Publication number: 20210157152Abstract: An optical device includes a range of angularly selective reflectors are contained within an optical waveguide substrate and substantially optimized according to their reflector order within the sequence of reflectors. This configuration of reflectors ensures that the required angular information is passed through to the correct reflector within the sequence. The angular response in addition reduces or eliminates formation of secondary images carried to successive reflectors, resulting in undesired artefacts.Type: ApplicationFiled: February 4, 2021Publication date: May 27, 2021Applicant: RPX CORPORATIONInventors: James Leighton, Brennon Pennell, Adrian Stannard, Louahab Noui, Nan Ma, Iain Wellington, Philip Greenhalgh, Lawrence Hoar, Iain Wright

Patent number: 10007115Abstract: Fixed position optical devices for displaying augmented reality images are provided herein. In one embodiment an optical device includes a AIIE having a waveguide that reflects a computer generated image along a central viewing axis, the computer generated image being received from an image generator optically coupled to the waveguide, and a fixed lens assembly for coupling a background image with the computer generated image to create the augmented reality display, the fixed lens assembly including a proximal lens disposed on one side of the waveguide, the proximal lens being fixedly spaced apart from the waveguide at a first distance, and a distal lens disposed on an opposing side of the AIIE from the one side, the distal lens being fixedly spaced apart from the waveguide at a second distance.Type: GrantFiled: August 12, 2015Date of Patent: June 26, 2018Assignee: DAQRI, LLCInventors: Philip Greenhalgh, David Crosby, David Hayes
