    摘要: The present invention discloses an optical device comprising a container enclosing an insulating liquid (A) and an electrically susceptible liquid (B), the insulating liquid (A) and the electrically susceptible liquid (B) being immiscible and being in contact with each other via an interface (14), at least one of the liquids (A; B) being at least partially placed in a light path through the container. The optical device further comprises heating means (2, 12, 20) that preferably are responsive to a temperature sensor (30) for heating the insulating liquid (A) and the electrically susceptible liquid (B). Consequently, an optical device is obtained in which the influence of the temperature dependence of the physical properties of the insulating liquid (A) and the electrically susceptible liquid (B) on the behavior of the optical device is reduced, thus yielding an optical device with improved optical characteristics at low temperatures.

    摘要: A controllable optical lens system, comprises a chamber housing first and second fluids, the interface between the fluids defining a lens surface. An electrode arrangement controls the shape of the lens surface and has first and second electrodes. A parameter is determined by the system dependent on the electrical resistance through at least one of the lens fluids between the first and second electrodes. Thus, the series resistance through a lens fluid is used as a measure of meniscus position.

    摘要: A controllable electrowetting lens system has a feedback control loop for controlling the electrode arrangement drive signals to implement an autofocus function. The feedback control loop comprising an image analysis focus detection system and a variable gain element. The gain is adjusted based on the lens condition, for example as sensed by a capacitance sensing arrangement. The autofocus control loop can be optimized to the lens characteristics (because the lens characteristics change over time) and/or to external conditions such as temperature.

    摘要: The present invention discloses an electronic device (1) comprising an optical device (10) having a container enclosing an insulating liquid (A) and an electrically susceptible liquid (B), the insulating liquid (A) and the electrically susceptible liquid (B) being immiscible and being in contact with each other via an interface (14), at least one of the liquids (A; B) being at least partially placed in a light path through the container. The electronic device further comprises first signal generating means (34) for generating a control signal indicative of a difference between the actual position of the interface (14) and a desired position; second signal generating means (50) for generating a further control signal for adapting the position of the interface (14) in response to the control signal; and control means (40) for prohibiting the second signal generating means (50) to update the further control signal during a positional change of the interface. Consequently, it is avoided that an update of the further control signal, e.g. a driving voltage of the optical device, is based on a control signal, e.g. a focus error signal, derived from an unstable interface (14).
