Decoded Scan Engine
- The scan engine emits a beam of laser light that reflects off the
bar code to be decoded. Black bars absorb light, white spaces reflect light. The scan engine
collects the reflected light and processes the signal through several analog filters. The
filtered signal is digitized into a Digitized Barcode Pattern (DBP). Timing information is
analyzed by the decoder micro-controller to decode and transmit the data contained in the
bar code. Data transmission is carried out using Symbol's proprietary SSI Interface.
