Figure 1: Intensity distribution of light randomly scattered many times inside a disordered structure, called speckle.
Figure 2: Multiple scattering in a disordered material is fully elastic, meaning that the image information is not lost when light passes through the structure; that is, the multiple scattering process is completely reversible.
