The PI400M-A4 is suitable for scanning A4 size (216 mm) documents with 15.7 d ots per millimeter resolution. Applications include document scanning, mark rea ders, gaming and office automation equipment. Functional Description The PI400M-A4 imaging array consists of 27 sensors that are cascaded to provide 3456 photo-detectors with their associated multiplex switches, an d a digital shift register that controls its sequential readout. Mounted in the module is on e-to-one graded indexed micro lens array that focuses the scanned documents to image onto its sensing plane.
