1. A system for streak detection in an image scanning device, comprising: an imaging array comprising a plurality of rows or sets of positionally discrete sensors; an interface that transmits image data obtained from each of the plurality of rows or sets of positionally discrete sensors to a comparison unit; and a comparison unit that receives the image data and compares positionally redundant discrete image data obtained from each of a plurality of positionally separated rows or sets of sensors in the imaging array that has been normalized based on the presence of different filtering elements within the positionally separated rows or sets of sensors.
