Imaging the Propagation of Light Through Scenes at Picosecond Resolution

Imaging the Propagation of Light Through Scenes at Picosecond Resolution

We present a novel imaging technique, which we call femtophotography, to capture and visualize the propagation of light through table-top scenes with an effective exposure time of 1.85 ps per frame.

Jupiter Rising: A Decade of Clos Topologies and Centralized Control in Google's Datacenter Network

Jupiter Rising

We present our approach for overcoming the cost, operational complexity, and limited scale endemic to datacenter networks a decade ago.

Technical Perspective: The Dawn of Computational Light Transport

What would the world look like if we had a chance to observe it with a trillion frame-per-second video camera? "Imaging the Propagation of Light through Scenes at Picosecond Resolution" by Velten et al. represents an audacious…
