    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: 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 light deflection element is capable of deflecting incident light so as to follow a position of an observer and suppressing reduction in intensity of light that reaches eyes of the observer regardless of their position. The light deflection element includes: a first optical element configured to deflect incident light; a second optical element configured to change a deflection direction of emitted light by changing a refractive index thereof according to a voltage applied thereto; a third optical element; and a control section configured to control the voltage applied to the second optical element. At least one of interfaces between the first and second optical elements and the second and third optical elements is an aspheric surface. The aspheric surface has an optical power that compensates enlargement of the emitted light which is caused by refractive index distribution caused when a voltage is applied to the second optical element.

    Abstract: The present disclosure provides an image display apparatus having excellent light converging characteristics. The image display apparatus includes: a liquid crystal prism element including a prism array in which a plurality of prisms are arranged, a liquid crystal layer laminated on the prism array, and electrodes provided at position corresponding to the respective prisms which form the prism array; a control section configured to control a voltage to be applied to each electrode; and a position detection section configured to detect a viewing position of a user. The control section is able to apply the same or different voltages to the respective electrodes provided at the positions corresponding to the respective prisms, on the basis of a result of the detection of the viewing position by the position detection section.
