FIELD: physics.
SUBSTANCE: photodetector target has the shape of a circular ring, and lines of photosensitive elements and lines of light-shielded elements are arranged along radial directions from the imaginary centre of the circular ring to its outer periphery and an output shift register located there, which is "circular". The number of elements in each "circular" row of the photodetector region is equal to the number of elements in the "circular" shift register.
EFFECT: reducing redundant channel bandwidth for communication of the television camera with a server.
