Abstract: A light reflection assembly includes a reflection element, a substrate, a first cantilever beam, a second cantilever beam, a magnetic structure, and a support structure. The substrate is located on the magnetic structure, the reflection element is located in a hollow region in the middle of the substrate. Two ends of the reflection element are connected to the substrate through the first cantilever beam and the second cantilever beam, respectively. The first cantilever beam and second cantilever beam are located on different sides of the reflection element and are disposed along a first axial direction. A front side of the reflection element is configured to reflect incident light. The magnetic structure is configured to drive the reflection element to rotate. The support structure is fastened to the magnetic structure. An end of the support structure is in contact with a back side of the reflection element.

Abstract: An optical image stabilization apparatus includes a first lens, a first reflector, a position sensor, a control component, and a housing configured to enclose the first lens and the first reflector, where the position sensor is connected to the control component. An optical signal is transmitted to the first reflector after passing through the first lens. The first reflector reflects the received optical signal, and the reflected optical signal is projected onto an imaging plane. The position sensor is configured to detect shaking information of the first lens and send the shaking information to the control component. The control component is configured to control, based on the shaking information, the first reflector to rotate by using a first preset direction as an axis, where the first preset direction is a direction that is not parallel to a normal direction of the first reflector.

Abstract: Embodiments of this application disclose example optical acquisition, tracking, pointing (ATP) antennas, to implement distribution of an annular Gaussian beam by using an axicon. One example optical ATP antenna includes an input light source, an axicon, and an optical imaging assembly, and central axes of the input light source, the axicon, and the optical imaging assembly coincide. The axicon is configured to: shape a first Gaussian beam emitted by the input light source into a first annular Gaussian beam, and transmit the first annular Gaussian beam to the optical imaging assembly. The optical imaging assembly is configured to: expand the first annular Gaussian beam into a second annular Gaussian beam, and transmit the second annular Gaussian beam to a lower optical path, where a diameter of the second annular Gaussian beam is greater than a diameter of the first annular Gaussian beam.

Abstract: A lens, glasses, and a lens adjustment method are provided. The lens includes a first lens layer. The first lens layer includes a plurality of liquid crystal regions. At least one liquid crystal region forms a first optical region. At least one liquid crystal region forms a second optical region. Optical powers of the liquid crystal regions may be changed by controlling rotation of liquid crystal molecules in the liquid crystal regions separately included in the first optical region and the second optical region, so that an optical power of the first optical region can be different from an optical power of the second optical region.
