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.

Abstract: A display panel according to the present disclosure is a display panel with which an optical pen can be used. The display panel includes: a position information pattern layer which causes the optical pen to identify a position on the display panel; a color filter layer including a color filter partitioned by a lattice structure; and a non-visible light reflection layer having a shape which diffuses and reflects a part of a non-visible light emitted from the optical pen. The non-visible light reflection layer is disposed between the position information pattern layer and the color filter layer, and an amount of light which is reflected by the non-visible light reflection layer and then enters the optical pen is larger than an amount of light which enters the optical pen through the non-visible light reflection layer after being transmitted through the color filter layer and then reflected.
