For very thick and turbid media, indeed, light eventually propagates in a 'diffusive' way, i.e. similarly to how tea infuses through hot water. Frequently though, a material is neither perfectly opaque nor transparent and the simple diffusion model does not hold. In this work, we developed a novel optical-gating setup that allowed us to observe light transport in scattering media with sub-ps time resolution. An array of unexplored aspects of light propagation emerged from this spatio-temporal description, unveiling transport regimes that were previously inaccessibile due to the extreme time scales involved and the lack of analytical models. 410 0$aPremio Tesi di dottorato. 517 $aImaging light transport at the femtosecond scale 606 $aMathematical physics$xProblems, exercises, etc 606 $aMathematical physics$xData processing 615 0$aMathematical physics$xProblems, exercises, etc. 615 0$aMathematical physics$xData processing. 676 $a530.15 700 $aPattelli$b Lorenzo$01261783 801 0$bNjHacI 801 1$bNjHacl 906 $aBOOK 912 $a9910571731203321 996 $aImaging light transport at the femtosecond scale$92941529 997 $aUNINA
