    Abstract: A mirror driving mechanism includes a plate-shaped base portion, a mirror that is installed at the base portion, and a temperature detecting section that is installed at the base portion and that detects a temperature of the base portion. The base portion includes a thin portion that is disposed away from an outer edge of the base portion and that has a through hole extending through the base portion in a plate-thickness direction of the base portion, a thick portion that is connected to the thin portion, that is thicker than the thin portion in the plate-thickness direction of the base portion, and that extends along the outer edge so as to surround the thin portion, and a first shaft portion extends into the through hole from an outer periphery of the through hole.

    Abstract: An optical module includes a light-forming part and a protective member. The light-forming part includes a base member, a semiconductor light-emitting device, a lens, and a light-receiving device mounted on the base member and disposed, in the emission direction of the semiconductor light-emitting device, between the semiconductor light-emitting device and the lens. The light-receiving surface of the light-receiving device inclines toward the emission portion of the semiconductor light-emitting device such that an inclination angle θ is more than 0° and 90° or less, the inclination angle θ being an angle formed between the optical axis of the semiconductor light-emitting device and a plane including the light-receiving surface of the light-receiving device.

    Abstract: An optical module includes a light-forming unit configured to form light, and a protective member surrounding and sealing the light-forming unit. The light-forming unit includes a laser diode, a first MEMS including a first mirror having a first reflective surface that reflects and scans light from the laser diode, the first mirror oscillating to form a first plane, and a second MEMS including a second mirror having a second reflective surface that reflects and scans light from the first mirror, the second mirror oscillating to form a second plane orthogonal to the first plane.

    Abstract: An optical module includes a first semiconductor light-emitting element, a second semiconductor light-emitting element, a first lens, a second lens, a filter that multiplexes the first light and the second light, a base plate that has a first surface on which the first semiconductor light-emitting element, the second semiconductor light-emitting element, the first lens, the second lens, and the filter are mounted and a second surface opposite the first surface in a thickness direction, and a support base that is in contact with a part of the second surface and that supports the base plate. The base plate has a filter mounting region in which the filter is mounted. The optical module has a gap between a region of the second surface corresponding to the filter mounting region and the support base.
