Barcode Scanners

Barcode scanner is a device used to read the information contained in a barcode. It can be divided into one-dimensional and two-dimensional barcode scanners. The structure of a barcode scanner usually consists of the following parts: light source, receiving device, photoelectric conversion component, decoding circuit, and computer interface. The basic working principle of the scanning gun is: the light emitted by the light source illuminates the bar code symbol through the optical system. The reflected light is imaged on the photoelectric converter through the optical system, and interpreted as a digital signal that the computer can directly accept by the decoder. Except for the classification of one and two-dimensional barcode scanners. It can also be classified as: CCD, full-angle laser and laser handheld barcode scanner.
