Venue: 3.21 Berry Lecture Theatre, HH Wills Physics Labs Building, Tyndall Ave, 3pm
We would like to invite you to attend the Physics Colloquium, which will be held at 3pm on Mondays in 3.21, the Berry Lecture Theatre. The colloquia will be followed by tea and coffee in the staff coffee room. We hope to see you there!
The most imminent event in the series, on the 24th of October, will be presented by Prof. Dave Phillips from the University of Exeter. Click here for a PDF of the abstract: David Phillips Colloquium (PDF, 515kB)
Title: Rendering the opaque transparent
Abstract:
The scattering of light was long thought to be an insurmountable barrier preventing imaging through opaque materials. However, in the last decade or so, a series of pioneering studies showed that it was possible to use a technique called wavefront shaping [1] to characterise and subsequently cancel out complicated scattering effects [2]. Therefore, light that has undergone multiple scattering can be unscrambled to see through opaque media, such as frosted glass, biological tissue, or multimode optical fibres [3]. However, there several major challenges to overcome before wavefront shaping technology can be translated from the laboratory to ‘real-world’ settings. In this colloquium, I will give an introduction to this research area, and outline some of the approaches being developed in my group to tackle outstanding challenges [3-6]. I hope to give a broad perspective on the future of this bright emerging field.
