摘要： A device (100; 200; 300; 400) comprising a sealed cavity (210) containing n volumes of fluids (80, 87; 220, 230; 320, 332; 420, 422, 430, 432) is described, where n is an integer and n≧2. Each volume of fluid is substantially immiscible with every contiguous volume of fluid. The cavity is defined by an interior surface divided into n continuous areas (60, 170; 260, 270; 360, 362, 370; 460, 462, 470, 472), each continuous area corresponding to and being in contact with a respective one of the volumes of fluid. The wettability of each area is such that each volume of fluid preferentially adheres to the corresponding continuous area rather than any one of the continuous areas adjacent to the corresponding area.

摘要： A variable focus lens comprises a container enclosing an insulating liquid (A) and a conducting liquid (B), the insulating liquid (A) and the conducting liquid (B) being immiscible, having different refractive indices and being in contact with each other via an interface (14), the liquids (A, B) being at least partially placed in a light path through the container. The variable focus lens further comprises an electrode arrangement (2, 12) for controlling the shape of the interface (14) by means of an applied voltage. The container further comprises a transparent end portion (4) in the light path, a part (4) the transparent end portion (4) defining the shape of a part of the interface (14) at a predefined value of the voltage.

摘要： The present invention discloses a method for measuring an intensity of a part of an electromagnetic spectral range, and an electronic device implementing the method. The method comprises the steps of providing an electronic device comprising an optical device (10) comprising at least a first liquid (A) and being placed in front of a sensor (120), the optical device (10) having a transmittance of the part of the electromagnetic spectral range depending on an orientation of at least the first liquid (A); measuring a first intensity of the electromagnetic (EM) spectral range; changing the orientation of at least the first liquid (A); measuring a second intensity of the electromagnetic spectral range; and calculating an intensity of the part of the electromagnetic spectral range from the difference between the first intensity and the second intensity. Consequently, an intensity for a part of the EM spectral range can be measured without the need for a sensor dedicated to this part of the EM spectral range. In particular, an optical element based on the electrowetting principle is used in a mobile phone to measure the intensity of UV radiation.

摘要： An optical scanning device provides a radiation source (2,200), a collimator lens (4,40), an objective (7,90) for converting a beam (5,30′) to a scanning spot at the position of an information layer (101) of a record carrier (1,100). The device also includes an electrowetting cell (6). The electrowetting cell (6) acts such that a beam (5,30′) enters the objective (7,90) at a predetermined height of an entrance pupil of the objective (7,90) independent of the position of the objective (7,90) and that the beam (5,30′) forms a predetermined angle at the entrance pupil of the objective (7,90) with the optical axis (8). In this way the rim intensity may be kept constant over the entrance pupil of the objective (7,90).

摘要： A variable reflector device, comprising a reflector (6) arranged to direct light from a light source (7) and a casing (5) containing the reflector (6), a portion of said casing (5) being transparent to light directed by the reflector (6). The reflector (6) is formed by a meniscus (2) at an interface between two immiscible fluids (3,4) contained in said casing (5). According to this design, the spatial distribution of light from the light source is changeable by changing the shape of the meniscus between the two fluids. Since a change in shape of the meniscus is effected by a displacement of fluids rather than of mechanical parts, the change in reflector shape can generally be performed faster and with less energy consumption than is the case with previously known designs. Further, a meniscus between two immiscible fluids can, due to the nature of fluids, take on several different shapes, which is not the case when a solid body reflector is utilised.

摘要： The electrowetting cel (15) that is primarily to be used as a variable focus lens, comprises a liquid chamber (50) containing a first and a second immiscible fluid (51, 52), which are in contact across a meniscus (14) and of which the first fluid (51) is a polar and the second (52) is electrically conductive. The liquid chamber (50) is provided with an inner face (18), at which a fluid contact layer (10) is present, which has an inherent attraction to the first liquid. An electrode is separated from the liquid chamber (50) through this fluid contact layer (10). The fluid chamber (50) is constructed such that it has a small diameter at an operating point (101) at the inner face (18) than at a point of tangency (102), while a tangent (R1) to the operating point (101) encloses a smaller angle with the optical axis (OA) of the cell (15) than a tangent (R2) to the second point (102). This results in the fact that the meniscus (14) that touches the inner wall (18) at the second point (102) is oriented towards the optical axis and that the cell (15) can have a low construction height.
