An image display apparatus according to an embodiment of the present technology includes an optical modulator, an optical device, and a sensor unit. The optical device splits a modulated light beam modulated by the optical modulator into a first split light beam and a second split light beam, the first split light beam and the second split light beam each travelling in a different direction, and prevents a light beam, which backwardly travels on an optical path of the first split light beam and enters the optical device, from travelling along an optical path of the second split light beam. The sensor unit is disposed on the optical path of the second split light beam and detects a state of the second split light beam.

Relay systems may be incorporated into optical systems to direct light from at least one image source to a viewing volume. Light from a plurality of image sources may be directed by relay systems to a viewing volume. Some light from the plurality of image sources may be occluded by an occlusion system to reduce undesirable artifacts in when the relayed light from the plurality of image sources are observed in the viewing volume.

A display system for a providing a three-dimensional effect with controlled reflections is disclosed. In one embodiment, the display system includes a display; and a beam splitter positioned between the display and the viewing location. The beam splitter transmits or reflects light based on a characteristic of the light. A physical prop is positioned between the beam splitter and the viewing location. The display is oriented to emit light toward the beam splitter and displays an image at least partially viewable in the viewing location through the beam splitter, such that the image is substantially un-attenuated by the bean splitter. Light reflected from the physical prop and further reflected by the beam splitter toward the viewing location is at least partially viewable in the viewing location. The display system is suitable to enable a substantially full brightness of the image to be viewable in the viewing location.

In an information display apparatus displaying information onto a vehicle, an information display apparatus capable of acquiring a lot of pieces of image information while reducing point-of-view motion of a viewer is provided. An information display apparatus displaying information onto a vehicle includes a first information display apparatus displaying image information of a virtual image by allowing a windshield glass of a vehicle to reflect light, a second information display apparatus acquiring a practical image by scanning the windshield glass with laser light using a MEMS element and a third information display apparatus using an instrument panel of the vehicle.

Lightfield displays for generating a 3D image comprise a 2D array of hogels. Each hogel comprises a 2D array of one or more pixels for generating light rays, and a light distribution control arrangement for controlling in 2D the angular distribution of the light rays from the array which are emitted by the hogel. The 2D array of each hogel is arranged to generate light rays which correspond to an elementary image assigned to the hogel, with each elementary image having a central axis which passes through a center of the image and extends perpendicular to the image. A plurality of the hogels have different lateral offsets between the light distribution control arrangement and the central axis of the respective elementary image.

This application discloses an interaction method performed by a display device and the display device. A three-dimensional virtual object may be obtained; an optical signal of the virtual object is transmitted to a first region of a space and then projected from the first region into a second region of the space through the display device, so that an image of the virtual object is generated in the second region of the space that is outside the display device; when it is detected that a user performs a motion sensing operation on the image of the virtual object in the second region of the space, the virtual object is updated based on the motion sensing operation, to obtain an updated virtual object; and an optical signal of the updated virtual object is then used for generating an image of the updated virtual object in the second region of the space.

An image projection apparatus includes a projection light emission unit, a first optical element, a second optical element, and an optical system. The projection light emission unit has a display surface with a first region and a second region arranged in an x direction. The first optical element reflects first projection light from the first region. The second optical element reflects the first projection light reflected by the first optical element and transmits second projection light from the second region. The optical system projects the first and the second projection light. The first direction corresponds to a direction in which both eyes are aligned when the first projection light and the second projection light are projected into the user's field of view. The display surface includes subpixels constituting one pixel arranged in the first direction and subpixels constituting different pixels in a second direction that intersects the first direction.
