Abstract
Several high performing PZT-actuated MEMS laser scanners utilizing mechanical coupling are designed, fabricated, and characterized. Optical angles up to 59.3 deg. and θoptD·fn-products up to 3052 deg.·mm·Hz are demonstrated. These are the highest performing MEMS scanners in the literature. An angle sensor is integrated into one scanner design without any additional processing. The sensor response shows a linear relationship with the mirror rotation. A closed-loop drive was demonstrated using the scanner output.
