A team of researchers has captured high-speed footage of a light pulse traveling in three dimensions as it bounced off of a series of mirrors [1]. Previous efforts have only recorded pulses moving in 2D. The team’s achievement was made possible by a new high-resolution, high-speed camera. The demonstration shows the emerging capabilities of high-speed image sensors and hints at potential applications in technologies such as time-resolved medical imaging and car safety features.
