WANDED READING DEVICE AND ITS READING METHOD

摘要

A wand-like reading device for easily reading barcodes of various densities with a wide working angle. The light emitting device, the optical scepter and the related network of the wand reading device of the present invention are so designed as to obtain two data channels in the scanned barcode Respectively. The two channels have different resolutions. Two channels of data are analyzed to obtain one decryption result. Even if the working angle and barcode density change, at least one of the two channels having different resolutions is suitable for detecting all or most of the barcode data. The data of the channel that produces the correct result can be used as is. For example, even if two channels do not produce the correct results themselves, they can analyze each channel's data and combine the right parts of these data to produce one correct decoding result.
