摘要： A method for holographic display calibration using phase modulation includes projecting an initial graphic on a windshield of a vehicle, capturing an image of the initial graphic with a camera inside a vehicle, determining a loss function value between the image of the initial graphic captured by the camera and a target graphic, modulating a phase of a light beam generating the initial graphic using the loss function value to generate an updated graphic, and displaying the updated graphic on the windshield of the vehicle.

摘要： A head-up display apparatus projects a virtual image to be perceived by a user onto a virtual image display part provided in front of the user. The head-up display apparatus includes a display light emitting unit and a display light reflection unit. The display light emitting unit emits display light. The display light reflection unit reflects the display light and emits the reflected display light. The display light reflection unit includes a mirror part having a concave shape and a transmissive-type volume hologram part provided on a surface of the mirror part.

摘要： A vehicle-integrated projector projects an image onto a window of a vehicle including a layer of holographic film. Upon detecting a sensed condition indicative of a possible projection of the image onto a surface beyond the window, projection of the image is adjusted to diminish a visibility of the projection of the image beyond the window independent of headlight actuation.

摘要： A system for calibrating a waveguide-based holographic head-up display that projects images upon a windscreen of a vehicle including a light-diffusing panel positioned at the center of an eyellipse to reflect the images projected by the waveguide-based holographic head-up display. An eyebox of the waveguide-based holographic head-up display is positioned at the center of the eyellipse, and the eyebox is divided into a plurality of unit exit pupils. The system also includes a camera positioned to capture the images reflected by the light-diffusing panel and one or more controllers in electronic communication with the waveguide-based holographic head-up display and the camera. The one or more controllers execute instructions to determine a warp map based on a plurality of corrected individual calibration patterns.

摘要： There is provided ahead-up display in a vehicle arranged to display a picture, the head-up display comprises a first optical sub-system disposed in an upper region of the windscreen and a second optical sub-system disposed underneath the dashboard of the vehicle proximate a lower region of the windscreen. The first optical sub-system is arranged to output a light field. The first optical sub-system comprises a light source and a spatial light modulator. The light source is arranged to emit light. The spatial light modulator is arranged to receive the light from the light source and spatially-modulated the light in accordance with a computer-generated hologram displayed on the spatial light modulator. The second optical sub-system is arranged to receive the light field from the first optical sub-system and project the light field onto a windscreen of the vehicle to form a virtual image on the windscreen.

摘要： A display panel for a vehicle includes a holographic optical element configured to create a real hologram image. A sensor is configured to detect a position of a user's finger with respect to the real hologram image. A display screen is configured to emit light through the holographic optical element. The light from the display screen creates the real hologram image with the holographic optical element being located between the display screen and the real hologram image.

摘要： A display apparatus providing a virtual image to user is provided. The display apparatus may include a hologram optical element on a path of light emitted from a display panel. The display panel may emit light having different peak wavelength ranges. The reflection angle or the refraction angle recorded in the hologram optical element is different according to the peak wavelength range. Thus, the display apparatus may provide a plurality of virtual images having different focal lengths to the user without physical movement or mechanical operation of the display panel.

摘要： A display device includes a light guide plate including a hologram element and a light emitter that emits light to the light guide plate. In addition, the light emitter includes a light source that emits light, and a first optical body including a plurality of first lenses capable of adjusting a contour of the light emitted by the light source. An outline of each of the plurality of first lenses is analogous to a shape of the hologram element.
