Abstract

This paper presents a new type of piezoelectrically actuated scanning micromirror using bulk PZT (lead zirconate titanate) plate and an integrated electromagnetic deflection angle sensor. Proposed actuation mechanism utilizes a commercially available bulk PZT plate attached to a silicon substrate using adhesive. Fabricated device is experimentally characterized and analyzed using finite element analysis. An optical scan angle of 45° at 28.4kHz has been achieved at 50Vpp square wave input. Moreover, a simple deflection angle sensing method using integrated coil and external permanent magnet has been proposed and verified.
