Abstract: A display control system 100 includes: a display panel 220 that includes a pair of polarizing plates 250; a pattern layer 230 has formed therein a plurality of patterns 260; a light source 140 that emits light to be absorbed by the patterns 260; a reflector 240; an identification device 160 that reads the pattern 260 from the light which is emitted from the light source 140, is reflected on the reflector 240, and then passes through the display panel 220 and the pattern layer 230, and identifies a position, on the display surface, of the pattern 260; and a display controller 130 that controls display information in accordance with the position identified by the identification device 160. A transmittance of the pair of polarizing plates 250 at a peak wavelength of the light emitted from the light source 140 is not lower than 70%.

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: An imaging apparatus includes: a reflector which covers an imaging space on a pathway that a human passes through, from at least one of both sides of the pathway, and diffusely reflects a sub-terahertz wave; a first light source which emits a sub-terahertz wave onto the reflector; and a first detector which receives a reflected wave of the sub-terahertz wave emitted from the first light source, diffusely reflected by the reflector, and reflected by the human, and generates an image based on the reflected wave received. The first light source and the first detector are located at a first direction side relative to a center of the imaging space in a direction in which the pathway extends.
