Fabrication and scanning-angle temperature dependence of metal-based, optical resonant scanners with PZT actuation

Metal-based, optical scanning devices with a large mirror size of 1 mm2 and a wide scanning angle of over 90deg were fabricated. A high optical scanning angle (90deg) was achieved at a resonance frequency of 7.33 kHz and a driving voltage of 80 V (peak-to-peak) in ambient air without vacuum packaging. We compared the performance of metal-based, optical… CONTINUE READING
