Patent number: 11782279Abstract: An example apparatus may include a display, a beamsplitter having a first region and a second region, and a reflective polarizer. The reflectance of the second region of the beamsplitter may be appreciably greater than the reflectance of the first region; for example, at least approximately 20% greater. In some examples, the second region may be a peripheral region surrounding a generally centrally located first region. An example apparatus may be configured so that at least some light emitted by the display is transmitted through the first region of the beamsplitter, reflects from the reflective polarizer, reflects from the second region of the beamsplitter, and is then directed through the reflective polarizer to an eye of a user when the user wears the apparatus. Other devices, methods, systems, and computer-readable media are also disclosed.Type: GrantFiled: March 25, 2022Date of Patent: October 10, 2023Assignee: Meta Platforms Technologies, LLCInventors: Andrew John Ouderkirk, Liliana Ruiz Diaz, Robin Sharma, Hannah Noble

Publication number: 20230017964Abstract: An optical lens assembly to accept various illumination ellipticity profiles as angle of incidence (AOI) varies is provided. The optical lens assembly may include an optical stack, such as pancake optics. The optical lens assembly may also include a switchable optical element communicatively coupled to a controller. The optical lens assembly may further include an optical element, such as a Pancharatnam-Berry phase (PBP) lens, also known as a geometric phase lens (GPL). In some examples, the switchable optical element may be a switchable have wave plate, which may be configured, via application of optical power by the controller, so that the optical lens assembly may accept varying illumination ellipticity profiles as angle of incidence (AOI) increases.Type: ApplicationFiled: July 19, 2021Publication date: January 19, 2023Applicant: Meta Platforms Technologies, LLCInventors: Hannah Noble, Yang Zhao, Chia-Hsuan Tai

Patent number: 10502963Abstract: A method is presented herein for manufacturing an immersed Fresnel structure. A first liquid polymer is applied to a first surface of a substrate, the substrate having a second surface that is opposite the first surface. The first liquid polymer is illuminated with light to change at least one property of the first liquid polymer and obtain a modified polymer attached to the first surface of the substrate. A second liquid polymer is applied to at least a portion of a surface of a Fresnel structure. The second surface of the substrate is applied to an outer surface of the second liquid polymer applied to the Fresnel structure to obtain a stacked Fresnel surface. The stacked Fresnel surface is illuminated with light to obtain an immersed Fresnel structure. The immersed Fresnel structure can be used as part of a near-eye display.Type: GrantFiled: July 16, 2018Date of Patent: December 10, 2019Assignee: Facebook Technologies, LLCInventors: Hannah Noble, Kurt Jenkins
