摘要： A beam shaping device (1; 31) comprising first (3; 33) and second (4; 37) optically transparent substrates, a liquid crystal layer (2; 36) sandwiched there between, and first (5; 34) and second (6; 35) electrodes arranged on a side of the liquid crystal layer (2; 36) facing the first substrate (3; 34). The beam shaping device (1; 31) is controllable between beam-shaping states, each permitting passage of light through the beam-shaping device in a direction perpendicular thereto. The beam shaping device (1; 31) is configured in such a way that application of a voltage (V) across the first (5; 34) and second (6; 35) electrodes results in an electric field having a portion essentially parallel to the liquid crystal layer (2; 36) in a segment thereof between neighboring portions of the electrodes (5, 6; 34; 35) and extending substantially from the first substrate (3; 34) to the second (4; 35) substrate. In this way a relatively high refractive index gradient can be obtained across short distances, which enables a very efficient beam shaping. The electric field can be achieved by utilizing electrodes provided on one side of the liquid crystal layer, in a so-called in-plane configuration. The device can be used in an autostereoscopic display device, for switching between 2D and 3D modes.
