Abstract: In an optical scanning apparatus, a light-emitting unit emits light waves. A light-receiving unit receives reflected light of the light waves. A transmissive member transmits the light waves and the reflected light of the light waves. A reflection mirror is arranged further toward the light-emitting unit side and light-receiving unit side than the transmissive member is, includes a reflection surface that rotates, and deflects at least either of the light waves and the reflected light using the reflection surface. The reflection mirror includes a low reflection region on the transmissive member side. The low reflection region has a reflectance of the light waves on the reflection surface that is set to be lower than a reflectance of the light waves on the other region other than the low reflection region, in a state in which the reflection surface is facing the light-emitting unit side or the light-receiving unit side.

Abstract: A road surface displaying device capable of performing a display having high visibility is provided. The road surface displaying device includes a light projecting unit that projects light toward a road surface and performs a display by the light on the road surface, and a polarization controlling unit that sets a ratio of P-polarized light and S-polarized light in the light. The road surface displaying device includes a target position detecting unit that detects a position of a target. The polarization controlling unit sets the ratio according to the position of the target.

Abstract: An optical distance measuring apparatus is provided. The optical distance measuring apparatus includes a housing and multiple light projection and light reception portions. The housing includes an opening face. The multiple light projection and light reception portions emit light, and receive the light after the light is reflected. The multiple light projection and light reception portions are accommodated in the housing. The light is provided by laser light. By combining optical paths of the multiple light projection and light reception portions, a view angle of the optical distance measuring apparatus is widened compared with a view angle of one of the multiple light projection and light reception portions. The optical paths of the multiple light projection and light reception portions overlap with one another in the opening face when seen from a direction perpendicular to a direction along which the view angle of the optical distance measuring apparatus is widened.

Abstract: An aspect of the present disclosure provides an electronic device that includes a housing in which an electronic component is disposed. At least part of the housing is configured by a transmission member that transmits at least one of ultraviolet light, visible light, and infrared light, which have different wavelengths. The housing includes therein a display part that displays information concerning the electronic device. The display part is configured to be able to read the information using any of the light that has been emitted from outside of the housing and has passed through the transmission member, and the transmission member has selective transparency having different transmittances to the light depending on a type of the light.

Abstract: A road surface display device mounted to an own vehicle includes: a road surface image control portion generating a road surface image which is displayed on a road surface ahead of the own vehicle and includes images each indicating an expected arrival zone where the own vehicle is expected to arrive at an expected arrival time; a detection portion obtaining display states of a different vehicle image, which is a road surface image displayed by a different vehicle, and an own vehicle image, which is the road surface image displayed by the own vehicle, and detecting a presence of overlapping or proximity between the two images; and a display adjustment portion, when the presence of overlapping or proximity is detected, displaying an image indicating a shorter expected arrival time in a region where the presence of overlapping or proximity is detected on the road surface.
