    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.
