Abstract: An eyepiece waveguide for an augmented reality display system includes a substrate having a first surface and a second surface and a diffractive input coupling element formed on or in the first surface or the second surface of the substrate. The diffractive input coupling element is configured to receive an input beam of light and to couple the input beam into the substrate as a guided beam. The eyepiece waveguide also includes a diffractive combined pupil expander-extractor (CPE) element formed on or in the first surface or the second surface of the substrate. The diffractive CPE element includes a first portion and a second portion divided by an axis. A first set of diffractive optical elements is disposed in the first portion and oriented at a positive angle with respect to the axis and a second set of diffractive optical elements is disposed in the second portion and oriented at a negative angle with respect to the axis.

Abstract: A waveguide display system may include an eyepiece waveguide that can have a first surface and a second surface, the waveguide including an incoupling diffractive optical element (DOE) and an outcoupling DOE. The waveguide display system may include a light source and a scanning mirror, and may include reflective and collimating optical elements. The incoupling DOE can be configured to selectively propagate incident light beams to the outcoupling DOE in the waveguide through total internal reflection (TIR).

Abstract: A method of fabricating a variable diameter fiber includes providing a fiber optic cable comprising a cladding region, a fiber core, and a plurality of sacrificial regions disposed in the cladding region and focusing a laser beam at a series of predetermined locations inside the fiber optic cable. The method also includes creating a series of damage sites associated with the series of predetermined locations, wherein the series of damage sites define a variable diameter profile and a latticework in the cladding region of the fiber optic cable. The method further includes exposing the fiber optic cable to an etchant solution, preferentially etching the series of damage sites, and separating peripheral portions of the fiber optic cable to release the variable diameter fiber.

Abstract: An augmented reality AR system and method for a retail experience include a waveguide apparatus that includes a planar waveguide and at least one optical diffraction element The AR retail system and method recognizes user location in a retail establishment, retrieves data corresponding to the retail establishment and generates virtual content relating to the retail establishment based on the retrieved data. The AR retail system and method creates a virtual user interface in a user's field of view. Virtual content is displayed on the virtual user interface while the user is engaged in retail activity and may be based on user input. The AR retail system and method may provide entertainment, facilitate the shopping experience, offer virtual coupons, render games based on locations throughout a store or based on a shopping list, provide information about food choices such as calorie counts, and identify metadata associated with items.

Abstract: An augmented reality system includes a light source configured to generate a virtual light beam. The system also includes a light guiding optical element having an entry portion, an exit portion, and a surface having a diverter disposed adjacent thereto. The light source and the light guiding optical element are configured such that the virtual light beam enters the light guiding optical element through the entry portion, propagates through the light guiding optical element by at least partially reflecting off of the surface, and exits the light guiding optical element through the exit portion. The light guiding optical element is transparent to a first real-world light beam. The diverter is configured to modify a light path of a second real-world light beam at the surface.

Abstract: A method for facilitating surgery using an augmented reality system, comprises retrieving patient data relating to a surgical procedure on a patient, generating virtual content comprising a virtual three-dimensional (3D) anatomical model based on the patient data, and displaying the virtual content, such that, when viewed by the first user, the virtual 3D anatomical model appears to be fixed at a physical location, whereby the virtual 3D anatomical model may be viewed by the first user from any angle or orientation merely by walking around the physical location.

Abstract: A waveguide display disposed in glasses includes a first pupil expander assembly operable to project a first image defined by a first field of view, and a second pupil expander assembly disposed adjacent the first pupil expander assembly and operable to project a second image defined by a second field of view different from the first field of view. The first pupil expander assembly is operable to emit light at a first non-zero angle with respect to a first emission plane associated with the first pupil expander assembly. The second pupil expander assembly is operable to emit light at a second non-zero angle with respect to a second emission plane associated with the second pupil expander assembly. The first non-zero angle is opposite to the second non-zero angle.
