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: The present disclosure provides a non-visible light reflective sheet including a base material having a corrugated surface on a reference surface, and a reflective layer formed along the corrugated surface and reflecting non-visible light. As for the non-visible light reflective sheet, when an angle of a tangent of the corrugated surface being inclined with respect to the reference surface is an inclination angle, a distribution rate of the inclination angle of 25 deg is 1.0[%/deg] or more, and a proportion of a projected area, onto the reference surface, of a region where the inclination angle is 40 deg or more to a total area of the reference surface is 20% or less. Thus, the non-visible light reflective sheet having a further excellent reflection characteristic can be provided.

The first transparent substrate has an uneven shape on one surface of the first transparent substrate. The semitransparent reflective layer is provided on the surface of the uneven shape and configured to reflect a part of light and transmit the remaining light. One of the first transparent substrate and the second transparent substrate disposed closer to a projection side than the semitransparent reflective layer is made of a material exhibiting birefringence of less than or equal to 500 nm.

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.

Abstract: The display device includes: a display panel; and a surface light source section. A transmittance of light transmitted from a front surface of a prism sheet of the surface light source section is lowest when an incident angle thereof is a determined angle. An angle distribution conversion sheet of the surface light source section has a conversion region that causes light incident on a front surface thereof at the determined incident angle to be emitted from a back surface thereof at an emission angle of not larger than 40° or not smaller than 60°, in a cross-sectional view in a direction perpendicular to an extension direction of prisms. When light is applied to the front surface of the angle distribution conversion sheet at the determined incident angle and in the direction in a front view, 20% or more of the light passes through the conversion region.
