One embodiment provides an apparatus for displaying an image comprising: a first optical substrate comprising at least one waveguide layer configured to propagate light in a first direction, wherein the at least one waveguide layer of the first optical substrate comprises at least one grating lamina configured to extract the light from the first substrate along the first direction; and a second optical substrate comprising at least one waveguide layer configured to propagate the light in a second direction, wherein the at least one waveguide layer of the second optical substrate comprises at least one grating lamina configured to extract light from the second substrate along the second direction; wherein the at least one grating lamina of at least one of the first and second optical substrates comprises an SBG in a passive mode.

Transparent waveguide display with grating lamina that both couple and extract modulated light

An optical waveguide comprises at least two TIR surface and contains a grating. Input TIR light with a first angular range along a first propagation direction undergoes at least two diffractions at the grating. Each diffraction directs light into a unique TIR angular range along a second propagation direction.

Transparent waveguide display with passive expander input bragg gratings with different angular diffraction efficiencies

An optical display includes a waveguide comprising an input coupler, first expansion grating, second expansion grating, and output coupler. The input coupler is configured to couple image light from an image source. The first expansion grating is configured to receive the image light, expand the image light along a first axis and away from a first direction at a first angle of expansion, and direct the image light out of the first expansion grating in a second direction different than the first direction. The second expansion grating is configured to receive the image light, to expand the image light along the first axis and towards the first direction at a second angle of expansion, and direct the image light out of the first expansion grating in the second direction.

Dual sided expansion waveguide

An optical display system includes a first display, a plurality of electronic drivers, a controller, and a combiner. Light from a scene is combined with image light from the first display, and the combined light presented to an observer. The combiner includes an electrochromic layer comprising one or more electrochromic regions disposed between the scene and the combiner. The electronic drivers are arranged to electrically connect with and drive respective of the electrochromic regions. The controller is configured to control the plurality of electronic drivers to individually address each of the electrochromic regions to selectively drive some of the electrochromic regions to change light transmission of the selectively driven electrochromic regions.

A system for displaying a stereo image is disclosed. The system includes a stereoscopic head up display (HUD) that includes a combiner and a display configured to display a stereo image. The system further includes either a head tracking sensor or an eye tracking sensor configured to generate a tracking dataset. The system further includes a processor and a memory with instructions that cause the processor to receive the tracking dataset, generate a distortion map based on the tracking dataset and a distortion function, receive a media stereo image, generate a stereo signal based on the distortion map and the media stereo image, and transmit the stereo signal to the display. The system is capable of conveying an image to an operator in the absence of a relay lens.
