Patent number: 11815854Abstract: An optical master is created by using a nanoimprint alignment layer to pattern a liquid crystal layer. The nanoimprint alignment layer and the liquid crystal layer constitute the optical master. The optical master is positioned above a photo-alignment layer. The optical master is illuminated and light propagating through the nanoimprinted alignment layer and the liquid crystal layer is diffracted and subsequently strikes the photo-alignment layer. The incident diffracted light causes the pattern in the liquid crystal layer to be transferred to the photo-alignment layer. A second liquid crystal layer is deposited onto the patterned photo-alignment layer, which subsequently is used to align the molecules of the second liquid crystal layer. The second liquid crystal layer in the patterned photo-alignment layer may be utilized as a replica optical master, or as a diffractive optical element for directing light in optical devices such as augmented reality display devices.Type: GrantFiled: November 20, 2020Date of Patent: November 14, 2023Assignee: Magic Leap, Inc.Inventors: Ravi Kumar Komanduri, Chulwoo Oh

Patent number: 11815688Abstract: A display system is configured to direct a plurality of parallactically-disparate intra-pupil images into a viewer's eye. The parallactically-disparate intra-pupil images provide different parallax views of a virtual object, and impinge on the pupil from different angles. In the aggregate, the wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The amount of parallax disparity may be selected using an array of shutters that selectively regulate the entry of image light into an eye. Each opened shutter in the array provides a different intra-pupil image, and the locations of the open shutters provide the desired amount of parallax disparity between the images. In some other embodiments, the images may be formed by an emissive micro-display.Type: GrantFiled: March 28, 2022Date of Patent: November 14, 2023Assignee: Magic Leap, Inc.Inventor: Michael Anthony Klug

Patent number: 11811011Abstract: In some embodiments, an interconnect electrical connects a light emitter to wiring on a substrate. The interconnect may be deposited by 3D printing and lays flat on the light emitter and substrate. In some embodiments, the interconnect has a generally rectangular or oval cross-sectional profile and extends above the light emitter to a height of about 50 ?m or less, or about 35 ?m or less. This small height allows close spacing between an overlying optical structure and the light emitter, thereby providing high efficiency in the injection of light from the light emitter into the optical structure, such as a light pipe.Type: GrantFiled: February 14, 2022Date of Patent: November 7, 2023Assignee: MAGIC LEAP, INC.Inventor: Kevin Curtis

Patent number: 11809613Abstract: A high-resolution image sensor suitable for use in an augmented reality (AR) system to provide low latency image analysis with low power consumption. The AR 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, selectively output imaging information for that region, and synchronously output high-resolution image frames. The region may be updated dynamically as the image sensor and/or the object moves. The image sensor may output the high-resolution image frames less frequently than the region being updated when 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 AR scene can be developed.Type: GrantFiled: October 30, 2019Date of Patent: November 7, 2023Assignee: Magic Leap, Inc.Inventors: Martin Georg Zahnert, Alexander Ilic
