Abstract
An electromagnetically actuated optical scanner made using standard printed circuit board technology with integrated dynamic focusing feature is presented. Dynamic focus is achieved with an independently controlled plunger machined on the flame retardant-4 (FR4) platform. Integration of a laser diode and lens, torsional scanner, and the plunger for dynamic focus adjustment on FIN platform greatly improves the form factor of the device for imaging applications. A peak-to-peak mechanical scan angle of 50 degrees is achieved. The dynamic focus control allows for shifting the beam waist location from 80 mm up to 650 mm.
