Abstract

In modern digital imaging systems, the recording of high-speed, high-resolution video has been hindered by the limited data transfer bandwidth of electronics. Here we demonstrate ultrahigh-pixel-rate compressed photography using time delay integration (TDI) in which both the spatial and temporal resolutions are greatly enhanced. A dynamic scene is spatially encoded with a pseudo-random pattern, temporally modulated by the TDI camera, and streamed to a host computer for post-processing. The system can record a 0.85-megapixel video at a 200kHz frame rate (170 gigapixels per second). The corresponding pixel rate is two orders of magnitude greater than that of a conventional camera.
