摘要:
An autostereoscopic display configured to display a three dimensional (3D) image of a scene. The autostereoscopic display uses a single projector to project a plurality of projected images into a mirror arrangement fixedly positioned in the projection field of the single projector to reflect the plurality of projected images onto the holographic diffuser from distinct directions such that a 3D image is perceived by a person viewing the holographic diffuser.

A windshield display system that includes a light source such as a laser configured to project light from a plurality of source locations onto a desired location of a windshield. The number of source locations and relative spacing apart of the source locations is such that light emitted from the source locations and reflected into an eye of an operator is characterized as having a reflected light power less than a reflected power threshold.
摘要:
A windshield display system and method of operating the same configured to detect an obstruction of light projected by the system. A light source emits a light beam that reflects off a scanning mirror to direct the light beam to a desired on a windshield. The system includes a light detector configured to detect emitted light generated in response to the light beam illuminating the desired location. The system is arranged so the light beam and the emitted light that is detected travel essentially the same light path between the scanning mirror and the windshield. As such, an obstruction of the light path is readily detected based only on the intensity of the emitted light detected by the light detector.
摘要:
A volumetric display that includes a dispersion block defining a plurality of voxels that are characterized as being visibly apparent when illuminated by impinging light, a projector configured to project one or more light rays for illuminating one or more of the plurality of voxels, and a plurality of arrays of electrowetting mirrors arranged about the dispersion block, wherein each electrowetting mirror is operable to reflect a light ray from the projector toward a selected voxel. The arrays of electrowetting minors provide for a volumetric display that is readily focused.

A heads-up display system is configured for use in a vehicle. The system includes a standard vehicle window (i.e. no special coatings), an image projector, and a vehicle dashboard equipped with a faceted reflective surface. The image projector is configured to project an image onto the faceted reflective surface. The faceted reflective surface is configured to reflect the image from the image projector onto a window surface of the standard vehicle window. The window surface is oriented to reflect the image from the faceted reflective surface toward an occupant. The faceted reflective surface may be disposed within a plurality of troughs separated by a plurality of diffuse reflecting partitions. The plurality of troughs may be configured to shield the occupant from extraneous reflections. The faceted reflective surface may include a plurality of electrically controlled facets. The plurality of electrically controlled reflective facets may be an array of electrowetting cells.

A system, controller, and method for controlling a light distribution pattern. A light source and an electrowetting lens cooperate to vary a light distribution pattern of light from the light source. An object detector is used by a controller determine the location of an object and operate the electrowetting lens in order to control the light distribution pattern based on the location of the object. The electrowetting lens provides for faster redirecting of light toward an object when compared to mechanical based system. The light source may be an array of light emitting diodes to provide a reliable, energy efficient source of light.

A vehicle front lighting assembly, or headlight assembly, that includes one or more variable tint electrowetting elements overlying a portion of the assembly lens surface. The variable tint electrowetting element is configured to operate to a transparent state whereby the hue of light passing therethrough is not changed, and a tinted state where the hue of light passing therethrough is changed. Alternatively, the variable tint electrowetting element is configured to operate to the tinted state and an opaque state where light is blocked from passing through the electrowetting element. The assembly may use light emitting diodes (LED) as an alternative to more conventional light sources.
摘要:
A dual view or two-sided display system to display two different images in substantially opposite direction using a single transparent display to time-multiplex the images and two shutter devices to alternately block each side from being viewed according to the image being displayed. The system includes reflective devices between each side of the transparent display and the two shutter devices so light can be reflected from one side of the transparent display to the other side of the transparent display in order to supplement the light intensity of the image being displayed.
