Publication number: 20240012247Abstract: Disclosed herein are systems and methods for providing waveguide display devices utilizing overlapping integrated dual action (IDA) waveguides. One embodiment includes a waveguide display device including: a first input image source providing first image light; a second input image source provide second image light; a first IDA waveguide; and a second IDA waveguide. The first IDA waveguide and the second IDA waveguide may include an overlapping region where a first two-dimensionally expanded first image light, a second two-dimensionally expanded first image light, a first two-dimensionally expanded second image light, and a second two-dimensionally expanded second image light is ejected towards an eyebox. Advantageously, resolution may be enhanced and field of view may be expanded through the use of overlapping IDA waveguides.Type: ApplicationFiled: June 2, 2023Publication date: January 11, 2024Applicant: DigiLens Inc.Inventors: Milan Momcilo Popovich, Alastair John Grant, Nima Shams, Jonathan David Waldern, Sihui He, Edward Lao, Roger Allen Conley Smith

Publication number: 20230213767Abstract: Methods and apparatus for eye-glow suppression in waveguide systems is disclosed herein. Some embodiments of the methods and the apparatus include a waveguide based display including a waveguide including an in-coupling optical element and an out-coupling optical element, where the in-coupling optical element is configured to in-couple image containing light and the out-coupling optical element is configured to out-couple the image counting light towards a user, where the waveguide comprises an outer surface and an inner surface opposite to the outer surface, and wherein the inner surface is closer to the user than the outer surface; and a partially light blocking layer above the outer surface of the waveguide opposite to the user, where the partially light blocking layer is configured to keep eye glow light from entering the environment outside the outer surface of the waveguide.Type: ApplicationFiled: May 26, 2021Publication date: July 6, 2023Applicant: DigiLens Inc.Inventors: Alastair John Grant, Milan Momcilo Popovich, Nicholas Sherwood, Roger Allen Conley Smith, Michiel Koen Callens, Nima Shams

Publication number: 20230061090Abstract: Various embodiments of this disclosure relate to a piecewise varying rolled K-vector grating structure including: a first grating section containing a grating with a first K-vector, a second grating section containing a grating with a second K-vector; and a first boundary region positioned between the first grating section and the second grating section. The first boundary region is a multiplexed grating region including both the first K-vector and the second K-vector. Further disclosed is a method for recording such a grating structure utilizing a holographic recording process. Providing a multiplexed grating in the first boundary region may largely remove line exposure artifacts between adjacent sections of the P-RKV grating.Type: ApplicationFiled: August 26, 2022Publication date: March 2, 2023Applicant: DigiLens Inc.Inventors: Milan Momcilo Popovich, Alastair John Grant, Roger Allen Conley Smith, Richard E.

Publication number: 20220197026Abstract: Methods and apparatus for eye-glow suppression in waveguide systems is disclosed herein. Some embodiments of the methods and the apparatus include a source of image modulated light; a waveguide having an eye-facing surface and an external surface facing the outside world; an input coupler for coupling the light into a total reflection internal path in the waveguide; at least one grating for providing beam expansion and extracting light from the waveguide towards an eyebox; a polymer grating structure comprising a modulation depth and a grating pitch. The modulation depth is greater than the grating pitch across at least a portion of the polymer grating structure. Advantageously, the polymer grating structure is configured to diffract light entering the waveguide from the outside world or stray light generated within the waveguide away from optical paths that are refracted through the external surface into the outside world.Type: ApplicationFiled: December 20, 2021Publication date: June 23, 2022Applicant: DigiLens Inc.Inventors: Alastair John Grant, Richard Bergstrom, Roger Allen Conley Smith, Michiel Koen Callens, Nicholas Sherwood, Nima Shams, Milan Momcilo Popovich
