Abstract:
Polarization diverse images are generated at the end of a multimode fiber using spatial light modulators to completely characterize propagation through the fiber in terms of the eigenmodes.

Coherent control of the total transmission of light through disordered media

We demonstrate order of magnitude coherent control of total transmission of light through random media by shaping the wave front of the input light. To understand how the finite illumination area on a wide slab affects the maximum values of total transmission, we develop a model based on random matrix theory that reveals the role of long-range correlations. Its predictions are confirmed by numerical simulations and provide physical insight into the experimental results.

Imaging through opaque layers

 TedxTwenteu - Simon Huisman

Friday, 11 October, 2013

Abstract:
Simon Huisman, a recent doctoral graduate with both the COPS and OS group at the University of Twente, talks about an interesting phenomenon which earned the COPS group a picture on the cover of Nature: imaging through opaque layers. With a live setup Simon shows us that with the aid of lasers it is possible to look through opaque objects (e.g. milk or paper) and will he talk about the consequences of this new technology.
