Abstract: A head-up display is provided. The head-up display comprises an optical component comprising a surface arranged, during head-up display operation, in a configuration that is conducive to sunlight glare. The head-up display further comprises a reflection suppression device arranged to receive sunlight on an optical path to the surface. The reflection suppression device comprises a lattice structure. The lattice structure extends in a first direction and a second direction. The lattice structure forms a plurality of channels extending in a third direction. Each channel is defined by a respective axis having a first angle in the first direction and second angle in the second direction. The first angle is a function of the first direction.

Abstract: Embodiments include a system having a viewing window and arranged to project a first image on a first plane and a second image on a second plane, the system including (i) a replicator arranged to receive spatially modulated light and form a plurality of replicas by waveguiding between a reflective surface and a transmissive-reflective surface forming an output surface, (ii) a light control device in the optical path of the replicas downstream from the output surface, wherein a first plurality of replicas of the first image form a first light footprint on a first area of the light control device and a second plurality of replicas of the second image form a second light footprint on a second area of the light control device, and (iii) a driver arranged to move the light control device relative to the replicator.

Abstract: A picture generating unit comprises a display device arranged to display a hologram of a picture; and spatially modulate light in accordance with the displayed hologram to form a holographic reconstruction of the picture on a replay plane. The holographic reconstruction comprises a picture area and a non-picture area. The picture generating unit comprises an active mask in or downstream of the replay plane, the mask comprising a propagation area arranged to allow propagation of light along a projection axis, and a non-propagation area arranged to prevent propagation of light parallel to the projection axis. The propagation area and the non-propagation area share a boundary adjustable to change one or more physical parameters of the propagation area. The picture generating unit further comprises a drive means arranged to adjust the boundary to change the one or more physical parameters of the propagation area.

Abstract: A head-up display system includes an eye-box having a first and second dimension, an image projector including a picture generating unit and an optical system, and a movement assembly. The picture generating unit includes a spatial light modulator arranged to spatially modulate light in accordance with a hologram. The optical system relays the spatially modulated light to an optical combiner. The movement assembly moves at least a portion of the image projector rectilinearly between a plurality of positions such that at least one component of the picture generating unit is moved together with the optical system. Spatially modulated light relayed to the optical combiner forms a virtual image viewable from a sub-eye-box having a position in the first dimension being dependent on the position of the at least a portion of the image projector. The eye-box is the sum of the sub-eye-boxes associated with each of the plurality of positions.

Abstract: 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.

Abstract: A method for providing a thin film that is spatially structured on a submicrometric or nanometric scale, formed by a material, on a substrate, so as to obtain a product; the method comprises the steps of: dispersing the material in the substrate in order to obtain a mixture; modeling the mixture to form on a surface of the mixture protrusions and recesses; conditioning the mixture by smoothing any surface roughness thereof; by doing so, the material emerges on the surface only at the protrusions of the mixture.
