Patent number: 10890465Abstract: An apparatus is disclosed for capturing image information. The apparatus includes a waveguide having opposed planar input and output faces. A diffractive optical element (DOE) is formed across the waveguide. The DOE is configured to couple a portion of the light passing through the waveguide into the waveguide. The light coupled into the waveguide is directed via total internal reflection to an exit location on the waveguide. The apparatus further includes a light sensor having an input positioned adjacent the exit location of the waveguide to capture light exiting therefrom and generate output signals corresponding thereto. A processor determines the angle and position of the coupled light with respect to the input face of the waveguide based on the output signals.Type: GrantFiled: July 27, 2018Date of Patent: January 12, 2021Assignee: Magic Leap, Inc.Inventor: Adrian Kaehler

Patent number: 10884199Abstract: A first optical axis of a first optical component is caused to be at a first angle with respect to a first precision surface of the first optical component. A second optical axis of a second optical component is aligned to be at a second angle to a second flat surface of the second optical component. The second angle is equal to or derived from the first angle. The first and second flat surfaces are caused to directly face each other to allow only sliding motion between the first and second flat surfaces. The sliding motion is performed between the first and second flat surfaces until the first and second optical axes are sufficiently collinear.Type: GrantFiled: January 9, 2019Date of Patent: January 5, 2021Assignee: Canon U.S.A., Inc.Inventors: Alexander Altshuler, Daisuke Yamada
