US Patent:

20210286171, Sep 16, 2021

Filed:

Mar 8, 2021

Appl. No.:

17/195435

Inventors:

- Plantation FL, US
Clinton Carlisle - Parkland FL, US
Jason Schaefer - Coral Springs FL, US
Andrew C. Duenner - Houston TX, US
Vaibhav Mathur - Weston FL, US

Assignee:

Magic Leap, Inc. - Plantation FL

International Classification:

G02B 26/10
G02B 6/02

Abstract:

Described are optical fibers and scanning fiber displays comprising optical fibers. The disclosed optical fibers include a plurality of mass adjustment regions, such as gas-filled regions, positioned between a central waveguiding element and an outer periphery for reducing a mass of the optical fiber as compared to an optical fiber lacking the plurality of mass adjustment regions.

International Classification:

G02B 27/01
G02B 27/00
G06T 19/00

Abstract:

Methods and systems for depth-based foveated rendering in the display system are disclosed. The display system may be an augmented reality display system configured to provide virtual content on a plurality of depth planes using different wavefront divergence. Some embodiments include monitoring eye orientations of a user of a display system based on detected sensor information. A fixation point is determined based on the eye orientations, the fixation point representing a three-dimensional location with respect to a field of view. Location information of virtual objects to present is obtained, with the location information indicating three-dimensional positions of the virtual objects. Resolutions of at least one virtual object is adjusted based on a proximity of the at least one virtual object to the fixation point. The virtual objects are presented to a user by display system with the at least one virtual object being rendered according to the adjusted resolution.

International Classification:

F21V 8/00
G02B 5/18
G02B 27/01

Abstract:

A device includes an input coupling grating having a first grating structure characterized by a first set of grating parameters. The input coupling grating is configured to receive light from a light source. The device also includes an expansion grating having a second grating structure characterized by a second set of grating parameters varying in at least two dimensions. The second grating structure is configured to receive light from the input coupling grating. The device further includes an output coupling grating having a third grating structure characterized by a third set of grating parameters. The output coupling grating is configured to receive light from the expansion grating and to output light to a viewer.
