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: 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.

Abstract: An optically clear, high strength, high modulus, and high thermal conductivity polyethylene thin film may be formed from a crystallizable polymer and an additive configured to interact with the crystallizable polymer to facilitate crystallite alignment and, in some examples, create a higher crystalline content within the polyethylene thin film. The polyethylene thin film may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 5% of the molecular weight of the crystallizable polymer. Example crystallizable polymers may include high molecular weight polyethylene, high density polyethylene, and ultra-high molecular weight polyethylene. Example additives may include low molecular weight polyethylene and polyethylene oligomers. The polyethylene thin film may be characterized by a Young's modulus of at least approximately 10 GPa, a tensile strength of at least approximately 0.7 GPa, and a thermal conductivity of at least approximately 5 W/mK.

Abstract: A polymer thin film includes polyvinylidene fluoride (PVDF) and is characterized by a Young's modulus along an in-plane dimension of at least 4 GPa, an electromechanical coupling factor (k31) of at least 0.1 at room temperature. A method of manufacturing such a polymer thin film may include forming a polymer composition into a polymer thin film, applying a tensile stress to the polymer thin film along at least one in-plane direction and in an amount effective to induce a stretch ratio of at least approximately 5 in the polymer thin film, and applying an electric field across a thickness dimension of the polymer thin film. Annealing and poling steps may separately or simultaneously accompany and/or follow the act of stretching of the polymer thin film.

Abstract: Disclosed herein are techniques for eye illumination for eye position tracking. An illuminator for eye tracking includes a substrate configured to be placed in front of an eye of a user and a light source positioned on a surface of the substrate. The light source is configured to be positioned within a field of view of the eye of the user. A maximum dimension of the light source in a plane parallel to an emission surface of the light source is less than 500 μm.

Abstract: A graded-index optical element may include a nanovoided material including a first surface and a second surface opposite the first surface. The nanovoided material may be transparent between the first surface and the second surface. Additionally, the nanovoided material may have a predefined change in effective refractive index in at least one axis due to a change in at least one of nanovoid size or nanovoid distribution along the at least one axis. Various other elements, devices, systems, materials, and methods are also disclosed.

Abstract: A polymer article includes an at least partially disentangled polyvinylidene fluoride (PVDF) family member composition and is characterized by an elastic modulus of at least 4 GPa and an electromechanical coupling factor (k31) of at least 0.1 at room temperature. A method of manufacturing such a polymer article may include forming an at least partially disentangled polymer composition into a polymer thin film or fiber, applying a tensile stress to the polymer article in an amount effective to induce a stretch ratio of at least approximately 5 in the thin film or fiber, and applying an electric field across a thickness dimension of the polymer article. Annealing and poling steps may separately or simultaneously accompany and/or follow the act of stretching.
