Optical reflection element
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. As one illustrative condition to be satisfied, 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.
