    摘要: An optical scanning device (1) for scanning at least one information layer (2) of at least one optical record carrier (3). The device includes a radiation source (7) for providing at least a first radiation beam (4) comprising a first wavelength, an objective lens system (8) for converging the first radiation beam on a respective information layer (2), an information detector (23) for detecting at least a portion of the first radiation beam (22) reflected from the respective information layer, for determining information on said layer, and a spherical aberration detection system. The spherical aberration detection system includes an aberration detector (24) for detecting at least a portion of the reflected first radiation beam for determining spherical aberration of the first radiation beam, and a diffractive element (26) for diffracting at least a portion of the reflected first radiation beam towards the aberration detector (24), and for transmitting at least a portion of the reflected first radiation beam towards the information detector (23). In a first mode of operation the grating is arranged to introduce a phase change to an incident portion of a radiation beam for transmitting that portion towards the information detector (23). In a second mode of operation the grating is arranged to introduce a phase change to an incident portion of the reflected first radiation beam for diffracting that portion towards the aberration detector (24).

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

    摘要: A variable lens (100; 200; 300; 400; 500; 600) is described. The lens (100; 200; 300; 400; 500; 600) comprises a chamber (125) defined by at least one side wall and having an optical axis (90) extending longitudinally through the chamber. The chamber (125) contains a first fluid (130) and a second fluid (140) in contact over a meniscus (150) extending transverse the optical axis (90). The perimeter of the meniscus (150) is constrained by the side walls (125). The fluids (130, 140) are substantially immiscible, and have different indices of refraction. At least one pump (110; 112, 114, 116, 152; 422) is arranged to controllably alter the position of the meniscus (150) along the optical axis (90) by altering the relative volume of each of the fluids (130, 140) contained within the chamber (125).

    摘要: A system for manipulation of a body of fluid, in particular a fluid droplet comprises several control electrodes to which an adjustable voltage is applied to control displacement of the droplet on the basis of the electrowetting effect. There is a counter electrode having a fixed voltage between the body of fluid and one of the control electrodes. Further, as the counter electrode and the control electrodes are located at the same side of the fluid droplet, the fluid droplet is freely accessible at its side remote from the counter electrode and the control electrodes. Hence, the fluid droplet can be employed as an object carrier and a pay-load can be placed on the droplet from the freely accessible side.
