Abstract

Rayleigh proposed a spatial resolution limit when resolution of lenses approached to the limit. The frame rate of image sensors has been exponentially increasing. A simulation study showed a silicon image sensor can achieve the frame interval less than 200 ps (about 1010 fps) with an existing 130 nm technology. It’s time to search the ultimate high speed. An expression of the theoretical highest frame rate of silicon image sensors is derived. For example, the temporal resolution limit for green light of 550 nm is 11.1 picoseconds; the inverse, the theoretical highest frame rate is 90.1 Gfps (about 1011 fps).
