    摘要: An optical scanning device for scanning an information layer of a first optical record carrier having a first cover layer thickness and an information layer of a second optical record carrier having a second, different cover layer thickness. The device includes an objective lens system for converging a radiation beam on the information layers. The objective lens system includes a first lens element and a second lens element spaced apart along an optical axis. The objective lens system further includes a switchable optical element comprising a first fluid, and a chamber positioned between said first lens and said second lens. The objective lens system is switchable between a first configuration in which the first fluid occupies an optically active portion of the chamber such that the objective lens system has a first focal length for scanning the information layer of the first optical record carrier, and a second configuration in which the first fluid does not occupy the optically active portion of the chamber such that the objective lens system has a second, different focal length for scanning the information layer of the second optical record carrier. The objective lens system is arranged to satisfy the condition: Focal2−Focal1>0.9 (T2−T1)/N, where T1 is the first cover layer thickness, T2 is the second cover layer thickness, T2>T1, N is the refractive index of the second cover layer, Focal 1 is the first focal length, and Focal2 is the second focal length.

    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.
