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.Premio Tesi di dottorato.Imaging light transport at the femtosecond scale Mathematical physicsProblems, exercises, etcMathematical physicsData processingMathematical physicsProblems, exercises, etc.Mathematical physicsData processing.530.15Pattelli Lorenzo1261783NjHacINjHaclBOOK9910571731203321Imaging light transport at the femtosecond scale2941529UNINA
