Abstract: Apparatus for deflection of a beam of light includes a case, which is configured to be positioned in a path of the beam, and a liquid, which is contained within the case. An array of plates is disposed across a surface of the liquid. The plates are configured to rotate on the surface about respective axes, which are mutually parallel and are spaced apart by a predefined pitch. An actuator is configured to drive a rotation of the plates about the respective axes so as deflect the beam that is incident on the plates.

Abstract: An optical component includes a substrate and a piezoelectric film formed on the substrate and configured to deform in response to an actuation voltage applied thereto into a pattern of peaks and troughs configured to deflect optical radiation that is incident thereon. The pattern has an amplitude determined by the actuation voltage.

Abstract: A head-mounted device may have lenses. A user may view images through the lenses from eye boxes. The lenses may be tunable liquid lenses. Each lens may have a lens chamber. The lens chamber of the lens may have rigid and/or flexible walls that form optical lens surfaces. Actuators and/or pump and reservoir systems may deform the lens surfaces in response to control signals from a control circuit to tune the lens. Each liquid lens may have oil or other liquid in the lens chamber for that lens. Inorganic dielectric particles or other refractive-index-adjustment particles may be used to adjust the refractive index of the lens. The particles may be subwavelength in size.

Abstract: In some embodiments, the camera system comprises: an optical assembly to create an optical image from the optical wavefront; a deformable phase plate (DPP) to receive the optical image from the optical assembly and to adjust the optical image in accordance with a control signal, the DPP including a deformable surface suspended over a cavity filled with optical fluid, and electrical actuation elements configured to change a shape of the deformable surface based on the control signal, the electrical actuation elements arranged in a pattern in the cavity and, when activated, provide an electrostatic force on the deformable surface; an image sensor to convert the adjusted optical image into electrical signals; an image signal processor to generate a digital image from the electrical signals; and an estimator to estimate an aberration or tilt correction of the digital image and to generate the control signal based on the estimated aberration or tilt correction.
