摘要： A display subsystem for a virtual image generation system comprises a planar waveguide apparatus, an optical fiber, at least one light source configured for emitting light from a distal end of the optical fiber, and a mechanical drive assembly to which the optical fiber is mounted as a fixed-free flexible cantilever. The drive assembly is configured for displacing a distal end of the optical fiber about a fulcrum in accordance with a scan pattern, such that the emitted light diverges from a longitudinal axis coincident with the fulcrum. The display subsystem further comprises an optical modulation apparatus configured for converging the light from the optical fiber towards the longitudinal axis, and an optical waveguide input apparatus configured for directing the light from the optical modulation apparatus down the planar waveguide apparatus, such that the planar waveguide apparatus displays one or more image frames to an end user.

摘要： An optical fiber assembly is provided including an optical fiber and a beam shaping component affixed to an extremity of the optical fiber. The optical fiber supports a guided mode having a spatial profile defining a first shape. The beam shaping component defines a light path and has a transversal refractive index profile including an outer refractive index value greater than an inner refractive index value. The beam shaping component transforms the spatial profile of a light beam propagating along the light path between the first shape and a second shape different from the first shape. The optical assembly may for example transform a Gaussian light beam into a flat-top or donut shape.

摘要： In accordance with one aspect of my invention, the core and cladding regions of a hollow-core optical fiber arc configured so that a signal mode is coupled to a cladding mode in order to exploit polarization-dependent properties. In general, the fiber comprises a hollow-core region surrounded by a cladding region, which includes a localized hollow-waveguide region. The core and waveguide regions are configured so that the coupling between a signal mode in the core region and a cladding mode in the waveguide region are phase-matched for efficient coupling, and the phase-matching condition is made polarization-dependent to provide improved control of the fiber's polarization dependent properties. In a preferred embodiment, the cladding region comprises a bandgap structure. In one embodiment, the at least one region has a non-symmetric cross-sectional shape (e.g., oblong) with respect to one of its transverse axes. In an alternative embodiment, both the core region and the waveguide region are non-symmetric but with respect to orthogonal axes. In another embodiment, the at least one region has a multiplicity of micro-defects disposed at or near the periphery thereof and in a non-rotationally-symmetric pattern. In an alternative embodiment, both the core region and the waveguide region include a multiplicity of micro-defects at or near the periphery thereof in a non-rotationally-symmetric pattern. Optical fibers of this type find application in polarization-dependent optical couplers (e.g., splitters, polarizers) and in sensors.

摘要： A delivery device that is usable in a laser peening operation emits a columnar flow of a fluid that contains therein a beam of electromagnetic energy. The beam is retained within the interior of the flow of fluid since the total internal reflectivity of the flow is sufficient to do so. The flow of fluid that serves as a conduit for the beam also itself impinges on a workpiece and thus contains and washes away the plasma that forms from a laser peening operation, and this resists the plasma from reaching and possibly damaging the delivery device. The carrying of the beam in the columnar flow of fluid avoids the need to maintain a fixed distance between the delivery device and the workpiece, which simplifies the movement by a robotic manipulator of the delivery device along a non-planar surface of a workpiece during a laser peening operation.

摘要： A sample can be illuminated for analysis using apparatus including a light source, a planar waveguide, and a refractive volume. The light source provides light along a propagation vector. The planar waveguide is oriented such that the propagation vector is perpendicular to the normal vector of the planar waveguide and offset from the planar waveguide in a direction parallel to the normal vector of the planar waveguide. The refractive volume is positioned proximate to the planar waveguide and can optically coupling light provided by the light source to the planar waveguide.

摘要： An image combiner, also referred to as a combiner optic, of a near-eye display system or the like transmits enough light so a user can see remote objects in a "world view", while also reflecting enough light so the user can simultaneously see a projected image in a "projected" (augmented) view. The disclosed image combiners use two partial reflectors configured to form a wedged reflective cavity. In the display system, light from an imaging device follows a path to the user's eye that includes three reflections in the wedged cavity. By using this capability of the wedged cavity, the combiner optic can have a substantially reduced thickness, and lower profile, than a combiner optic that uses only one partial reflector and only one reflection in the optical path.
