Abstract: A liquid lens can be coupled to ground, such as to impede charge from building up in the liquid lens during operation thereof. For example, an electrode that is in electrical communication with a conductive fluid of the liquid lens can be coupled to ground. A switch can be used to selectively couple the liquid lens to ground, such as for discharging the liquid lens. An electrode can be selectively coupled to ground and to driving signals using a switch. In some cases, drive signals can be provided to electrodes other than the grounded electrode for driving the liquid lens. In some cases, the liquid lens can be driven using feedback control based on one or more measured parameters indicative capacitance between a fluid and one or more electrodes in the liquid lens.

Abstract: A variable focus lens system can include a variable focus lens, one or more electrodes, a signal generator configured to supply voltage to the one or more electrodes to vary the focal length of the variable focus lens, and a controller configured to apply a voltage to the one or more electrodes and receive information indicative of a capacitance that results from the applied voltage. The controller can be configured to determine a temperature of the variable focus lens based at least in part on the capacitance or applied voltage. The variable focus lens system can include a temperature sensor, and the controller can be configured to receive temperature information from the temperature sensor and calibrate the temperature sensor based at least in part on the received temperature information, the applied voltage, and the received capacitance information.

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 include a first substrate with an interior recess. A second substrate with a bore can be bonded to the first substrate, whereby the interior recess of the first substrate and the bore of the second substrate cooperatively define at least a portion of a cavity of the liquid lens. A first liquid and a second liquid can be disposed in the cavity. A variable interface can be disposed between the first liquid and the second liquid, thereby forming a variable lens. The interior recess of the first substrate can be positioned outside of a sidewall projection of a sidewall surface of the cavity through the first substrate.
