Abstract: The Disclosure concerns a laser projection arrangement and a process for the generation of virtual images, the purpose of which is to present a solution which allows a representation of multiple virtual images in different distances or planes and different points of view and that can be manufactured economically. On the arrangement side, this purpose is solved when one of at least two picture generating units that generate virtual images that differ in their wavelength and/or their polarization is arranged and when a holographic optical element is arranged on or in the projection surface.

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 multi-image head-up display device for displaying a plurality of virtual images at different projection distances from a driver of a vehicle includes a picture generating unit with an illumination source that may include a plurality of lasers of different colors to illuminate a spatial light modulator with a first light beam. The spatial light modulator includes blocks of modulating elements to diffract the first light beam to form first and second real images upon first and second respective projection surfaces, each spaced apart from the spatial light modulator by a different focal length. The blocks may be configured as Fourier and/or Fresnel diffractive optical elements. A projection assembly may magnify and direct the real images to the viewer as virtual images each having a different projection distance from the viewer. A method for generating a plurality of virtual images with a head-up display device is also provided.

Abstract: Disclosed herein are devices, methods and systems for producing hologram-based indicia for a vehicle dashboard/cockpit. By employing the aspects disclosed herein, indicia (electronically coupled to the vehicle's microprocessor), is lighted and projected in a three-dimensional virtual manner. The aspects disclosed herein may be embedded in various portions in the vehicle and thus, not consume extra space or area required to create virtual images through other techniques.

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 includes at least three light sources, each one arranged to emit light with a basic color different from the basic color of the other light sources, a digital micro mirror device including an array of micro mirrors, wherein the light of the light sources is directed onto the digital micro mirror device, at least one combiner for displaying an image, and at least one control unit for multiplexing the light sources so as to sequentially emit light thus creating a field sequential color system and for controlling the digital micro mirror device so as to selectively rotate the micro mirrors between an on state, where the light from the light sources is reflected into an optical path towards the combiner, and an off state, where the light is reflected away from that optical path. A method for operating the head-up display is also disclosed.
