Abstract: A light detecting device includes a reception optical system that guides a reflected beam along a reception optical axis and a light receiver that outputs a detection signal by receiving the reflected beam. The light receiver forms a reception surface having a reception aspect ratio in which a long side extends along a first reference axis orthogonal to the reception optical axis. The reception surface is inclined around the first reference axis with respect to a second reference axis orthogonal to the reception optical axis and the first reference axis.

Abstract: A LIDAR device includes a light source, a mirror, a rotatable shaft, and a motor. The light source configured to emit a light beam having a predetermined light beam width for scanning a scanning zone. The rotatable shaft has a center axis parallel to a reflective surface of the mirror and is connected to a back surface of the mirror. The motor is configured to rotate the shaft to cause the mirror to swing between a first position and a second position. The light source and the mirror are arranged to have a positional relationship such that a mirror center is aligned with the light beam center when the mirror is at the first position, and the mirror center shifts within a motion area when the mirror is swinging between the first position, non-inclusive, and the second position, inclusive.

Abstract: In a head-up display, a cover member includes a first transmissive member and a second transmissive member that transmit a light beam including an image generated by an image generation unit. The first transmissive member is formed to face upward from a front end to a rear end. Likewise, the second transmissive member is formed to face upward from a front end to a rear end. The rear end of the first transmissive member is offset to an upper side from the front end of the second transmissive member.

Abstract: A light diffusion member constituting a head-up display device includes multiple micro-lenses and has a curved base surface. The edge angle is larger than the base surface angle change amount. The edge angle is an angle formed by one of tangent lines of two micro-lenses and the other of the tangent lines passing through a boundary between two adjacent micro-lenses on a cross section orthogonal to the base surface. A reference line has a constant direction on the cross section, and a normal line passes at an arbitrary position on the base surface. The maximum value is θmax and the minimum value is θmin among angles between the normal line and the reference line. The base surface angle change amount is the absolute value of the difference between θmax and θmin.

Abstract: A scanning unit scans laser light emitted from a laser light emitting unit. A condensing lens condenses the laser light scanned with the scanning unit and forms a beam. A screen forms the display image thereon upon incidence of the beam formed with the condensing unit. A projection unit projects the display image formed on the screen onto the display member. The screen includes a micromirror array or a microlens array. When the beam is incident on any point of the micromirror array or the microlens array, two or more components forming the micromirror array or the microlens array overlap with a spot of the beam. When a center of the beam and a center of any component among the components are matched, a center of a neighboring component next to the component of interest is outside the spot of the beam.

Abstract: An optical sensing device includes an optical unit and an accommodating unit. The accommodation unit includes an optical window portion which transmits the projected beam from the accommodation chamber to the detection area and transmits the reflected beam from the detection area to the accommodation chamber. The accommodation unit includes a holding portion which holds the optical window portion from a side of an outer periphery. The accommodation unit further includes an optical partition member which is arranged to partition between the optical unit and the optical window portion.

Abstract: A laser radar device includes: a light source; a mirror rotatable about a rotation shaft to reflect laser light emitted by the light source; a window; and a detector to detect laser light. The mirror has a low reflection area having a lower reflectance than the other region of the mirror, in a state where a mirror surface faces toward the light source, at position adjacent to the light source than the detector in an axial direction of the rotation shaft and adjacent to the window than a region where the laser light emitted by the light source hits for a first time in a radial direction of the rotation shaft. The window has an inclined posture in which a distance from the rotation shaft is shorter at position adjacent to the detector than at position adjacent to the light source.

Abstract: A virtual image display device displays a virtual image by projecting a display light of an image toward a projection unit, and includes: a display unit configured to emit the display light; and a diffraction reflection element configured to reflect the display light emitted from the display unit by diffraction. The diffraction reflection element has a plate shape along a horizontal plane. The diffraction reflection element is configured to emit the display light toward the projection unit arranged above the diffraction reflection element when the display light is incident, and is set such that an angle of incidence on the diffraction reflection element is larger than an angle of emission from the diffraction reflection element.

Abstract: A laser projection portion projects multiple laser light fluxes having different wavelengths and superimposed one on another. A scan portion scans the laser light fluxes from the laser projection portion. The image is drawn on a screen member upon incidence of the laser light fluxes scanned by the scan portion. A refraction element portion having positive refractive power is located on a light path between the scan portion and the screen member and adjusts an incident angle of the laser light fluxes to the screen member by refraction. The refraction element portion includes a positive lens part and a negative lens part. The positive lens part has positive refractive power. The negative lens part is made of a medium with a higher dispersing quality than a medium forming the positive lens part and has negative refractive power.
