摘要： A liquid lens can include a cavity, a first liquid disposed within the cavity, and a second liquid disposed within the cavity. A focus of the liquid lens can be adjustable by adjusting a shape of a variable interface defined by the first liquid and the second liquid. Upon adjusting the focus of the liquid lens in a periodic oscillation with a peak-to-valley amplitude of 20 diopter and a frequency of 2 Hz, a root mean square (RMS) wavefront error (WFE) of the liquid lens measured at 1 ms intervals can remain at 100 nm or less throughout one complete cycle of the periodic oscillation.

摘要： A hybrid lens includes a transmissive adaptive liquid lens and an optical element including liquid crystals. The adaptive liquid lens includes a layer of optical fluid on a substrate. A focal length of the adaptive liquid lens is adjustable. The optical element including liquid crystals is optically coupled with the adaptive liquid lens. The optical element including liquid crystals is configured to adjust a refractive index across the optical element including liquid crystals in conjunction with adjusting the focal length of the adaptive liquid lens so that the optical element reduces optical artifacts caused by the adaptive liquid lens.

摘要： Embodiments generally relate to systems and methods for separating an emulsion in a cavity of a device such as a liquid lens device. In one embodiment, the method comprises at least one of: applying a bias voltage to electrodes in the device, causing at least one of droplet migration, flattening of large droplets, and reduced droplet surface tension; applying an oscillating actuation voltage waveform comprising an actuation frequency to the electrodes, such that fluid pumping and turbulence is created within the device cavity; and applying an oscillating excitation voltage waveform comprising an excitation frequency to the electrodes, such that the varying electric field created by the oscillating voltage causes small droplets of the first liquid to coalesce.

摘要： A fluidic lens according to the present invention comprises: a first membrane and a second membrane which face each other; a first means for forming a magnetic field in the first membrane and a second means which exhibits a magnetic force with respect to an external magnetic field formed in the second membrane; a fluid chamber which forms a space between the first membrane and the second membrane and is filled with fluid; and a supplementary chamber connected to the fluid chamber, wherein the second means generates a magnetic force via the magnetic field generated by the first means, thereby causing attraction and repulsion between the first membrane and the second membrane to adjust the focal length of the lens.

摘要： A liquid lens can include a chamber with first and second fluids and an interface between the fluids. A first electrode can be insulated from the fluids, and a second electrode can be in electrical communication with the first fluid. A position of the interface can be based at least in part on a voltage applied between the first and second electrodes. A flexure can be configured to cause a window to displace axially along an optical axis to change a volume of the chamber. The flexure can extend laterally outward from the window substantially linearly, and can be formed between a first recess on an outer side of the liquid lens and a second recess on an inner side of the liquid lens. The second recess can extend laterally outward farther than the first recess such that the first recess and the second recess are offset from each other.
