Light-in-flight: transient imaging using photonic mixer devices

Felix Heide, Matthias B. Hullin, James Gregson, Wolfgang Heidrich

Abstract: Transient imaging is a recent imaging modality in which short pulses of light are observed "in flight" as they propagate through a scene. Transient images are useful to help understand light propagation in complex environments and to analyze light transport for research and many practical applications. Two such examples are the reconstruction of occluded geometry, i.e. "looking around a corner", [Velten et al. 2012] or measuring surface reflectance [Naik et al. 2011].
