Description

Wavefront aberrations, Zernike polynomials, adaptive optics and some applications in vision and ophthalmology

Prof. Vasudevan “Vengu” LakshiminarayananP

Professor of Optometry, Electrical Engineering and Physics, University of Waterloo. SPIE Visiting Lecturer.

Date: Monday 3rd July 2017

Time: 14:00-15:00, refreshments from 13:30

Venue: Building 53, room 4025 (level 4)

Abstract:

Adaptive optics has revolutionized astronomical optics. It has also found applications in vision science. In this talk I will discuss some aspects of adaptive optics, including the history of the subject area, mathematical representation of wavefront aberrations and some applications in vision science. Specifically, I will discuss a computational model of vision to predict visual acuity from a knowledge of wavefront aberrations. A second application will be the use of wavefront aberrations to study tear film breakup. This is important in terms of corneal physiology and design of contact lenses.

Biography:

Prof. Lakshiminarayanan received his Ph.D. from the University of California at Berkeley. He has had research and teaching appointments at UC Berkeley, UC Irvine, Univ. of Missouri -St. Louis and the medical optics industry. Prof. Lakshiminarayanan’s work incorporates a variety of fields, including: vision science, fiber optics, mathematical methods applied to vision and optometry, classical optics including visual optics, geometric optics, aberration theory, etc. and visual psychophysics (both basic and clinical). Prof. Lakshiminarayanan is a Fellow of OSA, SPIE, AAAS, and the IoP.
