Abstract
The optics of the human eye are not perfect, suffering from monochromatic aberrations. The importance of aberration control in imaging structures at the rear of the eye will be outlined. Both resolution and contrast of images are improved when the aberrations are lowered or when polarization imaging is used. Aberrations are measured using a technique from astronomy that samples light reflected out of the eye with a lenslet array. Individual photoreceptors at the rear of the eye can be resolved. Improved imaging with a confocal scanning laser ophthalmoscope has potentially large implications to the diagnosis and treatment of ocular disease and to the understanding of normal and abnormal ocular development.

About the Speaker
Melanie Campbell is a Professor of Physics and Optometry and a University Research Chair in Physics at the University of Waterloo. Campbell is internationally known for her research in the optical quality of the eye and ophthalmic imaging. She has extensive retinal imaging expertise including the first real-time images of cones at the rear of the eye, and patents in polarization imaging which will improve imaging in ophthalmoscopy and microscopy. Her research encompasses animal models of ocular development and disease, the crystalline lens and clinical research imaging of the eye. Campbell is a Fellow of the Optical Society of America, and the Institute of Physics. She is President of the Canadian Association of Physicists. Campbell shared the 2004 Rank Prize in optoelectronics for research "where an initial idea has been carried through to practical applications that have, or will, demonstrably benefit mankind."
