20120033306 | OPTICAL WAVEGUIDE AND DISPLAY DEVICE - In a slab waveguide which expands an image-bearing pupil into a visible image, reflective edge surfaces are used to redirect once-diffracted light back through the same grating structure. The number of separate grating structures thereby can be reduced to two or even one, compared to three in the prior art. | 02-09-2012 |
20120044572 | OPTICAL WAVEGUIDES - An optical waveguide comprising a body of material configured for the contained propagation of light therethrough, a surface relief grating configured to receive the propagating light and at least partially to diffract or reflect it out of the waveguide, and at least one layer of dielectric material of varying thickness having a first surface and a second surface which conforms to a profiled surface of the grating so that the grating exhibits a spatial variation in efficiency dependent on the varying thickness of the dielectric material. | 02-23-2012 |
20120044573 | HEAD MOUNTED DISPLAY - A helmet or head-mounted apparatus has a visor or other curved optical element in front of at least one eye of a wearer, which element also is used as a waveguide. Image-bearing light is injected into the waveguide via an input diffractive element, and propagates through the visor to an output diffractive element which releases the light. The optical powers of the curved waveguide and the input and output diffractive elements are selected so that the released light is delivered as an image to the users eye. | 02-23-2012 |
20120120493 | OPTICAL WAVEGUIDES - The invention relates to a display device for displaying an image over a field of view. The device comprises: an optical arrangement for directing image bearing light from an image source so that the light has rays at a range of angles relative to an injection axis; and an optical waveguide having an input grating for diffracting into the waveguide said light over said range of angles such that all of the diffracted light is totally internally reflected within the waveguide and so that image bearing light output from the waveguide has a field of view corresponding to said range of angles, wherein the input grating is a surface relief grating having a profiled reflective surface and at least one layer of dielectric material conforming to the surface for diffracting light over said range of angles into the waveguide. | 05-17-2012 |
20140362447 | HEAD MOUNTED DISPLAY - A head-mounted or helmet-mounted display apparatus is provided. The apparatus includes an optical element which in use is disposed in front of the eyes of a user. The optical element has a waveguide portion. The apparatus further includes a light source of image-bearing light and two diffraction elements. Each diffraction element is configured for propagation of image-bearing light of the light source through the optical element. Each diffraction element is arranged to release the image bearing light from the optical element. The apparatus further includes a switching element for switching the image-bearing light repeatedly between the first diffraction element and the second diffraction element to provide a first visible image or a second visible image to the respective eye of a user. | 12-11-2014 |
20150062707 | HEAD MOUNTED DISPLAY - A head-mounted or helmet-mounted display apparatus is provided. The apparatus includes an optical element which in use is disposed in front of the eyes of a user. The optical element comprises a waveguide portion. The apparatus further includes a first light source and a second light source of image-bearing light. The apparatus further includes first diffraction element for propagation of image-bearing light of the first light source through the optical element. The apparatus further includes a second diffraction element for propagation of image-bearing light of the second light source through the optical element. The first light source and the second light source is disposed such that relative angular movement of the first light source and the second light source about an axis of symmetry of the optical element adjusts the inter-pupillary spacing of a first visible image and a second visible image presented to a respective eye of a user. | 03-05-2015 |
