摘要： An example apparatus may include a display and an optical configuration configured to provide an image of a display, for example, in a head-mounted device. An example apparatus may include a display and an optical configuration including a first lens assembly and a second lens assembly. The first lens assembly may include a first lens, a first reflector, and an actuator. The second lens assembly may include a second lens and a second reflector. An example apparatus may include a controller configured to apply at least one electrical signal to the actuator to control the optical power of the first lens. The display light may pass through the actuator, which may be transparent and may include a plurality of actuator layers. Other devices, methods, systems and computer-readable media are also disclosed.

摘要： An actuator may be integrated into an optical element such as a liquid lens and configured to create spherical curvature as well as a variable cylinder radius and axis in a surface of the optical element. An example actuator may include a stack of electromechanical layers, and electrodes configured to apply an electric field independently across each of the electromechanical layers. Within the stack, an orientation of neighboring electromechanical layers may differ, e.g., stepwise, by at least approximately 10°.

摘要： An eye-tracking device includes an optical device that includes a light source with an optical cavity and a light sensor. The light source is positioned to output coherent light toward an eye of a user and receive at least a portion of the coherent light back from the eye of the user as feedback light. The feedback light enters the optical cavity and causes modulation of an intensity of the coherent light. The light sensor is optically coupled with the light source for detecting the modulated intensity of the coherent light and generating one or more signals based on the detected intensity of the coherent light. The eye-tracking device also includes one or more processors that are coupled to the optical device for determining, from the one or more signals, movement information of the eye. A method of detecting movement of an eye using the eye-tracking device is also disclosed.

摘要： A polymer layer includes a first in-plane refractive index extending along a first direction of the polymer layer, a second in-plane refractive index less than the first in-plane refractive index extending along a second direction of the polymer layer orthogonal to the first direction, a third refractive index along a direction orthogonal to both the first direction and the second direction, and a plurality of wrinkles extending along a surface of the polymer layer, where a difference between the first in-plane refractive index and the second in-plane refractive index is at least approximately 0.05, and the third refractive index is greater than the second in-plane refractive index.

摘要： An example apparatus may include a display and an optical configuration configured to provide an image of the display. The optical configuration may include a lens having a lens surface that supports at least one serpentine electrode. The at least one serpentine electrode may be in electrical communication with an electrical component such as an electrooptical component (e.g., including at least one of a laser, light-emitting diode, photodiode, or image sensor) or an electroactive component that may show one or more dimensional changes under application of an electric field. An example apparatus may also include a controller in electrical communication with the electrical component through the at least one serpentine electrode. In some examples, the serpentine electrode may have an approximately sinusoidal shape. Other devices, methods, systems, and computer-readable media are also disclosed.
