Abstract
The device includes at least two diode arrays which contain some diodes which are defective. The defective diodes are compensated in that the respective diodes of the two arrays are aligned in pairs along the scanning direction, with each of the pairs containing at least one good diode. The device also comprises a programmed memory for controlling two switches and for accomplishing a winding or serpentine readout of the arrays. The device is well adapted for landscape scanning.
