摘要： An optical reflection element has a frame-shaped supporting body, a first oscillator and a second oscillator each having a meander shape, and a mirror portion. A line segment connecting a joining position between the mirror portion and the first oscillator to a joining position between the supporting body and the first oscillator, and a line segment connecting a joining position of the mirror portion and the second oscillator to a joining position of the supporting body and the second oscillator cross a mirror portion central axis. An outer circumference of at least any one of turn portions of the first oscillator and the second oscillator is deviated from a first end portion axis that is parallel to the mirror portion central axis and extends along a first side of the mirror portion. Alternatively, an outer circumference of at least any one of the turn portions of the first oscillator and the second oscillator is deviated from a second end portion axis T2 that is parallel to the mirror portion central axis and extends along a second side parallel to the first side of the mirror portion. At least any one of these two conditions is satisfied.

摘要： 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. The first monitor electrode provided on the low-frequency vibrator is connected from the top of the vibrator to an extraction electrode.

摘要： An optical reflection element includes a mirror portion and an oscillator coupled to the mirror portion. The oscillator includes a base, an insulating layer, a drive element, and a monitor element. The insulating layer is formed on the base. The drive element and the monitor element are formed on the insulating layer, and are separated from each other by a separation groove. Each of the drive element and the monitor element includes a lower electrode layer, a piezoelectric layer, and an upper electrode layer formed in that order on the insulating layer. The monitor element has high detection accuracy, allowing the optical reflection element to perform self-excited driving with high accuracy.
