  • Optical reflection element
    Patent number: 8279508
    Abstract: An optical reflecting element includes a mirror, and a pair of high-frequency vibrators and a pair of low-frequency vibrators for vibrating the mirror. The high-frequency vibrators include a substrate, a bottom electrode layer formed on the substrate, a piezoelectric layer, and a drive electrode and a first monitor electrode as the top electrode layer. One end of the low-frequency vibrator has the substrate shared with the high-frequency vibrator, a bottom electrode layer, a piezoelectric layer, a drive electrode, and a second monitor electrode as the top electrode layer. The other end of the low-frequency vibrator has the substrate shared with the high-frequency vibrator, a bottom electrode layer, a piezoelectric layer, a drive electrode, a first monitor electrode, and an insulator layer as a dead zone for preventing a piezoelectric effect due to the piezoelectric layer from reaching the first monitor electrode.
