Conventional CMOS Image sensors have been increasing their speed over the years, but they are now plateauing around 20 Gpixel per second. This pixel rate corresponds to a megapixel sensors acquiring images at 20,000 fps (frames per second).
Other architectures are used to achieve higher speed. Burst mode CMOS sensors can record a reasonably high number of frames at pixel rate in excess of a few Tpixel/sec. This corresponds to a few millions of frames per second at megapixel resolution! See IMASENIC paper for more details.
In Time Pixel Sensors (TPM) pixels are arranged in groups to produce a high-speed movie, in a sort of temporal RGB coding. In time-stamping sensors, single photon or single shot detection is achieved with time resolutions that can be significantly better than 1 ns when Single Photon Avalanche Diode (SPAD) are used.
IMASENIC has experience with all of these architectures and is supporting customers for their fastest applications.
