Abstract
An optical imaging system, such as a scanner system for imaging machine-readable indicia may include a lens device, an adapter ring, and a PCB piezoelectric motor. The lens device may include an adjustable optical component operably coupled to a rotatable feature. The adapter ring may be engaged to the rotatable feature of the lens device so as to control movement of the rotatable feature. The PCB piezoelectric motor may include a stator mounted thereto, and a rotor configured to rotate relative to the stator. The rotor may be coupled to the adapter ring so that applying rotational energy to the stator causes the adapter ring to rotate, thereby causing the adjustable optical component to be adjusted.
