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 wearable display system includes an eyepiece stack having a world side and a user side opposite the world side. During use, a user positioned on the user side views displayed images delivered by the wearable display system via the eyepiece stack which augment the user's field of view of the user's environment. The system also includes an optical attenuator arranged on the world side of the of the eyepiece stack, the optical attenuator having a layer of a birefringent material having a plurality of domains each having a principal optic axis oriented in a corresponding direction different from the direction of other domains. Each domain of the optical attenuator reduces transmission of visible light incident on the optical attenuator for a corresponding different range of angles of incidence.

Abstract: Described are optical fibers and scanning fiber displays comprising optical fibers. The disclosed optical fibers include a plurality of mass adjustment regions, such as gas-filled regions, positioned between a central waveguiding element and an outer periphery for reducing a mass of the optical fiber as compared to an optical fiber lacking the plurality of mass adjustment regions.

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.
