Light in Complex Media
Multiple scattering of light is omnipresent in our environment. It is for instance responsible for the white color of clouds, snow, paper or milk. Who did not get disoriented in a thick fog where all light sources become completely blurred? Standard imaging techniques are ineffective in such media. Looking through turbid media is therefore an important challenge in many fields, such as biomedical imaging, soft matter study as well as paint characterization.
This course proposes an in depth study of the fundamentals of light propagation in disordered scattering media. It aims at giving different theoretical and experimental tools to deal with light scattering. It offers an overview of the modern experimental techniques of investigation of these complex media and the state of the art of the research in the field.
