摘要:The first digital high-speed video camera was developed in 1989. For about thirty years since then, the highest frame rate has exponentially increased from about 103 fps to 108 fps, and will reach 109 to 1010 fps in the very near future. The evolution has been supported by successive innovations of the technology, such as: (1) since the middle of 1980s, solid-state image sensors enabling parallel and partial readout, (2) since 1989, digital high-speed video cameras with a separate digital recording box, (3) since 1996, burst image sensors with pixels each equipped with the in-situ memories or the pixel-based memories in the periphery of the sensor chip, and (4) since 2011, backside-illuminated and 3D-stacked high-speed image sensors. The history is reviewed, including on-going works. Ultimately, how fast can silicon image sensors operate? The solution is purely theoretically derived and presented.
