DESCRIPTION:Transient imaging is an all-optical gating technique that captures the\nevolution of the spatial profile of diffusing light with sub-picosecond\nresolution, in transmission or reflection and with polarization\nsensitivity. Combining the temporal, spatial and polarization domains\ngives access to transport quantities that remain hidden to any of them\ntaken alone: the tensor diffusion coefficient of structurally\nanisotropic media, and the early-time depolarization dynamics that\nreveal single-scattering properties even deep in the diffusive regime.\nThe same observables also offer a route to three-dimensional Anderson\nlocalization of light, since the transverse spreading of the transmitted\npattern is a direct signature of the diffusive-to-localized transition\nand, unlike time-of-flight measurements, is insensitive to homogeneous\nabsorption and fluorescence. I will show preliminary measurements on\nmetallic and high-index dielectric scattering media, with the prospect\nof extending it to amorphous correlated dielectric networks.\n
