Research
Overview
|
| Williams uses advanced psychophysical, anatomical,
and imaging techniques to study how the structure of the eye
and brain affects visual experience. He has developed laser
interferometers that can produce very fine patterns on the retina,
much finer than could ever be imaged there under ordinary viewing
conditions. This device allowed him to investigate processing
by the retina and brain without any blurring by the optics of
the eye. A current research project uses advanced imaging techniques,
such as adaptive optics, to explore the optical quality of the
eye and the organization of the human retina. He developed a
camera that can acquire sharper images of the retina than has
been possible previously, sharp enough to resolve single cone
photoreceptors for the first time in the living human retina.
Another project has provided the first color images of the primate
photoreceptor mosaic that allow one to distinguish the three
cone types responsible for human color vision. |
