Abstract: A nanovoided spacer material that is used as a mechanical buffer between at least two optical components. The optical components may include gratings (e.g., Bragg gratings, moth-eye surfaces, etc.) having sensitive and fragile surfaces (e.g., patterned surfaces). The nanovoided spacers may have a predetermined thickness and concentration of nanovoids to provide a given optical property (e.g., a reflection coefficient at an interface between two optical elements). The nanovoided spacer may include a multilayer structure (e.g., two or more layers) of varying refractive index (e.g., to reduce reflections between surfaces of the optical elements). The nanovoided spacer may include from about 10% to 90% nanovoids by volume and may have an average index of refraction of about 1.15. Various other methods, systems, apparatuses, and materials are also disclosed.

Abstract: A casting method involves providing a precursor to a mold that includes a deformable surface overlying a chamber, shaping the deformable surface according to a surface profile by adjusting a fluid pressure within the chamber and driving one or more actuators that are configured to distort the deformable surface, and solidifying the precursor while the deformable surface is shaped according to the surface profile to form an optical element.

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.

Abstract: An optical system includes an illumination layer, an optical combiner, and an active optics block. The illumination layer includes an array of point light sources configured to emit calibration light. The optical combiner is configured to pass visible light to a front side of the optical system and to direct the calibration light to a camera that generates an image in response to the calibration light. The image includes an array of points corresponding to the array of point light sources. The active optics block includes an adjustable lens disposed between the illumination layer and the optical combiner and is configured to pass the calibration light to the optical combiner and to focus the visible light. The active optics block is further configured to adjust an optical power of the adjustable lens based on the image of the array of points.

Abstract: In some examples, a device includes a fluid lens having a substrate and a membrane connected to the substrate using a flexure. The fluid lens may include a fluid located within a cavity at least partially defined by the substrate and the membrane. The flexure may include a membrane attachment and an elastic element. The device may be configured so that a displacement of the membrane attachment adjusts a profile of the membrane, and may induce a compression of at least a portion of the elastic member. In some examples, a flexure may include a plurality of elastic elements, which may be attached to the substrate (e.g., through a flexure support), and a rigid element, that may include or be connected to the membrane attachment. Example devices include head-mounted devices, such as augmented reality or virtual reality devices.

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.
