OPTICAL IMAGING IN BIOLOGICAL AND COMPLEX MEDIAPrincipal Investigator : Sylvain Gigan
The group deals with light propagation in complex media, mainly disordered photonic systems where light is scattered in a very complex way, such as paint layers, paper, or biological tissues. Multiple scattering of coherent light generates extremely complex interference patterns, called speckle. But despite the enormous complexity of the scattering process, we can exploit and control light propagation, in particular thanks to spatial light modulators. Our approach is particularly interesting for imaging, light-matter interactions, signal
processing, but also as windows to understand subtle mesoscopic physics effects.
