Abstract
A semiconductor optical image sensor is constructed particularly as a CCD-structure having a linear or two-dimensional array configuration with parallel or serial read-out. The CCD-structure is combined with an avalanche diode structure arranged on one side of the semiconductor or in laterally spaced locations to allow an optically controllable amplification of the image signal in the image sensor by an avalanche effect.
