OSA Vision Technical Group Workshop Part III: Chromatic Aberrations in Vision
Hosted By: Vision Technical Group
02 July 2020 12:00 - 13:00Eastern Time (US & Canada) (UTC - 04:00)
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.
Part III of this workshop will feature talks from Ramkumar Sabesan and Enrique Josua Fernandez.
Measuring and Correcting Chromatic Aberration for Adaptive Optics Vision Testing and Imaging, presented by Ramkumar Sabesan will cover:
- Impact of chromatic aberration on high-resolution retinal imaging and vision testing
- Subjective and objective methods to measure chromatic aberrations in the eye
- Examples of vision science experiments that benefit from correction and control of chromatic aberration.
Chromatic Aberration Correction for Retinal Imaging, presented by Enrique Josua Fernandez will cover:
- A short introduction about chromatic aberration in the eye
- Why correcting chromatic aberration in Ophthalmoscopy is critical for some imaging modalities, and how it was initiated
- How chromatic aberration can be compensated: different methods, and some results
- Latest trends in the correction, future and some applications beyond imaging
About the Presenters:
Ramkumar Sabesan, University of Washington
Dr. Sabesan earned his Bachelor’s degree in Engineering Physics from the Indian Institute of Technology, Delhi and his Ph.D. in Optics at the Institute of Optics and Center for Visual Science at the University of Rochester. Following his doctorate, he did a postdoctoral fellowship at the School of Optometry at University of California, Berkeley studying the retinal basis of color perception using advanced high-resolution imaging, before joining the faculty at University of Washington Department of Ophthalmology. At UW, Dr. Sabesan holds adjunct appointments in the departments of Bioengineering and of Biological Structure and is a member of the Graduate program in Neuroscience and University of Washington Institute for Neuroengineering. His lab’s basic science and translational research questions span the interface between optical imaging, neuroscience and ophthalmology and uses a combination of adaptive optics-based technologies, quantitative phase imaging, visual psychophysics, and computational approaches to pursue them. In addition to extramural funding from the National Eye Institute, Dr. Sabesan’s research has been supported by the Burroughs Wellcome Fund Career Award at the Scientific Interfaces, the Research to Prevent Blindness Career Development Award, the Alcon Research Institute Young Investigator Award and an Individual Investigator Grant from the Foundation for Fighting Blindness.
