Abstract: An optical module includes a light-forming unit to form light. The light-forming unit includes a base member having an electronic temperature control module, a base plate, a plurality of submounts, and a microelectromechanical system (MEMS) base. The light-forming unit also includes a plurality of laser diodes arranged on the submounts, a filter arranged on the base plate and located to receive the light emitted from the plurality of laser diodes and multiplex the emitted light, a MEMS arranged on the MEMS base and located to receive the light multiplexed by the filter. The MEMS includes a scanning mirror to scan the light multiplexed by the filter, and the electronic temperature control module regulates a temperature range of the MEMS. The light-forming unit also includes a protective member surrounding and sealing the light-forming unit, which includes a base body and a lid welded to the base body.

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: 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.
