ABSTRACT:
A photoelectric sensor array is labelled by accumulating charge, preferably charge from a dark current, in at least a portion of the sensor array and reading out the accumulated charge to form an image to determine locations of atypical pixels in the portion of the sensor array. A signature of the sensor array is generated from the locations of atypical pixels and stored. The array is subsequently identified by re-accumulating charge in the portion of the array to form a signature based on the atypical pixels for comparison with the stored signature.
