SCAN ENGINE WITH BUILT-IN AUTO TRIGGER

摘要

A method and system for scanning objects using a scan engine having two modes are described. Under a first mode, the scan engine generates modulated pulses for determining the existence of symbols such as barcode and a scanning mirror is kept stationary. When it is determined that the symbols exit, the scan engine is switched to a second mode in which continuous light is generated and the scanning mirror oscillates for standard scanning.
