Peripheral aberrations of the human eye. This project will benefit Australia from several perspectives. It will make an important contribution to understanding limitations to peripheral vision of the eye, particularly as a result of refractive surgical intervention. This is important because many Australians will require such surgery. Being able to better measure and correct peripheral aberrations will lead to improved imaging of the eye and thus contribute to improved detection and diagnosis of ....Peripheral aberrations of the human eye. This project will benefit Australia from several perspectives. It will make an important contribution to understanding limitations to peripheral vision of the eye, particularly as a result of refractive surgical intervention. This is important because many Australians will require such surgery. Being able to better measure and correct peripheral aberrations will lead to improved imaging of the eye and thus contribute to improved detection and diagnosis of ophthalmic disease. The study will benefit ophthalmologists, optometrists, and engineers involved in designing visual instruments. This project will provide training in adaptive optics for graduate students not available in any other Australian institution.Read moreRead less

Relationship of retinal directionality to human retinal anatomy variations. This project aims to improve measurement of retinal directionality, which is the reduction in brightness when a light beam’s entry into the human eye is shifted from the centre to the edge of the pupil. This influences retinal image quality and can be used to measure changes in shape of the peripheral eye. This project will apply advanced technologies in holography, and heads-up displays to explore how retinal directiona ....Relationship of retinal directionality to human retinal anatomy variations. This project aims to improve measurement of retinal directionality, which is the reduction in brightness when a light beam’s entry into the human eye is shifted from the centre to the edge of the pupil. This influences retinal image quality and can be used to measure changes in shape of the peripheral eye. This project will apply advanced technologies in holography, and heads-up displays to explore how retinal directionality changes during accommodation (focusing). The expected outcome is improved understanding of retinal stretching changes during focusing. The benefit is that the project will lead to advancements in retinal imaging.Read moreRead less
Removing the blinkers: a wider study of the human eye. Peripheral aberrations, wide-field retinal imaging and optical parameters. This project will study peripheral (side vision) optics of the human eye and its role in the limits of visual performance. This will improve ocular measurements and contribute towards improved diagnosis and treatment of ocular diseases and short-sightedness.
Advanced methods for intraocular imaging. The ability to image the retina of the human eye at high resolution is fundamental to improving understanding of ocular physiology, ocular optics and disease diagnosis. This project applies the relatively new application of active optics to vision science. This project will investigate the advantages of using new beam shaping techniques for characterising the optics of the eye, improving retinal imagery and improving fixation stability.

This project applies the relatively new application of active optics to vision science. This project will investigate the advantages of using new beam shaping techniques for characterising the optics of the eye, improving retinal imagery and improving fixation stability. This project will achieve three-dimensional holography of human eyes and develop holography plates for correcting the aberrations of eyes. Expected outcomes are not-before experienced resolution images of the retina and better understanding of the optical characteristics of the refractive surfaces and media in the eye.Read moreRead less
Developing tests for the early detection of eye disease. Australians have a tradition of innovative design in perimetry. A good example being the Frequency Doubling Technology produced from work performed at the Australian National University. This technology, however, is manufactured by an overseas company (Welch Allyn, NY, USA). The Medmont company is a local perimeter manufacturer and we hope to improve their product with innovative design to yield a distinct marketing advantage.

A good example being the Frequency Doubling Technology produced from work performed at the Australian National University. This technology, however, is manufactured by an overseas company (Welch Allyn, NY, USA). The Medmont company is a local perimeter manufacturer and we hope to improve their product with innovative design to yield a distinct marketing advantage. We will consider the fundamental issues underlying cone-interactions and methods that stress retinal function. We believe that this approach will have advantages over conventional techniques and prove more sensitive for the early detection of eye disease. However, this is a high risk venture requiring substantial developmental cost and technical commitment by the company. Successful innovation will enhance the company's international penetration, continue the trend for Australians to be seen as leaders in this field and have impact on eye care.Read moreRead less

This project aims to develop a new generation flat screen that is lighter, more efficient and with higher resolution by replacing the traditional liquid crystals (LCs) with metasurfaces that are 100-times thinner than LCs. Metasurfaces are arrays of engineered dielectric and semiconductor nanoparticles, with extraordinary characteristics. The expected outcomes will lead to flat screens with resolution enhanced by 100 times and energy consumption reduced by half, as compared to current LC-based displays (e.g. LCD and LED). This novel technology will revolutionise the dimension and performance of displays and secure Australia's position in the billion dollar market of flat displays.
