CCD / CMOS Barcode Scanners
CCD / CMOS Barcode ScannersCCD (charge-coupled device) or CMOS (Complementary Metal-Oxide-Semiconductor) scanners use a stationary flood of light, usually LEDs (Light Emitting Diodes), to reflect the symbol image back to an array of photosensors, which is extremely small and because there are hundreds of sensors lined up in a row, a voltage pattern identical to the pattern in a barcode is generated in the scanner by sequentially measuring the voltages across each sensor in the row.
