Abstract: An imaging apparatus captures an image of a person passing through a predetermined space, using a sub-terahertz wave. The imaging apparatus includes an emitter that emits the sub-terahertz wave to the person, and a detection device. The detection device includes: an optical system that images a reflected wave which is the sub-terahertz wave emitted from the emitter and reflected by the person; and a plurality of pixels that are disposed in a planar arrangement and each receive the reflected wave imaged by the optical system, and generates an image based on cumulative intensities, each being obtained by accumulating an intensity of the reflected wave received by each of the plurality of pixels for a predetermined time, and the planar arrangement of the plurality of pixels. The predetermined time is λ/1778 seconds or longer, when the wavelength of the sub-terahertz wave is taken as λ mm.

Abstract: A display device includes a display panel , a plurality of light sources arranged in a first direction orthogonal to a normal direction of the display panel, a light guide panel on which light from a plurality of light sources is incident and including an emission surface that emits light toward the display panel, and a first optical member disposed between the display panel and the light guide panel and including a first surface opposing the emission surface of the light guide panel, a second surface provided opposite to the first surface to oppose the display panel, a Fresnel lens provided on the first surface, and an optical array provided on the second surface. As viewed in at least one of the first direction and a second direction orthogonal to both the normal direction and the first direction, the Fresnel lens emits light passing through a center of the display panel .

Abstract: The present disclosure provides an image display that includes a light source unit, a display panel that displays image, and a light guide panel that guides light emitted from the light source unit to the display panel. The light guide panel has an incident surface facing the light source unit, an output surface facing the display panel, and a bottom surface facing the output surface on a side opposite to the display panel. The incident surface is a side surface of the light guide panel located between the output surface and the bottom surface. The incident surface has a concave portion in which a part of the incident surface is recessed from remaining portions when viewed from a direction perpendicular to a light guide direction of light in the incident surface and an emission direction of light in the output surface.

Abstract: An imaging apparatus includes an emitter that emits a sub-terahertz wave to a person, a detection device, and a phase modulator. The detection device includes: an optical system that images a reflected wave which is the sub-terahertz wave emitted from the emitter and reflected by the person; and a plurality of pixels that are disposed in a planar arrangement and each receive the reflected wave imaged by the optical system, and generates an image, based on the reflected wave received by each of the plurality of pixels. The phase modulator changes an angular distribution of a phase of the reflected wave to be received by the plurality of pixels in the detection device during an exposure period in which the detection device generates the image.

Abstract: A display device includes a display panel and a lighting device. The lighting device includes a light source, a light guide panel including an emission surface from which a light of the light source is emitted toward the display panel, a first optical member including a prism array opposing the emission surface of the light guide panel, and a second optical member provided with a Fresnel lens on a surface opposing the emission surface of the first optical member, As viewed in a first direction orthogonal to a normal direction of the display panel, the Fresnel lens emit a light passing through a center of a transmissive region of the display panel in a direction inclined at a fifth angle with respect to the normal direction and bigger that a fourth angle between the display panel and the emission surface of the light guide panel.
