Abstract: An example apparatus includes an optical fiber, an actuator, and a joint mechanically coupling the actuator to the optical fiber. The joint includes a neck extending along an axis. The optical fiber is threaded through an aperture extending along the axis through the neck. The optical fiber is attached to the joint at a surface of the neck facing the axis. The joint also includes a collar extending along the axis. The actuator is mechanically attached to the joint at an inner surface of the collar facing the axis. The joint also includes a flexural element extending radially from the neck to the collar. During operation, the joint couples a force from the actuator to the optical fiber to vary an orientation of a portion of the optical fiber extending from the neck with respect to the axis.

Abstract: In some implementations, an optical device includes a one-way mirror formed by a polarization selective mirror and an absorptive polarizer. The absorptive polarizer has a transmission axis aligned with the transmission axis of the reflective polarizer. The one-way mirror may be provided on the world side of a head-mounted display system. Advantageously, the one-way mirror may reflect light from the world, which provides privacy and may improve the cosmetics of the display. In some implementations, the one-way mirror may include one or more of a depolarizer and a pair of opposing waveplates to improve alignment tolerances and reduce reflections to a viewer. In some implementations, the one-way mirror may form a compact integrated structure with a dimmer for reducing light transmitted to the viewer from the world.

Abstract: A head-mounted apparatus include an eyepiece that include a variable dimming assembly and a frame mounting the eyepiece so that a user side of the eyepiece faces a towards a user and a world side of the eyepiece opposite the first side faces away from the user. The dynamic dimming assembly selectively modulates an intensity of light transmitted parallel to an optical axis from the world side to the user side during operation. The dynamic dimming assembly includes a variable birefringence cell having multiple pixels each having an independently variable birefringence, a first linear polarizer arranged on the user side of the variable birefringence cell, the first linear polarizer being configured to transmit light propagating parallel to the optical axis linearly polarized along a pass axis of the first linear polarizer orthogonal to the optical axis, a quarter wave plate arranged between the variable birefringence cell and the first linear polarizer, a fast axis of the quarter wave plate being arranged relative to the pass axis of the first linear polarizer to transform linearly polarized light transmitted by the first linear polarizer into circularly polarized light, and a second linear polarizer on the world side of the variable birefringence cell.

Abstract: A wearable display system includes an eyepiece stack having a world side and a user side opposite the world side, wherein during use a user positioned on the user side views displayed images delivered by the system via the eyepiece stack which augment the user's view of the user's environment. The wearable display system also includes an angularly selective film arranged on the world side of the of the eyepiece stack. The angularly selective film includes a polarization adjusting film arranged between pair of linear polarizers. The linear polarizers and polarization adjusting film significantly reduces transmission of visible light incident on the angularly selective film at large angles of incidence without significantly reducing transmission of light incident on the angularly selective film at small angles of incidence.

Abstract: Techniques are described for operating an optical system. In some embodiments, light associated with a world object is received at the optical system. Virtual image light is projected onto an eyepiece of the optical system. A portion of a system field of view of the optical system to be at least partially dimmed is determined based on information detected by the optical system. A plurality of spatially-resolved dimming values for the portion of the system field of view may be determined based on the detected information. The detected information may include light information, gaze information, and/or image information. A dimmer of the optical system may be adjusted to reduce an intensity of light associated with the world object in the portion of the system field of view according to the plurality of dimming values.

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: Methods and systems for depth-based foveated rendering in the display system are disclosed. The display system may be an augmented reality display system configured to provide virtual content on a plurality of depth planes using different wavefront divergence. Some embodiments include determining a fixation point of a user's eyes. Location information associated with a first virtual object to be presented to the user via a display device is obtained. A resolution-modifying parameter of the first virtual object is obtained. A particular resolution at which to render the first virtual object is identified based on the location information and the resolution-modifying parameter of the first virtual object. The particular resolution is based on a resolution distribution specifying resolutions for corresponding distances from the fixation point. The first virtual object rendered at the identified resolution is presented to the user via the display system.
