Novel methods for detecting changes in soft tissue microstructure and biomechanical properties using multi-modality MR imaging. This project will lead to novel methods for studying the internal structure of the soft tissues of the body, such as muscles and brain tissue, and how this is affected by mechanical loading and disease states. The project will thoroughly validate these new methods. This will not only provide new techniques for research use, but lead to improved diagnostic techniques in ....Novel methods for detecting changes in soft tissue microstructure and biomechanical properties using multi-modality MR imaging.

Highly efficient X-ray storage phosphor for medical and scientific imaging. X-rays are invaluable in medical diagnostics. For example, they are widely used in breast screening programs. However,they can cause cancer even at low doses. Consequently there is a global effort to reduce the X-ray dose by exploring more efficient imaging technologies. The present proposal seeks to exploit our recent discovery of a highly efficient storage phosphor that has the potential to facilitate substantial X-r ....Highly efficient X-ray storage phosphor for medical and scientific imaging. X-rays are invaluable in medical diagnostics. For example, they are widely used in breast screening programs. However,they can cause cancer even at low doses. Consequently there is a global effort to reduce the X-ray dose by exploring more efficient imaging technologies. The present proposal seeks to exploit our recent discovery of a highly efficient storage phosphor that has the potential to facilitate substantial X-ray dose reduction; this is of greatest significance to the general population. Also, the phosphor facilitates higher resolution images, a feature that is highly important in scientific imaging. This project may lead to substantial revenue streams for the nation because it taps into a global multibillion dollar industry.Read moreRead less
New Pulsar Instrumentation for Gravitation Wave Detection and Understanding the Emission Mechanism. Millisecond pulsar timing currently provides the most sensitive method of detecting long-period gravitational waves which permeate the Universe. Parkes leads the world in the discovery and timing of millisecond pulsars. This has motivated the development of three new advanced instruments including a cyrogenic dual-band receiver, a very wide-band correlator and a baseband recorder with an in-built ....New Pulsar Instrumentation for Gravitation Wave Detection and Understanding the Emission Mechanism. Millisecond pulsar timing currently provides the most sensitive method of detecting long-period gravitational waves which permeate the Universe. Parkes leads the world in the discovery and timing of millisecond pulsars. This has motivated the development of three new advanced instruments including a cyrogenic dual-band receiver, a very wide-band correlator and a baseband recorder with an in-built supercomputer. We aim to exploit these new technologies to systematically study the pulsar population. We will establish a timing array which can detect gravitational waves, enable GLAST to identify over 100 gamma-ray pulsars and study the pulsar emission mechanism at sub-microsecond time resolution.

The information society in which we live requires increasingly high bandwidth, low cost communications. This project addresses two critically important technologies needed to meet these demands: signal processing devices and antennas. These devices will be designed using three-dimensional photonic crystals, which provide excellent possibilities for low-cost, highly integrated photonic circuits. Working prototypes will be built at microwave frequencies, but due to the scalability of electromagnetic theory these results are also valid in the optical domain. The outcomes of this project will be accurate theoretical models and empirical tests for new technologies that satisfy the future needs of the information society.Read moreRead less

Lithium niobate has the potential to become the silicon of the optoelectronic industry. In order to realise its potential, fundamental problems associated with long term stability and cost of integration need to be solved. This project will develop a new hybrid fabrication platform that circumvents the traditional approaches pursued in the past for introducing waveguides into a lithium niobate chip. This platform will enable the production of robust, low cost light sources for fields as diverse as biotechnology, environmental sensing and displays. This project will lead to new IP that will establish Australia as a leader in this field.Read moreRead less
Laser Micro-Fabrication of Optoelectronic Devices. The project aims to develop new techniques of laser direct-write fabrication of microstructures (1-100 micron in size) in crystalline materials, and to apply these to fabricating periodically-poled nonlinear crystals for optical frequency conversion. These techniques will use laser ablative surface profiling with subsequent electric field poling, and a completely new process of laser temperature profiling with simultaneous field poling, to writ ....Laser Micro-Fabrication of Optoelectronic Devices. The project aims to develop new techniques of laser direct-write fabrication of microstructures (1-100 micron in size) in crystalline materials, and to apply these to fabricating periodically-poled nonlinear crystals for optical frequency conversion. These techniques will use laser ablative surface profiling with subsequent electric field poling, and a completely new process of laser temperature profiling with simultaneous field poling, to write periodic domains in lithium niobate. Such laser direct-write processing is well suited to rapid prototyping and will enable investigation of novel periodically-poled structures, for example, chirped, fanned and multiplexed structures for nonlinear spectral and temporal conversion.Read moreRead less

This research will greatly enhance Australia's position in this breakthrough science.Read moreRead less
Optical parametric amplifiers with exceptional qualities using highly nonlinear optical fibre. Current optical fibre networks use only a fraction of their capacity. This is in part because optical amplifiers with enough bandwidth do not exist. However, it will soon become necessary to exploit all of this capacity. This project will create a new highly nonlinear optical fibre with very low loss and tailored dispersion properties. This will then be used to make an optical fibre parametric ampli ....Optical parametric amplifiers with exceptional qualities using highly nonlinear optical fibre.

However, it will soon become necessary to exploit all of this capacity. This project will create a new highly nonlinear optical fibre with very low loss and tailored dispersion properties. This will then be used to make an optical fibre parametric amplifier with a world record bandwidth, which will enable the full capacity of optical fibre to be exploited.Read moreRead less
