ABSTRACT:
A laser scanning device and a method for operation thereof includes a laser source, and a laser beam deflector assembly. The laser beam deflector assembly includes a motor driven hollow shaft. The rotating hollow shaft includes an optical element at an end portion thereof. The laser source emits a collimated laser beam which passes through the rotating hollow shaft, and is deflected by the rotating optical element mounted within the hollow shaft. The rotating optical element continuously deflects the laser beam and generates a conical-shaped laser beam, which when intercepted produces an inscribed circle. The inscribed circle is collapsed by a scan lens so as to provide uni-directional or multi-directional scan along a desired scan track.
