Infrared sensors and systems are finding increasing use in Australia's core industries: particularly defence, mineral exploration, environmental monitoring, precision agriculture, homeland security, and medical diagnostics. Due to the reduced cooling requirements, the Infrared detector structures to be investigated in this project have the potential to deliver high performance infrared technology at a significantly lower cost and, hence, widening its applications.

The ability of infrared detectors to directly sense the thermal output of an object has applications in medicine, search and rescue, bushfire detection and in the defence and surveillance industries. The highest performing infrared detectors are photon detectors based molecular beam epitaxy (MBE) grown HgCdTe. The primary aims of this project relate to the fundamental understanding of p-type doping in MBE grown HgCdTe, a current and major difficulty in HgCdTe technology, and the use of such p-type MBE grown layers in conjunction with a newly developed plasma process based n-p junction formation technology to realise novel and innovative infrared detector structures. Such structures would have the ability to revolutionise the use of HgCdTe in infrared detectors and focal plane array applications.Read moreRead less
New multiplexed optical read-out technologies for micromachined cantilever sensor arrays. Passive sensing of chemical and biological agents is an essential capability in fields as diverse as national security, agriculture, mining and medicine. In many cases, generic sensing (e.g. are there pesticides present) as well as specific sensing (which pesticide) are both important. While sensors based on micro-electromechanical systems (MEMS) have shown extremely high performance at low cost, they have ....New multiplexed optical read-out technologies for micromachined cantilever sensor arrays. Passive sensing of chemical and biological agents is an essential capability in fields as diverse as national security, agriculture, mining and medicine. In many cases, generic sensing (e.g. are there pesticides present) as well as specific sensing (which pesticide) are both important. While sensors based on micro-electromechanical systems (MEMS) have shown extremely high performance at low cost, they have been limited to detection of a specific substance. Success in this project will make low cost generic MEMS-based sensors a reality, allowing, for the first time, wide-spread use of sensitive sensing systems in applications such as farming, container transport security, general medical practice and national security.Read moreRead less

Imaging of properties of coherent elastic light scattering from turbid biological media. Imaging with coherent, elastically-scattered light for visualisation of thick-tissue morphology in vivo, or of cells buried deep in a turbid medium, remains a major challenge. We adopt an alternative approach of imaging of properties of light scattering based on regarding cellular tissue as a spatially-varying refractive-index continuum which encodes scattered light. We propose new methodologies to infer t ....Imaging of properties of coherent elastic light scattering from turbid biological media. Imaging with coherent, elastically-scattered light for visualisation of thick-tissue morphology in vivo, or of cells buried deep in a turbid medium, remains a major challenge. We adopt an alternative approach of imaging of properties of light scattering based on regarding cellular tissue as a spatially-varying refractive-index continuum which encodes scattered light. We propose new methodologies to infer tissue state and morphology indirectly based on phase delay, speckle, and angle-resolved scattering. We will break new ground in correlating the structure and function of in situ epithelial tissue and cells to light scattering enabling, e.g., the detection of mitosis and apoptosis in cells buried in thick, turbid media, and of cancers and precancers in vivo.Read moreRead less

We propose to continue our research into the biomedical imaging technique of optical coherence tomography by making substantial new advances in the key areas of ultra-broad bandwidth operation, coincident confocal gate scanning, and dispersion compensation. These advances are aimed at improving resolution to the 1-5 micron range, which should allow a breakthrough to sub-cellular in vivo imaging, making visible sample histology in situ, which is currently not possible. We also plan to make advances in the key area of scanning delay line technology by employing acousto-optics in OCT for the first time. Acousto-optics conveys advantages in no-moving-parts, scan-speed and accuracy.Read moreRead less

This project brings together an international, multi-disciplinary team to develop innovative, high-resolution techniques to identify diseased tissue. Success will result in a new medical imaging technique allowing clinicians to quantify the mechanical properties of tissue, effectively creating a high-resolution image of what the tissue 'feels' like. This may help them to more accurately identify cancerous tissue during surgery and reduce rates of recurrence. It could aid in tissue engineering and regeneration and will provide a new database of tissue mechanical properties. The project will position Australia as a leader in this newly developing medical imaging technology, with significant potential for commercialisation.Read moreRead less
