Join the OSA Vision Technical Group for a three part workshop exploring chromatic aberrations in vision. This series will bring to light recent advances in the measurement and correction of chromatic aberrations in the eye for vision and imaging applications. In addition, the talks will explore future directions in the field.

In this first part of the workshop, Prof. Melanie Campbell from the University of Waterloo will deliver her keynote talk ‘Aberrations of the eye: implications to eye growth, vision and imaging.' Both chromatic and monochromatic aberrations have significant relevance in eye growth, vision and high-resolution retinal imaging. In this talk, you will learn about the background of the optics of the eye, a description of monochromatic wavefront aberrations and the factors affecting these aberrations including age and accommodation. The resulting monochromatic image quality and chromatic aberration in the eye has importance in eye growth, vision and imaging.

About the Presenter:  Melanie C. W. Campbell, University of Waterloo

Melanie C. W. Campbell is currently a professor in the Department of Physics and Astronomy, University of Waterloo and is cross-appointed to the School of Optometry and Vision Science and to the Department of Systems Design Engineering. She obtained a B.Sc. degree in Chemical Physics from the University of Toronto and an M.Sc. degree in Physics from the University of Waterloo. An interest in the optical properties of the eye led to a Ph.D. from the Australian National University awarded jointly by the John Curtin School for Medical Research and the Research School of Physical Sciences. After 2 years as a postdoctoral fellow at CSIRO in Australia, a University Research Fellowship from the Natural Sciences and Engineering Research Council of Canada enabled Professor Campbell to join the University of Waterloo.

Prof. Campbell collaborated in the first real-time images of cone photoreceptors, using adaptive optics and she uses polarization imaging to make invisible structures visible. Imaging applications include a biomarker of Alzheimer’s disease, using the retina as a window on the brain. She undertakes research on the optical quality of the eye and improved imaging of its structures. She studies eye development, eye disease and linear and nonlinear optics of the eye. Campbell is known for her work on the gradient index optics of the crystalline lens, its changes with ageing and effects of visual experience on its refractive index distribution. Recently she has discovered putative optical signals to guide eye growth.

Professor Campbell is a Fellow of the Optical Society, a former president of the Canadian Association of Physicists, received the 2004 Rank Prize in Optoelectronics, the 2014 CAP INO Medal for Outstanding Achievement in Applied Photonics and in 2015, she was awarded the OCUFA Status of Women Award of Distinction. She has also co-founded two companies, Biomedical Photometrics Inc, now Huron Technologies and LumeNeuro.
