Fig. 1: Edge-resolved transient imaging scenario and procedure.
From: Seeing around corners with edge-resolved transient imaging
a Positions along an arc centered on the occluding wall edge are illuminated sequentially by a pulsed laser. b A histogram of photon counts over time is collected for each laser illumination spot. The measured histograms contain photons reflected from both the hidden scene and the visible side. c Taking differences between sequential histograms on average yields returns originating only from a small wedge within the hidden scene. d A hidden area reconstruction using the collection of histogram differences.
