Abstract
When an array of photodetecting elements has to be calibrated, normally a reference surface is scanned. Yet the reference surface is not an ideal surface and likely may include scratches or dust particles so that the signals read out from the array have to be corrected. A method and system of correction are provided in which the statistical distribution of the signals read out over the surface is evaluated for each photodetector. By this evaluation, dust and scratches can be disregarded before calculating a mean value representative of the sensitivity of each individual element.
