摘要： Observer tracking is provided in an autostereoscopic 3D display, for instance of the type comprising an LCD panel 2 behind a parallax barrier 3. An infrared sensor such as a position sensitive detector 25 is provided on the LCD panel 2. The parallax barrier 3 extends over the detector 25 so as to form an image of the observer or of a reflective target 22 worn by the observer on the detector 25. The parallax barrier 3 is moved so as to keep the image at a constant position on the detector 25. The viewing zones thus track the observer.

摘要： A spatial light modulator comprises a plurality of picture elements arranged as rows and columns. The columns are arranged as adjacent groups, for instance for association with an element of a parallax device to provide an autostereoscopic 3D display. Adjacent picture elements disclosed in each row and in adjacent columns of each group overlap horizontally so that there are overlapping regions (13) and non-overlapping regions (12). The vertical extent of each picture element is substantially constant throughout the non-overlapping region (12) and is substantially equal to the sum of the heights of the adjacent picture elements throughout the overlapping regions (13). The overlapping regions may be of right-angled triangular shape.

摘要： An eye detection system comprises a source, such as an infrared laser diode 2, for emitting a divergent beam of infrared radiation. A spatial light modulator 4 is controlled so as to act as a deflector for scanning the beam. A detector 7 detects radiation which is retro-reflected by the eye 12 back along the path of the scanning beam. The deflection angle of the SLM 4 and, for a position sensitive detector 7, the location of the centre of illumination on the detector can be used to determine the angle to the centre of the pupil of the eye 12. By subsequently detecting the angle to the glints corresponding to other sources 9 and 10, the gaze position of the eye on a screen 1 can be determined.

摘要： A spatial light modulator or display comprises pixels (10 11 to 10 mn ), for instance arranged as an active matrix. Addressing the pixels (10 11 to 10 mn ) is controlled by shift registers (12, 24) which are configurable so as to vary the effective resolution of the display. Each shift register (12, 24) comprises a plurality of stages (13 1 to 13 m , 23 1 to 23 n ) which are controlled to operate normally or as "followers", in which latter mode the stage output follows the output of the preceding stage.

摘要： A diffractive spatial light modulator comprises first and second substrates (1, 2) between which an optical path is defined comprising, in order, first (8), second (6), and third (8) half wave retarders. The second retarder (6) has a fixed optic axis whereas the first and third retarders (8) have switchable optic axes. The modulator is pixellated and each pixel comprises a switchable phase-only diffraction grating. Each pixel is switchable between a first mode in which incident light is output in the zeroth order diffraction lobe and a second mode in which incident light is deflected into higher order diffraction lobes. The spatial light modulator may be used in high brightness projection displays.

摘要： An illuminator comprises a light guide in the form of a light pipe (12), one surface (12a) of which is provided with a polarization separating layer in the form of an anisotropic layer (16) for separating substantially all of the light of one polarization from the orthogonal polarization component. The anisotropic layer (16) is provided between the light pipe (12) and a reflector (18). The layer (16) has a first refractive index greater than or equal to that of the light pipe (12) and a second refractive index less than that of the light pipe (12).

摘要： A birefringent element (2, 12, 24) is patterned such that for light of a first polarisation the element (2, 12, 24) acts as a first refractive optical element and for light of a second polarisation the optical response of the element (2, 12, 24) changes. The element (2, 12, 24) can be used in conjunction with a polarisation selecting means (22), such as a liquid crystal device, to provide an electrically controllable optical element that can be used in light beam manipulation applications.
