Abstract
A system for correcting the manufacturing errors and variations in the positional alignment and spacing of optical fibers in the scanning head of an automatic digitizing system. A scan head signature is produced by measuring the actual X and Y position for each optical fiber including the variation of each fiber from its nominal X and Y positions. An X correction circuit and a Y correction circuit use the head signature data stored in a signature correction memory to correct the X and Y positions of the stream of scan line data to thereby provide a true video scan of the document data.
