    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.

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: An illumination device (1) for pixelated illumination of a target area (3) comprising: an array (4) of light emitting devices; projection optics (5) arranged in between the array (4) of light emitting devices and the target area (3); a reflecting structure (6) having a first opening (9) facing the array (4) of light emitting devices and a second opening (10) facing the projection optics (5), and a reflective surface connecting the first and second opening, the surface enclosing and facing an optical axis (11) of the projection optics (5). The projection optics (5) is adapted to image the array (4) of light emitting devices, and a virtual extension thereof created by the reflecting structure (6), onto the target area (3), thereby generating an extended pixelated illumination pattern (2). By utilizing a reflecting structure to create a virtual extension of the array of light emitting devices, a high degree of pixelation can be achieved in the illumination pattern while minimizing the number of light emitting devices required. Thus, increased efficiency and reduce costs can be achieved.
