We have recently made significant advances in development of all-solid-state intracavity Raman lasers generating multiwatt average powers in the near infrared and (by frequency doubling) visible spectrum, with important applications in biomedicine and remote sensing. A new generation of Raman crystals, especially tungstates, offer superior optical, mechanical and thermal properties, promising high Raman gains and choice of Stokes frequency shift. The project will investigate a range of key issues for these materials including control of the Stokes wavelength, associated polarisation control, and pump-resonator configurations giving maximum Raman laser power and efficiency. The project will lead to state-of-the-art source technology with outstanding prospects for commercialisation and practical application.Read moreRead less

The recent development of the world's first prototype combined MR-PET scanner for human use has prompted immense interest. MR-PET is likely to revolutionize clinical diagnosis and basic research, by providing exquisite structural images co-registered with simultaneous functional PET images. We will exploit the as yet unexplored potential for motion information derived from the MR system to be used to correct the simultaneously acquired PET data for patient motion. This research is an excellent opportunity for Australian researchers to make important contributions to an emerging technology with high economic potential, and will strengthen Australia's international position in engineering and biomedical systems development.Read moreRead less

The 6dF Galaxy Survey - Mass and Motions in the Nearby Universe. The 6dF Galaxy Survey will yield by far the largest and most detailed map of the positions and motions of galaxies in the nearby universe. The goal of the survey is to determine the distributions of both the galaxies and the dark matter in order to measure fundamental cosmological parameters and constrain models of galaxy formation. The survey will cover the whole southern hemisphere, measuring redshifts for 120,000 galaxies and di ....The 6dF Galaxy Survey - Mass and Motions in the Nearby Universe.

A study of vocal tract resonances in the singing voice to develop tools for teaching singing. The voice is our oldest and most widely used musical instrument, but it is incompletely understood because of the difficulty of studying the vocal tract precisely during singing. We shall determine the main techniques used by singers to control and to adapt the acoustic resonances of their vocal tracts. This advance in understanding will enhance Australia's scientific reputation in an area of wide publi ....A study of vocal tract resonances in the singing voice to develop tools for teaching singing. The voice is our oldest and most widely used musical instrument, but it is incompletely understood because of the difficulty of studying the vocal tract precisely during singing. We shall determine the main techniques used by singers to control and to adapt the acoustic resonances of their vocal tracts. This advance in understanding will enhance Australia's scientific reputation in an area of wide public interest. Further, when combined with developments of our novel techniques to operate in real time, it will provide a new tool for students of singing to adjust their resonances and prevent damage to the vocal tract. We shall publish our work not only in the top scientific journals, but also on our popular, multi-award winning web site.Read moreRead less
Parametric Brain Imaging via Modeling and Analysis of Electroencephalographic Signals. Parameters of brain function and physiology will be spatially imaged with high time resolution via their effects on electroencephalographic (EEG) signals, a form of imaging that is impossible with existing methods. This will be achieved by improving existing physiologically-based models of the generation of EEGs and developing analysis tools based on fitting of model predictions to multielectrode EEG data.

Parameters of brain function and physiology will be spatially imaged with high time resolution via their effects on electroencephalographic (EEG) signals, a form of imaging that is impossible with existing methods. This will be achieved by improving existing physiologically-based models of the generation of EEGs and developing analysis tools based on fitting of model predictions to multielectrode EEG data. The results will be used to probe spatiotemporal features of EEGs in normal subjects to explore the underlying fundamental mechanisms and to infer novel parameter variations of practical relevance.Read moreRead less
