    摘要： A volume holographic optical element projection system includes a projection lens, a polarizing beam splitter, a liquid crystal on silicon panel, and a volume holographic optical element. The projection lens includes a light incident side, a light emitting side, and nine lenses. A f-number of the projection lens is in a range from 1 to 3. The f-number is a value derived from dividing the focal length by the entrance pupil diameter. The liquid crystal on silicon panel includes a protection glass. The polarizing beam splitter is located between the light incident side of the projection lens and the protection glass of the liquid crystal on silicon panel. The light emitting side of the projection lens faces the volume holographic optical element.

    摘要： 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. On the process side, the purpose is solved when two virtual images with different wavelengths and/or different polarizations are generated, when a holographic optical element is provided which exhibits different optical properties for different wavelengths and/or different polarizations, and when, in the case of projection of the virtual images while making use of the holographic optical element, the virtual images are represented, due to the different optical properties, at different distances from the driver and/or in different points of view from the driver.

    摘要： An optical combiner includes an off-axis spatially multiplexed lens optically coupled to receive image light and direct the image light in an eye-ward direction. The off-axis spatially multiplexed lens includes a first sub-lens multiplexed with a second sub-lens. The first sub-lens and the sub-lens are configured to direct the image light to designated eyeward-regions.

    摘要： A projection-type display device is connectively coupled to a mobile device (such as a smartphone) where the light generated by a small projection device is directed at a relatively transparent holographic optical element (HOE) to provide a display to an operator of the mobile device or a viewer. The projector and HOE may be configured to produce and magnify a virtual image that is perceived as being displayed at a large distance from the operator who views the image through the HOE. The HOE may comprise a volume grating effective at only the narrow wavelengths of the projection device to maximize transparency while also maximizing the light reflected from the display projector to the eyes of the operator.
