    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 behaviour of the optical device is reduced, thus yielding an optical device with improved optical characteristics at low temperatures.

    摘要: In an image sensor incorporating a variable focus lens of the electrowetting type, means are provided for reducing or substantially eliminating the occurrence of ghost images. A variable focus lens of the above-mentioned type comprises a housing (5) provided with a first fluid (A) and an axially displaced second fluid (B), the two fluids being non-miscible, in contact over a meniscus (14) and having different indices of refraction. First and second electrodes (2,12) are provided and the shape of the meniscus (14) is controllable in dependence on the application of a voltage between the first and second electrodes (2,12). Various methods of reducing or substantially eliminating the occurrence of ghost images are prepared, including the alteration of the optical properties of an inner and/or outer wall of the housing (5), to reduce the reflectivity thereof, provision of means in the image sensor to intercept ghosting and appropriate selection of the material or combination of materials of which the housing (5) is formed.

    摘要: Motor, comprising a first body (3) and second body (5), the latter being movably mounted with respect to the first body. A chamber (4), sandwiched between surfaces of said bodies, is filled with a non-polar and/or non-conductive first fluid (6) and at least one volume of a polar and/or conductive second fluid (7), which fluids are immiscible. One of said surfaces is provided with means (10) for locally varying the wettability of said surface by the second fluid, to move the or each volume of second fluid along a desired path. The other surface is provided with means (9, 14, 15) for coupling the or each volume of second fluid to this surface, so that this surface will be dragged along by the moving volume or volumes. This results in a relative movement between both surfaces and hence in a movement of the second body.
