摘要： A vibrating element includes a movable part, a substrate made of metal, a driving source, and a holding member holding the substrate. The substrate includes a pair of support beam parts, a support part, and a torsion beam part. Each of the support beam parts has a first end part and a second end part. The support part supports the first end part. The torsion beam part swingably supports the movable part. The second end part of each of the support beam parts is provided with a fixing part fixed to the holding member. By adjusting an inclination with respect to the holding member, the fixing part is fixed to the holding member in a state in which each of the support beam parts applies tension to the torsion beam part in a direction away from the movable part in a first direction in which the torsion beam part extends.

摘要： Provided is a vibrating mirror element including: a mirror part; a substrate made of metal, including a pair of beams, a support supporting each of the pair of beams, and a torsion part swingably supporting the mirror part; a driving source generating a plate wave that swings the mirror part; and a vibration suppression part suppressing vibration transmitted to the pair of beams. The vibration suppression part is configured to suppress the vibration transmitted to the pair of beams by abutting against the pair of beams at a position between a second mirror end among ends of the mirror part that is opposite a first mirror end near the support and the torsion part in a first direction in which the pair of beams extends.

摘要： A light projection method for a moving body which is performed by a processor of the moving body is provided. The method comprises: irradiating light from a light source of the moving body; scanning the light irradiated from the light source with an angle range that is formed by swing a mirror portion of an optical scanner of the moving body; acquiring change information of the angle range at which the mirror portion swings; changing the angle range at which the mirror portion swings based on the acquired change information; and changing an irradiation range of the light irradiated from the light source.

摘要： Provided a reflecting device in which a mirror area is large, wide angle scanning is possible, and a size thereof is reduced, and particularly a downsized reflecting device that has a suitable specification as vehicle-mounted LiDAR. The reflecting device includes an oscillation part, and the oscillation part includes a mirror part supported on a support frame, and a hinge part engaging the mirror part and the support frame. The mirror part oscillates with respect to the support frame, and the hinge part has a tensile strength of 1500 MPa or higher. A mass M of the mirror part and a resonance frequency f0 of the oscillation part satisfy a relational expression (1) below, 0.49*f0+6.23≤M≤68.6*f0+46.8 (1)
