Abstract: A display system includes: a display element that includes a display surface through which light showing an image is emitted; a concave mirror that reflects the light emitted through the display surface of the display element; and an optical element that includes a wave plate and a transmissive polarizing plate that is a polarizing element, the optical element facing the concave mirror. The concave mirror and the optical element are each provided separately from the display element. The optical element (i) transmits reflected light resulting from the light emitted through the display surface of the display element being reflected by the concave mirror, and (ii) reflects light from outside off a surface of the optical element, the surface facing the concave mirror, the light from the outside entering the optical element from a side through which the reflected light exits, and being reflected by the concave mirror.

Abstract: A display system includes: a display device; a reflection optical system; a housing; and a shield member. The reflection optical system includes at least a last reflective member on which light, emerging from a display screen of the display device, is incident either directly or indirectly. The shield member is held by the housing to assume either a shielding state or an unshielding state. The shielding state is a state where the shield member at least partially cuts off light incident on, or reflected from, the last reflective member. The unshielding state is a state where the shielding state is canceled. The shield member in the shielding state reflects, toward the viewer's eyes, external light impinging on the housing. The housing has a holding structure to hold the shield member, no matter whether the shield member assumes the shielding state or the unshielding state.

Abstract: A biosensor substrate includes a base substrate to which an excitation light beam is entered, a track formed on the base substrate, and a plurality of wells disposed on the base substrate and accommodating a specimen. A region on which the wells are disposed is sectioned into a plurality of zones in a radial direction, and the wells are arranged on the zones in a circumferential direction. The biosensor substrate is driven at a constant angular velocity while a zone is scanned with the excitation light beam. Velocities set to the zones are varied between the zones, and a zone on the outer radial side has a smaller angular velocity.

Abstract: A display system includes: a display device in a mobile body; a concave mirror for displaying, in a first mode, a virtual image of a display image shown by image light emitted by the display device; and a plane mirror for reflecting, in a second mode, a rear-view image shown by light that has entered the mobile body. In a top view of the mobile body, the display device and the concave mirror are disposed such that a straight line connecting centers of the display device and the concave mirror has a predetermined angle relative to a front-and-rear direction of the mobile body. A normal direction at a center of a concave mirror surface of the concave mirror when the first mode is functioning and a normal direction normal to a plane mirror surface of the plane mirror when the second mode is functioning are not parallel.

Abstract: A display device includes: a display element including a display surface on which image is displayed; a first mirror and a second mirror that reflects emission light emitted from the display surface of the display element; and a polarization element. The polarization element is configured to reflect and transmit the emission light from display surface. The emission light from display surface is reflected off polarization element twice and transmitted through polarization element once by a time the emission light is reflected off first mirror and second mirror and exits from display device.

Abstract: A display system includes a display device, a first mirror, and a second mirror. The display device includes a display surface that displays a first image. Light emitted by the display device is incident directly or indirectly on the first mirror. The first mirror reflects the light incident. The light reflected by the first mirror is directly or indirectly incident on the second mirror. The second mirror reflects, toward an eye-box, the light incident. The light reflected by the second mirror enters an eye of an observer present within the eye-box to display, on the eye of the observer, a second image based on the first image. The first mirror is a Fresnel mirror.

Abstract: A display system includes: a display that emits light corresponding to image information; a half mirror that receives the light emitted, reflects, as reflected light, a first component of the light received, and transmits a second component different from the first component; and a first reflecting mirror having a concave surface that receives and reflects the reflected light toward the half mirror. The half mirror includes a first retardation film, a first support substrate, and a reflective polarizing film stacked in this order from a side on which the light emitted is received. The first retardation film changes a phase of the light received. The first support substrate is light-transmissive. The reflective polarizing film reflects a first polarized component and transmits a second polarized component different from the first polarized component.
