Relativistic Ultrafast Rendering Using Time-Of-Flight Imaging

We capture ultrafast movies of light in motion and synthesize physically valid visualizations. The effective exposure time for each frame is under two picoseconds (ps). Capturing a 2D video with this time resolution is highly challenging, given the low signal-to-noise ratio (SNR) associated with ultrafast exposures, as well as the absence of 2D cameras that operate at this time scale. We re-purpose modern imaging hardware to record an average of ultrafast repeatable events that are synchronized to a streak tube, and we introduce reconstruction methods to visualize propagation of light pulses through macroscopic scenes.
