This webinar, hosted by the OSA Applications of Visual Science Technical Group, will give an overview of adaptive optics applied to vision science and will be presented by three speakers from the field.

The topics presented in this webinar will include:

Introduction to Adaptive Optics (Dr. Karen Hampson, University of Oxford)

  • What is adaptive optics?
  • Why we need adaptive optics (ocular aberrations)
  • How it works
  • How to design (layout) of a basic system


Adaptive Optics for Testing Vision and Visual Function (Dr. Silvestre Manzanera, Universidad de Murcia, Spain)

  • Typical layout of an adaptive optics system for testing vision and visual function
  • Selecting the display for the stimulus
  • What we can learn about vision using adaptive optics


Adaptive Optics for Retinal Imaging (Dr. Laura Young, University of Oxford)

  • Typical layout of an adaptive optics system for retinal imaging
  • Selecting the retinal imaging camera
  • What we can learn about the retina using adaptive optics


What You Will Learn:

  • You will learn the basics of adaptive optics and what we can learn from it about the visual system.

Who Should Attend:

  • This webinar is recommended for graduate students and researchers who are new to the field.

About the Presenters:

Karen Hampson, University of Oxford

Dr. Karen Hampson completed her PhD in Adaptive Optics for Vision Science at Imperial College London in 2004. During her PhD she developed an adaptive optics system to study the effect of higher-order aberrations on accommodation control. After that, she continued to work in this area at the University of Bradford, Department of Optometry, where she developed several adaptive optics systems. She has published in a variety of journals and is publishing a book titled “Introduction to Adaptive Optics for Vision Science” to be released by CRC Press in autumn 2019. Karen joined the Department of Engineering Science at the University of Oxford in August 2017, where she develops adaptive optics systems for microscopy and satellites.

 

 

Silvestre Manzanera, Universidad de Murcia

Dr. Silvestre Manzanera works on adaptive optics (AO) applied to the human eye. In particular, he helped in the development of adaptive optics visual simulators (AOVS). This is an instrument that requires a combination of different technologies, photonics, instrumental optics, electronics and control theory, to simulate vision under carefully controlled optical conditions. This technology had immediate applications in the design and testing of new ophthalmic devices such as contact lenses or intraocular lenses. He also focused on the design and testing of optical solutions to correct for presbyopia. Since then, the design, improvement and use of this instrument for both basic and applied research has been one of the topics in his scientific career. The strong applicability of the AOVS led him to participate in an important number of projects funded by international companies that resulted in a significant number of publications and the improvement of ophthalmic solutions currently in the market. He was also directly involved in the development, as a co-founder, of Voptica S.L., a spin-off company to further develop commercially ocular adaptive optics. In the last years, he continued with the development of a new generation of AOVS that is capable of testing vision simultaneously on both eyes increasing the variety and number of experiments that were performed. He has also participated in other experimental projects in optoelectronics for biomedical applications.

 

Laura Young, University of Oxford

Dr. Laura Young is a Career Development Lecturer in the Department of Experimental Psychology at the University of Oxford. Her research lies at the interface between the fields of optical microscopy and vision, studying the impact of optical aberrations on visual performance and on retinal imaging. In collaboration with the Centre for Advanced Instrumentation at Durham University she has developed an adaptive optics scanning laser ophthalmoscope for imaging the human retina in vivo with cellular resolution. This instrument is providing insights into the mechanisms underlying normal visual perception and into the time-course of inherited retinal disease.
