Abstract: An optical distance measuring device includes: a light source unit that irradiates a measurement region with irradiation light; a light receiving unit that has a light receiving surface including a plurality of light receiving elements capable of receiving reflected light from a range including the measurement region corresponding to irradiation with the irradiation light and outputs a signal corresponding to a light receiving state of the reflected light for each of the light receiving elements; and a measurement unit that measures a distance to an object in the measurement region by using the signal outputted from the light receiving unit. The light receiving unit has a function of selecting a light receiving element that outputs the signal so that a light receiving position at which the reflected light is received is variable, and the light receiving unit changes the light receiving position to a plurality of positions with respect to a position of the reflected light.

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: An optical detection apparatus is provided. The optical detection apparatus includes a light emitting unit, a light receiving unit, a storage unit, and a determining unit. The light emitting unit includes a plurality of light-emitting elements. The light receiving unit includes a light-receiving element arrayformed by a plurality of light-receiving pixels, which receive reflected light corresponding to emitted light of the light emitting unit. The storage unit stores a reference light-receiving region on the light-receiving element array corresponding to a location of occurrence of light intensity unevenness included in the emitted light of the light emitting unit. The determining unit determines an optical axis misalignment using a positional displacement between the reference light-receiving region and a detected light-receiving region of light intensity unevenness included in the reflected light of the emitted light on the light-receiving element array.

Abstract: An image capturing apparatus includes an optical system and an image sensor to capture images of a close object and distant object. The optical system includes a convex lens as a first optical member and a glass plate as a second optical member with a refractive index higher than that of air. The second optical member is located in between the first optical member and a first image point at which a real image of the close object is formed, to absorb a positional difference between the first image point and a second image point at which a real image of the distant object is formed. The image sensor includes multiple light reception elements to generate a single picture frame that contains simultaneously a real image of the close object and a real image of the distant object.
