摘要： A switchable optical element is described, along with a method of manufacturing such an element. The switchable optical element (1) comprises a fluid chamber (2) including immiscible first and second bodies of fluid (20, 22) disposed relative to one another along an optical axis (A) of the element (1). The second body of fluid (22) is movable in a direction away from the optical axis (A) by electro-wetting action, giving the switchable optical element (1) a changeable transmissivity along the optical axis (A). The switchable optical element (1) is suitable for use as an optical attenuator, e.g. a shutter, filter or diaphragm, and can be conveniently used in place of mechanical alternatives in applications such as cameras, laser resonant cavities, projectors and devices for scanning optical record carriers.

摘要： The invention relates to an electrowetting-on-dielectric device (200). This is an electro wetting device comprising one or more cells, wherein each cell comprises an electrowetting composition of first and second immiscible fluids, the first fluid being an electrolytic solution (240), a first electrode (230), separated from the electrowetting composition by a dielectric (231), and a voltage source (260) for applying an operating voltage difference between the first electrode (230) and the electrolytic solution to operate the electrowetting device. According to the invention, the first electrode (230) of the electrowetting-on-dielectric device (200) comprises a valve metal, and the electrolytic solution (240) is capable of anodizing the valve metal to form a metal oxide at the operating voltage difference. This provides the electrowetting-on-dielectric device (200) with self-repairing properties thereby preventing breakdown of the dielectric. As a result, the electrowetting device can be operated at a low voltage, and it has an improved reliability.

摘要： An adjustable fluid type lens system is provided that allows e.g. ultrasound imaging through the lens during adjustment of the lens. The lens includes a container enclosing two immiscible fluids, e.g. water and oil, being in contact with each other at an interface. Incoming waves are then refracted at this interface. The shape of the interface, and thereby the refraction property, is adjustable by adjusting a voltage applied to the lens. The two fluids are selected such that they together exhibit a mechanical damping which is critical or near critical. A control circuit generates the electric voltage for adjusting the refraction from one value to another, the control circuit being arranged to change the electric voltage such that a rate of voltage change is limited to avoid oscillation of the interface, thereby adjusting refraction of incoming waves at the interface in a continuous manner. This makes it possible to use the lens while it is during adjustment from one refraction value to another, since the interface shape will at all time during the adjustment have a controlled shape. The voltage can be either a continuous voltage or a discrete stepwise (digital) voltage which is just controlled with respect to step size and temporal extension of the steps. The lens system has a number of applications e.g. within the medical field, e.g. for ‘on the fly’ high speed ultrasound imaging, or for ultrasound ablation applications where ablation can be performed during adjustment of the lens to follow a pre-defined trajectory.

摘要： Apparatus for providing a fluid meniscus with variable configurations by means of electrowetting. A fluid chamber (5) holds two different fluids (A, B) separated by a meniscus (14) of which the edge, having different sides, is constrained by the fluid chamber. A first electrowetting electrode (2a) is arranged to act on a first side of the meniscus edge and a second electrowetting electrode (2a′) is arranged to act separately on a second side of the meniscus edge.

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.
