  • Patent number: 12253679
    Abstract: An optical system for an augmented reality (AR) display comprises an image generator for generating image light, and an optical combiner for location in a field of view of a user of the optical system between the user and a scene. The optical combiner is configured to transmit ambient light from the scene towards an eye of the user, the ambient light being incident on a first side of the optical combiner. The image generator and the optical combiner are arranged so that the image light is incident on a second side of the optical combiner, the second side of the combiner being opposite to the first side of the optical combiner.

  • Publication number: 20250060703
    Abstract: In an embodiment a hologram recording system includes an optical system configured to provide first and second beams of electromagnetic radiation, the optical system having a first lens configured to interact with the first beam, a photosensitive recording medium configured to receive the first and second beams and record an interference pattern formed by the first and second beams and an actuation system configured to move a component of the optical system to adjust a position of the first beam relative to the first lens and thereby control an angle of incidence of the first beam at the photosensitive recording medium, wherein the first lens is configured to interact with the second beam, and wherein the actuation system is configured to move a second component of the optical system to adjust a position of the second beam relative to the first lens and thereby control an angle of incidence of the second beam at the photosensitive recording medium.

  • Publication number: 20250020922
    Abstract: The present disclosure provides a waveguide device for generating an eyebox of a display, the waveguide device including: a first volume phase holographic, VPH, grating configured to selectively diffract incident light according to a wavelength and/or an angle of incidence on the first VPH grating to incouple the diffracted incident light into the waveguide device, one or more second VPH gratings configured to selectively diffract the incoupled light according to a wavelength and/or an angle of incidence to direct the incoupled light through the waveguide device; and one or more third VPH gratings configured to selectively diffract the light propagating in the waveguide device according to a wavelength and/or an angle of incidence to outcouple said propagating light, wherein collectively each beam of outcoupled light generates said eyebox.
