MWSW01 - Canonical scattering problems

Multiple scattering of light is a major impediment to imaging, as the information contained in the wavefront is dispersed among a very large number of degrees of freedom in a deterministic but ultimately unknowable way. Many different approaches to overcome this problem have been put forward, from adaptive optics, to optical gating, to wavefront shaping, each with its own advantages and disadvantages, but the problem is still largely open (especially for the strong scattering regime where all the light is scattered). In this talk I will discuss the possibility to extract part of the scrambled information from the correlations of the resulting speckle patterns, the state of the art, and some recent experimental results.
