ABSTRACT:
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 objects containing symbols such as barcode and a scanning mirror is kept stationary. When it is determined that a triggering event should occur or the symbols exit, the scan engine is switched to a second mode in which light is continuously generated by a light source and used with the scanning mirror oscillating for standard scanning.
