    摘要: The present invention relates to an autostereoscopic display device, comprising an imaging layer (9) and a lens layer (10). The lens layer (10) serves to project different content from the imaging layer (9) to the left and right eyes, respectively, of a user. The lens layer (10) comprises lens cells (12), enclosing two fluids (13, 14) with different refractive indices. The shape of the interface between the fluids may be changed using electrowetting, by means of two individually controllable electrodes (21, 22) at the sides of each lens cell (12). The display device further comprises a user head tracking device and means for controlling the lens cell electrodes depending on a detected user head position. This allows the display device to display a correct 3D-image, even if the user moves his head.

    摘要: An optical scanning device for scanning an optical record carrier. The optical scanning device includes: a radiation source system (661; 761); an optical element (1; 101; 201; 301) comprising a first fluid (A) and a second fluid (B; C) separated from each other by a fluid meniscus (16; 116, 138; 216; 316) having an adjustable configuration; and a control system (20; 120; 220; 320) arranged to adjust the fluid meniscus configuration to introduce a first type of wavefront modification. The first type of wavefront modification causes the radiation beam to be redirected from an input radiation beam path (2; 102; 244; 348) onto one of a plurality of output radiation beam paths (24, 26; 140; 246; 350) which each have a different angular displacement (α, β, γ, δ, ∈) from the input radiation beam path. The control system is further arranged to adjust the fluid meniscus configuration to introduce a second type of wavefront modification. The second type of wavefront modification is arranged to compensate a wavefront aberration of the radiation beam, the compensated wavefront aberration being adjusted in accordance with the angular displacement.
