D image reconstruction to bring 3D X-ray microscopy or computed tomography (CT) into advanced research use as well as common industrial applications. In the past 10 years, CT has improved our understanding in areas ranging from the evolution of life and osteoporosis to composite material failure and oil recovery. However, the full potential of CT remains unrealised ....Unlocking the potential of quantitative x-ray micro-tomography. This project aims to build on two new ideas in data acquisition and 3D image reconstruction to bring 3D X-ray microscopy or computed tomography (CT) into advanced research use as well as common industrial applications. In the past 10 years, CT has improved our understanding in areas ranging from the evolution of life and osteoporosis to composite material failure and oil recovery. However, the full potential of CT remains unrealised because crucial features in structure and composition are overlooked by simplistic algorithms. Users cannot directly capture quantities of interest such as key compositional variation or defects, and workflows are poorly adapted for large-scale use in industrial fabrication or phenomics. This project aims to address these shortcomings using advanced mathematics and algorithms.Read moreRead less

This project aims to test Alternative Listening Devices/Personal Sound Amplification Devices (PSAPs), multi-input audio devices fast replacing hearing aids due to their affordability and easy accessibility. With more consumers choosing PSAPs, proper testing is needed to assess the devices’ safety and benefit in real-life acoustic situations. This project will test PSAPs in laboratory setups that use spatial audio processing techniques to mimic realistic acoustic environments, and develop theoretical frameworks to overcome existing limitations to accurate spatial sound reproduction. This research is expected to provide innovative solutions to safeguard Australia's future hearing health.Read moreRead less

Precision laser levitation for quantum metrology and gravitational sensing. Precision laser levitation for quantum metrology and gravitational sensing: This fellowship project aims to levitate macroscopic objects using only laser beams, to provide a new tool to test physics theories. Strong laser beams can exert sufficient force to counteract gravity and make an object levitate.

Precision laser levitation for quantum metrology and gravitational sensing: This fellowship project aims to levitate macroscopic objects using only laser beams, to provide a new tool to test physics theories. Strong laser beams can exert sufficient force to counteract gravity and make an object levitate. In contrast to other forms of levitation, laser levitation is scatter-free and can preserve system coherence. It has superior optical and mechanical quality factors and complete information of the system dynamics is retained. This allows laser levitation to be turned into a highly controllable and ultra-sensitive device capable of detecting minute environmental changes. This research aims to probe the relationship between quantum and gravitational physics and develop laser levitation into a precision instrument for the sensing of gravity. Laser levitation has the potential to be developed into technology for mineral exploration and environmental sensing.Read moreRead less
Coherent Laser Levitation for Precision Sensing and Enabling Science. When light collides with matter, it may exert a force called radiation pressure. This project aims to use radiation pressure to levitate a small mirror. Using a tripod of laser beams, it is possible to levitate and trap the mirror in a stable position. Radiation pressure has been used before to levitate, but previous work has always involved scattering light from the levitating object. This project proposes the use of a high q ....Coherent Laser Levitation for Precision Sensing and Enabling Science. When light collides with matter, it may exert a force called radiation pressure. This project aims to use radiation pressure to levitate a small mirror. Using a tripod of laser beams, it is possible to levitate and trap the mirror in a stable position. Radiation pressure has been used before to levitate, but previous work has always involved scattering light from the levitating object. This project proposes the use of a high quality mirror, allowing the collection of the reflected light and the accurate measurement and control of the position of the mirror as it floats on the laser beams. Using the unique properties of the floating mirror, it will be possible to search for signatures of quantum gravity and develop tools for ultra-precision metrology.Read moreRead less
