Patent number: 11422505Abstract: The apertures typically used for hologram recording create unwanted secondary holograms by diffracting light. Aperture-free hologram recording eliminates these unwanted secondary holograms. Aperture-free hologram recording includes applying a mask to the holographic recording medium. The mask controls the size of the recorded hologram like an aperture but does not create unwanted secondary holograms. Hologram fringes are only present in the desired recording area and a thin boundary region. The mask may be present during recording, or the mask may be used to pre-bleach the holographic recording medium. Pre-bleaching the holographic recording medium renders a portion of the holographic recording medium insensitive to light, the hologram is recorded in the light-sensitive portions of the holographic recording medium.Type: GrantFiled: November 29, 2018Date of Patent: August 23, 2022Assignee: Google LLCInventor: John Cormier

Patent number: 11307413Abstract: Systems, devices, and methods for eyebox expansion in wearable heads-up display are described. The eyebox of a wearable heads-up display may be expanded by increasing the bandwidth of the hologram comprising the holographic combiner of the wearable heads-up display. The bandwidth of the hologram may be increased by physically coupling a donor film to a hologram film, causing donor material to diffuse into the hologram film and then fixing the donor material in place. Diffusion of donor material into the hologram film causes a change in the slant angle and/or the spacing of at least a portion of the hologram fringes of the hologram film, broadening the bandwidth of the hologram.Type: GrantFiled: March 1, 2019Date of Patent: April 19, 2022Assignee: Google LLCInventors: John Cormier, Laleh Mokhtarpour, Sylwia Agnieszka Lyda, I-Hsiang Albert Chen

Publication number: 20190271944Abstract: Systems, devices, and methods for controlled hologram playback shifting are described. The playback of a hologram may be shifted to a longer wavelength by diffusing donor material into the hologram in a controlled manner.
