Abstract:

Method for treating thermoplastic to make a surface thereof superhydrophobic. The method includes exposing the thermoplastic to a specific solvent for a selected time period. It is preferred that the treatment time be in the range of one minute to approximately five hours and more preferably in the range of one minute to 15 minutes. Thermoplastics and solvents having a similar solubility parameter interact with one another to form hydrophobic hierarchical surfaces.

F21V 8/00

Abstract:

An actuator aligned multi-channel projector assembly generates image light using a plurality of projectors. A projector includes a plurality of optical components in optical series and one or more actuators. The plurality of optical components include a light source and a plurality of optical elements. The light source generates first light. The plurality of optical elements project the first light. The first light is output from the projector and combined with a second to form an image presented via a display element of a headset to a user. The one or more actuators adjust a position of at least one optical component of the plurality of optical components relative to another optical component in order to compensate for misalignment of a portion of the image formed from the first light relative to a portion of the image formed from the second light.

Abstract:

A method may include stretching a deformable bounding element into a stretched state. The method may further include coating the deformable bounding element with at least one layer of an anti-reflective material while the deformable bounding element is in the stretched state and assembling an optical lens assembly including the deformable bounding element, such that the optical lens assembly adjusts at least one optical property by controlling a shape of the deformable bounding element. The deformable bounding element may have less tension when in a neutral state than the deformable bounding element has when in the stretched state. The method may additionally include coating the deformable bounding element with at least one layer of an anti-reflective material while the deformable bounding element is not in a stretched state. Various other apparatuses, systems, and methods are also disclosed.

International Classification:

G02B 26/08
G02B 27/28
G02B 26/10
G09G 3/02

Abstract:

Unwanted reflections in a polarization diversity based optical beam scanner of a projector display may be reduced by mounting a quarter-wave plate optically in contact with the scanning mirror. This lowers the amplitude of the reflection from a rear surface of the quarter-wave plate. A residual reflection from the quarter-wave plate to mirror interface will be scanned with the main scanned light beam, reducing brightness and noticeability of image artifacts caused by undesired or spurious reflections in the optical beam scanner.

Abstract:

The disclosed embodiments are generally directed to optical systems. The optical systems may include a proximal lens that may transmit light toward an eye of a user. The optical systems may also include a distal lens that may, in combination with the proximal lens, correct for at least a portion of a refractive error of the eye of the user. The optical systems may further include a selective transmission interface. The selective transmission interface may couple the proximal lens to the distal lens, transmits light having a selected property, and does not transmit light that does not have the selected property. The optical system can also include an accommodative lens, such as a liquid lens. Various other methods, systems, and computer-readable media are also disclosed.

Abstract:

An actuator assembly includes a primary electrode, a secondary electrode overlapping at least a portion of the primary electrode, and an electroactive polymer layer disposed between the primary electrode and the secondary electrode, where the electroactive polymer layer includes a non-vertical (e.g., sloped) sidewall with respect to a major surface of at least one of the electrodes. The electroactive polymer layer may be characterized by a non-axisymmetric shape with respect to an axis that is oriented orthogonal to an electrode major surface.

International Classification:

G02F 1/03
G02F 1/055

Abstract:

A transparent optical element may include a layer of an electroactive ceramic disposed between transparent electrodes, such that the electrodes are each oriented perpendicular to a non-polar direction of the ceramic layer. Optical properties of the optical element, including transmissivity, haze, and clarity may be improved by the application of a voltage to the electroactive ceramic, and an associated phase transformation.
