Outline of Final Research Achievements

We have developed an ultra-high-speed camera performing 200M frames per second, which is based on a fusion of optics (multi-aperture optics), electronics (ultra-high-speed time-resolving charge modulation pixel), and processing (compressive sampling). Our scheme has solved the bottleneck of the ultra-high-speed image sensors and achieved the highest frame rate among the silicon image sensors by utilizing coded shutters, multiple exposure, and signal reproduction. Furthermore, higher capturing efficiency that more frames are reproduced than the captured frames is realized than that of the conventional ultra-high-speed cameras.
