    摘要： There is provided a head-up display having an eye-box comprising a driver monitoring system, picture generating unit and optical system. The driver monitoring system is arranged to illuminate and monitor a driver. The driver monitoring system comprises a first display channel. The picture generating unit is arranged to display a picture on a replay plane. The picture generating unit comprises a second display channel Each display channel comprises a light source, spatial light modulator and controller. Each light source is arranged to emit light. Each spatial light modulator is arranged to receive light from the respective light source and output spatially-modulated light in accordance with a computer-generated hologram displayed on the spatial light modulator to form a respective light pattern on the replay plane. Each controller is arranged to output the computer-generated hologram to the spatial light modulator. The optical system is arranged to relay each light pattern from the replay plane. The optical system comprises an input, output and at least one mirror. The input is arranged to receive light of each light pattern. The output is arranged to output light of each light pattern. The at least one mirror is arranged to guide light from the input to the output along an optical path. The light pattern formed by the first display channel is an infrared light pattern. Each light pattern is a holographic reconstruction.

    摘要： There is provided a head-up display for a vehicle. The head-up display has a first housing and a second housing. The first housing comprises a picture generating unit and optical system. The second housing comprises a substantially flat cover glass and a layer. The picture generating unit is arranged to output pictures. The picture generating unit 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-modulate the light in accordance with computer-generated light-modulation patterns displayed on the spatial light modulator to form a holographic reconstruction corresponding to each picture. The optical system is arranged to receive the pictures output by the picture generating unit and relay the pictures using an optical combiner to form a virtual image of each picture. The optical combiner combines light output by the picture generating unit with light from a real-world scene to present combined images to a viewer within an eye-box. The second housing is disposed between the first housing and optical combiner. The substantially flat cover glass is arranged to protect the first housing. The layer is arranged to change the trajectory of light such that any sunlight reflected by the cover glass is deflected away from the eye-box.

    摘要： There is provided a head-up display for a vehicle having a window. The head-up display comprises a picture generating unit (410) and an optical system (420). The picture generating unit is arranged to output pictures. The optical system is arranged to receive the pictures output by the picture generating unit and project the pictures onto the window (430) of the vehicle to form a virtual image (450, 707) of each picture within a virtual image area (605). The picture generating unit is arranged to output pictures within a cropped picture area such that the virtual image area (605) has a corresponding cropped shape. FIG. 7 illustrates a perspective view of a three lanes road (501,502,503) onto which a virtual image (707) within a cropped virtual image area (605) is overlaid.

    摘要： A head-up display arranged to form a virtual image viewable from an eye-box area. The head-up display is arranged to received picture content within a sub-region of a substantially quadrilateral display area. The head-up display further comprises an optical relay system arranged to relay the received picture content to an eye-box of the head-up display such that a virtual image of the picture content is visible therefrom. The optical relay system comprises at least one optical component shaped in correspondence with the shape of the sub-region. The shape of the eye-box area is non-rectangular such as a corner-cropped rectangular shape or elliptical shape.

    摘要： A light detection and ranging system arranged to scan a scene comprises a light source arranged to output light having a first characteristic. A spatial light modulator is arranged to receive the light from the light source and output spatially-modulated light in accordance with computer-generated holograms represented thereon. A holographic controller is arranged to output a plurality of holograms to the spatial light modulator. Each hologram is arranged to form a corresponding light footprint within the scene. The holographic controller is further arranged to change the position of the light footprint within the scene. A light detector is arranged to receive light having the first characteristic from the scene and output a light response signal. The plurality of computer-generated holograms comprise a first plurality of holograms arranged to provide a first scan and a second plurality of holograms arranged to provide a second scan. In embodiments, the first plurality of holograms and second plurality of holograms are interleaved.

    摘要： There is disclosed herein a waveguide comprising an optical slab and an optical wedge. The optical slab has a first refractive index, n1>1. The optical slab comprises: a pair of opposing surfaces and an input port. The pair of opposing surfaces are arranged in a parallel configuration. The input port is arranged to receive light into the optical slab at an angle such that the light is guided between the first and second opposing surfaces by a series of internal reflections. The optical wedge has a second refractive index, n2, wherein 1
