abstract

1D optical micro scanners driven by piezoelectric actuators have designed, simulated, fabricated and tested. The newly designed micro scanners have a structure that rotation bars, hinges and PZT cantilevers support a square mirror (1mm × 1mm). Flat-structured micro scanners have been fabricated from Pt/PZT/Pt/Ti/SiO2 /SOI(Si/SiO2 /Si) multi-layered structure through conventional MEMS micro fabrication technologies. The micro scanner driven at 10 V showed an optical scan angle of 1.5 degree for the static actuation (60 Hz) and of 13 degree for the resonant actuation (4825 Hz), respectively.
