Compressive Coded Rotating Mirror Camera for High-Speed Imaging

We develop a novel compressive coded rotating mirror (CCRM) camera to capture events at high frame rates in passive mode with compact instrument design fraction of the cost compared other high-speed imaging cameras. Operation CCRM is based on amplitude optical encoding (grey scale) and continuous sweep across low-cost detector using motorized system which can achieve single pixel shift between adjacent frames. Amplitude overlapping enable number captured frames temporal resolution without making sacrifices spatial resolution. Two sets dynamic scenes have been up 120 Kfps rate both monochrome colored scales experimental demonstrations. The obtained heavily compressed data from experiment are reconstructed optimization algorithm under sensing (CS) paradigm highest sequence depth 1400 exposure has achieved compression ratio 368 CS-based technologies. Under similar conditions 700× faster than conventional devices could reach 20 Gfps.
