Congratulations to Prof Heike Ebendorff-Heidepriem for being elected as a Fellow Member of The Optical Society (OSA) at the Society’s September 2017 Board of Directors meeting.
Founded in 1916, OSA is the leading professional association in optics and photonics, home to accomplished science, engineering, and business leaders from all over the world. Through world-renowned publications, meetings, and membership programs, OSA provides quality information and inspiring interactions that power achievements in the science of light.
Prof Ebendorff-Heidepriem is being honored specially for ground breaking science contributions to the field of optical glasses and fibers.
Making the first two pages in the “Making a difference – Outcomes of ARC supported research” publication, Detecting Gravitational Waves & Smart Needle To Make Brain Surgery Safer were proudly featured in the “Understanding Our World and Translating Fundamental Research” section. This publication is a snapshot of some of the outstanding research outcomes derived from research projects funded by the Australian Government through the Australian Research Council (ARC) National Competitive Grants
Detecting Gravitational Waves – the most exciting discovery in fundamental physics for decades was firstly announced in 2016 which has opened a new window in astronomy. These discoveries have opened up new possibilities in exploring the universe through its most enigmatic objects: black holes, while at the same time testing our current understanding of the physical laws underpinning the universe. Prof Peter Veitch and A/Prof David Ottaway are leading the Research being carried out at the University of Adelaide node of the new ARC Centre of Excellent for Gravitional Wave Discovery, OzGrav.
Smart Needle To Make Brain Surgery Safer project lead by Prof Robert McLaughlin had developed a revolutionary tiny imaging probe encased within the brain biopsy needle to allow surgeons to avoid at-risk blood vessels which can potentially fatal. This device contains a tiny fibre-optic camera using shining infrared light and combined with smart image processing software to alert surgeon potentially damaging vessels. Professor Christopher Lind, Consultant Neurosurgeon successfully did a pilot trial with 12 undergoing neurosurgery.
Congratulations to both LIGO and Miniprobes team!

Despite the fact that dragonflies can’t drive cars, understanding how their brains work is improving selective attention for artificial vision systems, for applications such as driveless cars.
A recent study by Dr Steven Wiederman and published in eLife, demonstrated how dragonflies are highly efficient predators due to the highly complex nature of their brain. Specifically, cells in their brains, called Small Target Motion Detectors, can predict the direction and location of its prey.
Further understanding of such complex neurological systems can be applied to autonomous robots and driverless cars.

Dr Chris Perrella (Precision Measurement Group) was recently awarded a Global Connections Fund Priming Grant. The purpose of the grant is to facilitate collaborations between Australian small to medium sized enterprises (SMEs) and researchers.
This Project will develop a compact high-performance optical clock for ultra-precise timing signals by bringing together Australia’s foremost precision measurement laboratory at the Institute for Photonics and Advanced Sensing (IPAS), the University of Adelaide, and links it to the world’s leading company in optical precision measurement technology, Menlo Systems GmbH.
The compact high-performance optical clock has potential applications in: communication networks; telecommunications; global positioning systems (GPS); and inertial navigation systems.

An IPAS research team led by Dr Erik Schartner has developed an optical fibre probe that distinguishes breast cancer tissue from normal tissue – potentially allowing surgeons to be much more precise when removing breast cancer.
The device could help prevent follow-up surgery, currently needed for 15-20% of breast cancer surgery patients where all the cancer is not removed.
Published today in the journal Cancer Research, the researchers in the ARC Centre of Excellence for Nanoscale BioPhotonics (CNBP), the Institute for Photonics and Advanced Sensing, and the Schools of Physical Sciences and Medicine, describe how the optical probe works by detecting the difference in pH between the two types of tissue. The research conducted with our partners Prof. Grantley Gill at with the Breast, Endocrine and Surgical Oncology Unit at the Royal Adelaide Hospital, Dr Deepak Dhatrak of SA Pathology and Prof David Callen, Director of the Centre for Personalised Cancer Medicine at the University of Adelaide.
“We have designed and tested a fibre-tip pH probe that has very high sensitivity for differentiating between healthy and cancerous tissue with an extremely simple – so far experimental – setup that is fully portable,” says project leader Dr Erik Schartner, postdoctoral researcher at the CNBP at the University of Adelaide.
“Because it is cost-effective to do measurements in this manner compared to many other medical technologies, we see a clear scope for this technology in operating theaters.”
Current surgical techniques to remove cancer lack a reliable method to identify the tissue type during surgery, relying on the experience and judgement of the surgeon to decide on how much tissue to remove. Because of this, surgeons often perform ‘cavity shaving’, which can result in the removal of excessive healthy tissue. And at other times, some cancerous tissue will be left behind.
“This is quite traumatic to the patient, and has been shown to have long-term detrimental effects on the patient’s outcome,” Dr Schartner says.
The optical fibre probe uses the principle that cancer tissue has a more acidic environment than normal cells; they produce more lactic acid as a byproduct of their aggressive growth.
The pH indicator embedded in the tip of the optical probe emits a different colour of light depending on the acidity. A miniature spectrometer on the other end of the probe analyses the light and therefore the pH.
“How we see it working is the surgeon using the probe to test questionable tissue during surgery,” says Dr Schartner. “If the readout shows the tissues are cancerous, that can immediately be removed. Presently this normally falls to post-operative pathology, which could mean further surgery.
The researchers currently have a portable demonstration unit and are doing further testing. They hope to progress to clinical studies in the near future.
Minister for Defence Industry, The Hon Christopher Pyne MP today announced seven Australian organisations would receive Australian Government funding of $14.7 million to develop and demonstrate innovative technologies to enhance Defence capability, as part of the Government’s $1.6 billion investment in defence innovation.
IPAS researchers Prof Andre Luiten, A/Prof John Hartnett and A/Prof Martin O’Connor are the research leaders of one of these projects. Their project is to develop Ultra-High Quality Signal Generation for Over the Horizon Radar. The project aims to upgrade the overall performance of the Jindalee Operational Radar Network (JORN), through a performance upgrade of its essential sub-systems. This will improve overall detection of targets.
