This paper presents the design, fabrication and characterization of a novel tip-tilt-piston (TTP) scanning micromirror based on an array of folded piezoelectric unimorph actuators. The micromirror can perform rotational scan around two in-plane orthogonal axes as well as out-of-plane piston motion. The measured resonant frequencies of the fabricated… CONTINUE READING
