摘要： 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.

摘要： A method of fabricating a variable diameter fiber includes providing a fiber optic cable, focusing a laser beam at a predetermined location inside the fiber optic cable, and creating a damage site at the predetermined location. The method also includes focusing the laser beam at a series of additional predetermined locations inside the fiber optic cable and creating a plurality of additional damage sites at the additional predetermined locations. The damage site and the additional damage sites define a variable diameter profile. The method further includes exposing the fiber optic cable to an etchant solution, preferentially etching the damage site and the plurality of additional damage sites, and separating a portion of the fiber optic cable to release the variable diameter fiber.

摘要： A fiber optic element of a fiber scanning system includes a motion actuator having longitudinal side members, an internal orifice, a first support region, a central region, and a second support region. The fiber optic element also includes a first fiber optic cable passing through the internal orifice and having a first fiber joint as well as a second fiber optic cable passing through the internal orifice. The second fiber optic cable has a second fiber joint disposed in the central region and spliced to the first fiber joint, a second coupling region, a light delivery region, and a light emission tip. The light delivery region is characterized by a first diameter and the light emission tip is characterized by a second diameter less than the first diameter.

摘要： A method of operating an eyepiece waveguide includes directing light from a projector to impinge on an incoupling grating (ICG). The method also includes diffracting a first fraction of the light from the projector into a first portion of the eyepiece waveguide, propagating the first fraction of the light into a second portion of the eyepiece waveguide, and diffracting the first fraction of the light out of the eyepiece waveguide. The method further includes diffracting a second fraction of the light from the projector into the second portion of the eyepiece waveguide, propagating the second fraction of the light into the first portion of the eyepiece waveguide, and diffracting the second fraction out of the eyepiece waveguide.
