Join for a special seminar presentation with Austin Roorda, Professor, UC Berkeley, Herbert Wertheim School of Optometry & Vision.
Seminar abstract
Humans possess an exquisite ability to immediately generate rich and accurate percepts of a viewed scene in color, space, motion and depth. The process is so effortless that we often take it for granted, but like most lines of scientific investigation, the closer you look, the more interesting it gets.
An ability to hack the visual system and directly control the factors (optical blur, eye motion, activation of three types of cone photoreceptor cells) that govern the sensory inputs that inform our percepts can offer some insight into this remarkable process. Systems that combine adaptive optics, high-speed tracking, and precise aberration-corrected light delivery to the retina allow us to do just that. I will describe our most recent systems, their capabilities and applications. Specifically, I will focus on experiments that investigate spatial vision [the beneficial role of eye motion for visual acuity] and color vision [how signals from the three cone types are used to generate percepts of color]. I will end with some discussion of how these technologies are being translated for clinical applications.
