MODELING OF NON-UNIFORMITY PHOTOSENSITIVITY OF PIXELS OF A CCD LINEAR IMAGE SENSOR

The results of modeling the process of forming an electrical signal from the output of a CCD linear device, taking into account the photo response non-uniformity of pixels, are presented. A quantitative assessment of the error introduced by the uneven photosensitivity of pixels into the calculation of the coordinates of the light spot by the centroid method is given.
