Abstract: An apparatus, system, and method for micro-electro-mechanical system (MEMS) micromirror including a plurality of stiffening structures is described. The MEMS micromirror includes a mirror surface to reflect light, a support platform coupled along a mirror surface, and a plurality of stiffening structures formed from or coupled to the support platform. In some examples, a dimensionality or density of the stiffening structures scale across an area of the support platform in a manner to assist in keeping the mirror surface flat under torsional force.

Abstract: The disclosed optical lens assemblies may include a deformable element, a structural support element, a substantially transparent deformable medium positioned between the deformable element and the structural support element, a compliant peripheral component positioned between peripheral portions of the deformable element and the structural support element, and an actuator configured to displace at least a portion of the compliant peripheral component to deform the deformable element and change at least one optical property of the optical lens assembly. Related head-mounted displays and methods of fabricating such optical lens assemblies are also disclosed.

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.

Abstract: A method may include bonding a deformable bounding element to a structural support element in which the deformable bounding element and a cavity-adjacent side of the structural support element define a cavity. The method may further include filling the cavity with a deformable medium by injecting the deformable medium past a cavity-opposite side of the structural support element and toward the cavity-adjacent side of the structural support element. The method may additionally include sealing an entry point of the injection of the deformable medium into the cavity. Various other apparatuses, systems, and methods are also disclosed.

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: The disclosed optical lens assemblies may include a deformable element, a structural support element, and a compliant interface material that is disposed between and couples at least a portion of the deformable element and the structural support element. The deformable element may, when deformed, alter an optical property of the optical lens assembly. The compliant interface material may be configured to compensate for a difference between a physical property of the deformable element and the structural support element. Related head-mounted displays and methods are also disclosed.

Abstract: A direct drive scanning micromirror includes a mirror body defining a mirror surface, and a plurality of curved cantilevers that each extend directly from the mirror body. The shape of the cantilevers and the geometry of the interface between the cantilevers and the mirror body are configured to decrease peak stresses within the micromirror during operation, which may beneficially impact performance and lifetime.
