Abstract: A display system for a windshield of a vehicle comprises a projection device configured to generate an image upon a projection surface and a controller for processing information related to the image. Furthermore, the display device is configured with a recording device which is pointed toward the projection surface and connected to the controller by a first data channel. The projection surface is configurable and likewise connected by means of a second data channel to the controller. The projection surface may include a light-transparent liquid crystal display and/or a flexible liquid crystal display, and may be configured as a mirror or as a diffuser for showing the image as a hologram. A method for configuring the display system is also provided.

Abstract: A head-up display device for displaying a virtual image superimposed over a field of view to a viewer is provided. The head-up display device includes a picture generating unit having an illumination source, such as a laser, to generate a real image following a first light beam. A windshield of a vehicle engages the first light beam, either at an inclined angle or perpendicular, to reflect the first light beam away from the viewer as reflected images. A combiner disposed on the windshield including a holographic optical element steers the first light beam toward the viewer as a third light beam to present the virtual image within the field of view of the viewer. Mirrors may direct and magnify first light beam onto the combiner. A method for displaying a virtual image superimposed over a field of view to a viewer using a head-up display device is also provided.

Abstract: A display device for displaying images conveying depth information comprises a first display unit for representing first image information on a first screen. The first display unit comprises the first screen with a holographic optical element, HOE, provided thereon, and a first light source for providing light for illuminating the first screen. The display device further comprises a second display unit for representing second image information. The second display unit comprises a second light source for providing light with a plurality of predetermined discrete wavelengths for creating the second image information, and a second screen which is provided in parallel or oriented at an acute angle relative to the first screen in order to project the second image information onto the first screen and thereby generate a virtual image corresponding to the second image information behind the first screen.

Abstract: A LIDAR system includes a laser projecting a first beam of laser light upon a spatial light modulator, such as a liquid crystal on silicon (LCOS) device, to project a second beam having a pattern of points of relatively high intensity separated from one another by regions of relatively low intensity. A first camera having a first field of view and generates an image signal of the pattern of points of the second beam overlaid upon an image of one or more objects within the first field of view. A picture creation module generates the pattern of points and communicates it to the spatial light modulator. An image processing module detects the position and distance of the one or more objects using the image signal. The picture creation module may generate one of a plurality of different patterns to increase the spatial resolution of the LIDAR system.
