Abstract: The present disclosure provides a virtual image display apparatus, head-up display system, and vehicle that distribute a spatially divided parallax image between a left eye and right eye of a user appropriately. The virtual image display apparatus according to the present disclosure includes a display device configured to spatially divide with a first pitch and to output right-eye images and left-eye images, first optical members periodically disposed with a second pitch, distributing light based on the output from the display device between a right-eye direction and a left-eye direction, and a second optical member configured to reflect or refract, by positive power, the light distributed between the right-eye direction and the left-eye direction by the first optical members. The first pitch is narrower than the second pitch.

Abstract: A projection device includes: a plurality of light sources arranged in a first direction; a spatial modulation element that modulates incident light into image information and emits the image information; a lens that changes an optical path of light emitted from each of the plurality of light sources such that the light emitted from each light source reaches substantially the same region of an incident surface of the spatial modulation element; and a first reflective optical member that deflects the light emitted from the lens toward the spatial modulation element, the first reflective optical member having a shape that reflects light emitted from the lens so as to be incident on an arbitrary point on the incident surface of the spatial modulation element at a predetermined reference incident angle.

Abstract: An imaging apparatus includes: a diffuse-reflector which covers an imaging space on a pathway that a human passes through, from at least a side out of both sides of the pathway, and includes a reflector which diffusely reflects a sub-terahertz wave; a light source which emits a sub-terahertz wave onto the reflector; and a detector which receives a reflected wave of the sub-terahertz wave which has been emitted from the light source, diffusely reflected by the reflector, and reflected by the human, and detects an intensity of the reflected wave received. The diffuse-reflector includes a visible light transmissive area which transmits visible light.

Abstract: An imaging device includes: an area light source including an emission surface from which a sub-terahertz wave is emitted to a measurement target; and a detector including an image sensor that receives a reflected wave generated by the measurement target reflecting the sub-terahertz wave emitted from the emission surface. The area light source includes: at least one point light source that emits a sub-terahertz wave; and a reflector that reflects the sub-terahertz wave emitted from the at least one point light source, to generate a sub-terahertz wave to be emitted from the emission surface. The reflector has a reflection surface that is a bumpy surface which includes two or more frequency components in a spatial frequency range and whose roughness curve element mean length RSm is at least 0.3 mm.
