Publication number: 20200201026Abstract: Techniques for artifact mitigation in an optical system are disclosed. Light associated with a world object is received at the optical system, which is characterized by a world side and a user side. Light associated with a virtual image is projected onto an eyepiece of the optical system, causing a portion of the light associated with the virtual image to propagate toward the user side and light associated with an artifact image to propagate toward the world side. A dimmer of the optical system positioned between the world side and the eyepiece is adjusted to reduce an intensity of the light associated with the artifact image impinging on the dimmer and an intensity of the light associated with the world object impinging on the dimmer.Type: ApplicationFiled: December 17, 2019Publication date: June 25, 2020Applicant: Magic Leap, Inc.Inventors: Kevin Richard Curtis, Samarth Bhargava, Bradley Jay Sissom, Victor Kai Liu, Chulwoo Oh, Ravi Kumar Komanduri, Kevin Messer

Publication number: 20190238826Abstract: In some embodiments, optical systems with a reflector and a lens proximate a light output opening of the reflector provide light output with high spatial uniformity and high efficiency. The reflectors are shaped to provide substantially angularly uniform light output and the lens is configured to transform this angularly uniform light output into spatially uniform light output. The light output may be directed into a spatial light modulator, which modulates the light to project an image.Type: ApplicationFiled: April 8, 2019Publication date: August 1, 2019Inventors: Bradley Jay Sissom, Heidi Leising Hall, Kevin Curtis

Publication number: 20190179149Abstract: An optical system for an augmented reality head mounted display eyepiece that is configured to deliver images to the eye wherein the optical system includes optics. The optics are disposed so as to receive light output from the light source. The optics further arranged with respect to a spatial light modulator such that the light received from the light source passes through the optics and illuminates the spatial light modulator. The light illuminating the spatial light modulator is redirected back through the optics and is coupled into at least one waveguide through at least one in-coupling optical element. At least a portion of the coupled light is ejected from at least one waveguide by at least one out-coupling optical element and directed to the eye of the user.Type: ApplicationFiled: December 10, 2018Publication date: June 13, 2019Inventors: Kevin Richard Curtis, Bradley Jay Sissom, Hui-Chuan Cheng, Miller Harry Schuck, III, Samarth Bhargava, Erik Heath Arend

Publication number: 20140204437Abstract: Systems and methods for dynamic aperture holographic multiplexing are disclosed. One example process may include recording a set of holograms in a recording medium by varying both the reference beam angular aperture and the signal beam angular aperture. The angular aperture of the signal beam may be dynamically changed such that the closest edge of each signal beam angular aperture is selected to be a threshold angle different than the angular aperture of the reference beam used to record it. In some examples, the dynamic aperture holographic multiplexing process may include dynamic aperture equalization to reduce cross-talk, to improve error correction parity distribution for improved recovery transfer rate, to provide multiple locus aperture sharing for increased recording density, and to provide polarization multiplexed shared aperture multiplexing for increased transfer rate in both recording and recovery.Type: ApplicationFiled: May 1, 2013Publication date: July 24, 2014Applicant: AKONIA HOLOGRAPHICS LLCInventors: Mark R.
