Abstract: A laser scanning device includes: a plurality of laser light sources, each of the plurality of laser light sources emitting a laser light having a light intensity distribution having an elliptical shape; an aperture through which the laser lights emitted from the plurality of laser light sources pass; and a scanning mirror for reflecting the laser lights from the aperture to a scan position. A position of the aperture is adjustable in a first adjustment direction. The plurality of laser light sources are oriented so that long axis directions of the light intensity distributions of the laser lights emitted by the plurality of laser light sources are parallel to the first adjustment direction at positions at which the laser lights emitted by the plurality of laser light sources enter the aperture.

Abstract: An image projection apparatus (1) joins a plurality of display images displayed by scanning a plurality of light beams, as if there is no seam between them, thereby displaying a large-sized high-quality image. The image projection apparatus (1) includes a MEMS mirror device (11), a MEMS mirror control unit (13), and a laser beam detector (19). The MEMS mirror control unit (13) makes the laser beam detector (19) irradiated with a first light beam (L1), and at this time adjusts a position of a first display image (18a) on the basis of a difference between a detection signal output from a first light sensor (191) and a detection signal output from a second light sensor (192); the MEMS mirror control unit (13) makes a first light reception surface and a second light reception surface irradiated with a second light beam (L2), and at this time adjusts a position of a second display image (18b) on the basis of a difference between a detection signal output from the first light sensor (191) and a detection signal output from the second light sensor (192).

Abstract: An optical scanning device includes a first scanning driving unit and a second scanning driving unit. The first scanning driving unit includes a scanning mirror and a frame structure supporting the scanning mirror. The first scanning driving unit is configured to cause the scanning mirror to rotate about a first rotation axis by means of deformation of the frame structure. The second scanning driving unit includes a rotation holder supporting the first scanning driving unit and a supporting shaft. The second scanning driving unit is configured to cause the rotation holder to rotate about the second rotation axis. The frame structure includes a pair of beams provided so as to sandwich the scanning mirror in a direction of the first rotation axis, and a pair of base portions provided on sides of respective beams of the pair of beams opposite to the scanning mirror. Each of the pair of base portions has an elongated shape elongated in a direction of the second rotation axis, and is deformable.
