摘要:
This transparent element (10) comprises: two outer layers (2, 4), each of which has a smooth outer surface (2A, 4A) and which consist of dielectric materials having substantially the same refractive index (n2, n4), and a central layer (3) inserted between the outer layers, formed either from a single layer made from a metal material or from a dielectric material having a refractive index different to that of the outer layers, or from a stack of layers that comprises at least one layer made from a metal material or from a dielectric material having a refractive index different to that of the outer layers. All the contact surfaces (S 0 , S1) between two layers of different natures or having different refractive indices are textured and parallel to each other, the ratio of the total reflection (R utile ) of the element (10) on the side of a first outer layer (2) in a given wavelength region to the total reflection (R parasite ) of the element (10) on the side of the second outer layer (4) in said given wavelength region being greater than or equal to 1.5.

A glare visor (13) for reducing ambient light intensity perceived by a wearer viewing a head-up display (3) employing display light (7) including a given wavelength(s) of light. The visor includes a visor body comprising optically transparent material which is partially absorbing of light of visible optical wavelengths thereby to reduce the intensity of ambient light transmitted therethrough to the wearer. A transparent optical coating (12) is formed upon a surface of the visor body which is partially transmissive of light of visible optical wavelengths amongst which it is preferentially transmissive of light of a sub-range of wavelengths for including therein the wavelength(s) of display light. This permits a perceived enhancement of contrast between display light (7) relative to ambient light (8).
摘要:
A wire grid polarizer (10, 20, 30, 40, 50, 60, 70, 80, 90, 100) comprising an array of parallel, elongated first rib groups (14) disposed over a substrate (11). Each first rib group can comprise a central first transmissive rib (12) and a pair of first wires (13) including a first wire disposed along each side of the first transmissive rib. A first dielectric material (16) can substantially fill first gaps between each rib group and an adjacent rib group. An array of parallel, elongated second wires (15) can be disposed over the rib groups and the first dielectric material. The first wires or the second wires can be absorptive and the other of the first wires or the second wires can be reflective.
