Patent number: 11681362Abstract: Described herein are methods and display systems for enhanced eye tracking for display systems, such as augmented or virtual reality display systems. The display systems may include: a light source configured to output light and a moveable diffractive grating configured to reflect light from the light source, the reflected light forming a light pattern on the eye of the user; a plurality of light detectors to detect light reflected from the eye; and one or more processors. The display system changes the orientation of the diffractive grating, such that the light pattern reflected from the diffractive grating is scanned along an axis across the eye. Light intensity patterns are obtained via the light detectors, with a light intensity pattern representing a light detector signal obtained by detecting light reflected off of the eye as the light pattern is scanned across the eye.Type: GrantFiled: November 23, 2020Date of Patent: June 20, 2023Assignee: Magic Leap, Inc.Inventors: Nicolas Abele, Eric Chevallaz, Philippe De Gol, Julien Gamet, Gatien Cosendey, Stephan Arthur Gamper

Publication number: 20210382299Abstract: Described are two-dimensional scanning micromirror devices, scanning image display systems that incorporate a two-dimensional scanning micromirror device, and methods of projecting light using two-dimensional scanning micromirror devices. The disclosed two-dimensional scanning micromirror devices can be driven at or near the resonant oscillation frequency of the micromirror structure, which can result in lower power operation. In addition, by driving the micromirror structure at multiple different frequencies, the reflected light can be directed along a non-sinusoidal path, which can improve a tilt angle of the projected light compared with reflected light directed along a sinusoidal path.Type: ApplicationFiled: June 3, 2021Publication date: December 9, 2021Applicant: Magic Leap, Inc.Inventor: Julien Gamet
