Abstract: 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.

Abstract: A liquid lens can include two or more liquids enclosed in a chamber. The liquid lens can be configured to reduce the chromatic aberration produced when the meniscus formed at the interface of two of the liquids is tilted. This can be accomplished in a number of ways including selecting the liquids to maximize the refractive index difference and minimize the Abbe number difference.

Abstract: A liquid lens system can include a liquid lens and a controller. The liquid lens can include a chamber, first and second fluids contained in the chamber and substantially immiscible to form a fluid interface therebetween, a plurality of insulated electrodes that are insulated from the first and second fluids, and one or more electrodes in electrical communication with the first fluid. A position of the fluid interface can be based at least in part on voltages applied between the plurality of insulated electrodes and the one or more electrodes in electrical communication with the first fluid. The controller can provide voltages to the plurality of insulated electrodes to tilt the fluid interface along a tilt direction, wherein a second average radius of curvature along a direction orthogonal to the tilt direction differs from a first average radius of curvature along the tilt direction by no more than about 20%.

Abstract: In a first aspect, a testing assembly for conducting reliability tests on liquid lenses includes a liquid lens, and a test frame arranged to receive the liquid lens. The liquid lens includes a lens body defining a cavity, a first liquid disposed within the cavity, and a second liquid disposed within the cavity that is substantially immiscible with the first liquid such that an interface between the first liquid and the second liquid forms a lens. The test frame includes a front wall, and a back wall oriented substantially parallel to the front wall. The liquid lens mounts to at least one of the front wall or the back wall and the test frame simulates a smart device incorporating a liquid lens.

Abstract: Control systems for liquid lenses can use feedback control using one or more measured parameters indicative of a position of the fluid interface in the liquid lens. Capacitance between a fluid and an electrode in the liquid lens can vary depending on the position of the fluid interface. Current mirrors can be used for making measurements indicative of the capacitance and/or the fluid interface position. The liquid lens can be calibrated using the measurements indicative of capacitance and/or fluid interface position as the voltage is driven across an operational range. A control system can use pulse width modulation (PWM) for driving a liquid lens, and a carrier frequency for the PWM signals can be varied to control power consumption in the liquid lens. The slew rate can be adjustable to control power consumption in the liquid lens.

Abstract: A liquid lens can tilt a fluid interface, such as for optical image stabilization or off-axis focus. Tilting the interface can cause coma aberration or other dynamic wavefront error. The liquid lens can be driven to reduce the coma aberration or other dynamic wavefront error. For example, input shaped signals can be used. In some cases, the signals can be overdriven and/or underdriven, which can increase response time, and/or encourage settling of the interface.

Abstract: An optical device can include an optical member, positioned at an interface between a first liquid and a second liquid. The optical member can be positionally actuated using the first and second liquid. The optical member may include a plastic lens, a ball lens, a ball lens array, an actuated liquid lens, a biconcave lens, a biconvex lens, a plano-convex, a plano-concave, a negative meniscus lens, a positive meniscus lens, a convex-concave lens, or a concave-convex lens, or any other suitable lens type. The optical member can be actuated in an optical tilt direction, in a left-right horizontal direction, in an up-down vertical direction, in a yaw rotational direction, in an axial direction, or a combination thereof. The optical member can be actuated using electrowetting, using magneto rheological fluids, using static electrofields, using electrical actuation, or using mechanical actuation, for example.

Abstract: A method of separating a portion of an object comprising: presenting an object having a thickness; using a laser emission at a wavelength to perforate at least a portion of the thickness of the object sequentially over a length to form a series of perforations between a first portion of the object on one side of the series of perforations and a second portion of the object on the other side of the series of perforations; and applying a stress to the object at the series of perforations to separate the first portion of the object from the second portion of the object, wherein the thickness of the object, at the series of perforations, is transparent to the wavelength of the laser emission.
