Abstract: A light source system comprising a projection lens, which is capable of producing a far-field image of a light source. The light source comprises a photoluminescent material that when illuminated by light from laser emitters of a first waveband emits light of a second or more wavebands of longer wavelength. The resulting light emission produces a colour perceived as white. The light source is illuminated by a plurality of laser emitters arranged to illuminate the light source in an array-like manner from the front side. Control of the output of one or more of the laser emitters results in a variation of the spatial emission distribution from the light source and hence a variation of the far-field beam spot distribution via non-mechanical means. An optical system is arranged to image light emitted from the photoluminescent material into the far-field, which optical system comprises a converging lens.

Abstract: An illumination system comprises a lightguide (12) having a plurality of light extraction features (LEFs); and a plurality of independently controllable light sources (11a, 11b, 11c). The LEFs have a preferred direction, with light that is incident on an LEF along the preferred direction of the LEF being extracted from the lightguide generally parallel to a reference plane, and light that is incident on an LEF not along the preferred direction of the LEF being extracted from the lightguide at an extraction angle to the reference plane, the extraction angle being related by a response function to an incidence angle between the light propagation direction and the preferred direction of LEF. The shape of the LEFs varies with distance from a reference point or respective reference point so that the response function becomes larger with increasing distance of the LEFs from the reference point.

Abstract: An optical system enables high image quality Head Mounted Displays to be made more compact and/or of reduced weight. The optical system includes at least two or more image panels per eye, two or more reflective surfaces per image panel, and a refractive eyepiece element. Light from each image panel is reflected by a distinct set of optical surfaces before reaching the eye, forming at least two overlapping virtual images per eye. The invention may allow the apparatus to have a compact form factor with weight distribution close to the user's face without compromising on image quality and resolution.

Abstract: A transparent display device includes a screen that has a plurality of light deflecting elements that are separated by transparent areas, and a projector device. The projector device is configured to direct light onto the light deflecting elements and not onto the transparent areas. The display device may include a first screen and a second screen separated longitudinally relative to the projector, wherein each screen respectively has a plurality of light deflecting elements. The projector is configured to direct light onto the light deflecting elements and not onto the transparent areas of the two screens such that light from the first and second light deflecting elements appear in different virtual depth planes. Alternatively, a single screen may have first and second pluralities of light deflecting elements of different optical powers, such that light from the first and second light deflecting elements appear in different virtual depth planes.

Abstract: A backlight unit includes a lightguide, a light source that emits light to the lightguide, and a barrier layer positioned over the lightguide in a light emitting direction relative to the lightguide. The barrier layer defines a bezel area of the backlight unit, and an active area of the backlight unit from which light is emitted from the lightguide is an area adjacent to a boundary of the bezel area. A prism structure is positioned in the bezel area, wherein stray light emitted from the light source uncoupled to the lightguide is at least partially coupled into the lightguide by the prism structure or directed to a greater degree along the lightguide. The prism structure may be configured as a plurality of lenticular triangular prisms, and may be mounted to a mounting frame, back reflector, or flat panel connector of the backlight unit.

Abstract: A head-up-display (HUD) system includes at least one scanning laser projector operative to generate laser light, and a stacked array of multiple-switchable screens arranged relative to the projector to receive laser light generated by the projector, each screen of the stacked array of multiple-switchable screens spaced apart from one another and operative to switch between a transparent state and a diffusive state. A controller is operatively coupled to the stacked array of multiple-switchable screens, the controller configured to time sequentially switch each screen of the array from a transparent state to a diffusive state, wherein only one screen is switched to the diffusive state at any given time. An output of the projector is arranged at an angle or a distance from imaging optics succeeding the array of screens to prevent a specular beam emitted by the at least one scanning laser projector from intercepting the imaging optics succeeding the array of screens when all screens are in the transparent state.

Abstract: A light source system comprising projection optics, which are capable of producing a far-field image of a light source. The light source comprises a fluorescent medium that when illuminated by light from laser emitters of a first waveband emits light of a second or more wavebands of longer wavelength. The resulting light emission produces a colour perceived as white. The light source is illuminated by a plurality of laser emitters arranged to illuminate the light source in an array-like manner. Control of the output of one or more of the laser emitters results in a variation of the spatial emission distribution from the light source and hence a variation of the far-field beam spot distribution. Further, fine variation of the far-field beam spot distribution may be achieved by re-direction of the laser beams by separate control methods.
