Patent number: 11898836Abstract: Examples of a light field metrology system for use with a display are disclosed. The light field metrology may capture images of a projected light field, and determine focus depths (or lateral focus positions) for various regions of the light field using the captured images. The determined focus depths (or lateral positions) may then be compared with intended focus depths (or lateral positions), to quantify the imperfections of the display. Based on the measured imperfections, an appropriate error correction may be performed on the light field to correct for the measured imperfections. The display can be an optical display element in a head mounted display, for example, an optical display element capable of generating multiple depth planes or a light field display.Type: GrantFiled: November 28, 2022Date of Patent: February 13, 2024Assignee: Magic Leap, Inc.Inventors: Ivan Li Chuen Yeoh, Lionel Ernest Edwin, Samuel A.

Patent number: 11902677Abstract: An image sensor suitable for use in an augmented reality system to provide low latency image analysis with low power consumption. The augmented reality system can be compact, and may be small enough to be packaged within a wearable device such as a set of goggles or mounted on a frame resembling ordinary eyeglasses. The image sensor may receive information about a region of an imaging array associated with a movable object and selectively output imaging information for that region. The region may be updated dynamically as the image sensor and/or the object moves. Such an image sensor provides a small amount of data from which object information used in rendering an augmented reality scene can be developed. The amount of data may be further reduced by configuring the image sensor to output indications of pixels for which the measured intensity of incident light changes.Type: GrantFiled: October 30, 2019Date of Patent: February 13, 2024Assignee: Magic Leap, Inc.Inventors: Martin Georg Zahnert, Alexander Ilic, Erik Fonseka
