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

摘要： A diffractive liquid crystal device includes a bistable liquid crystal arranged as pixels with each pixel being addressed by a strobe electrode and a pair of interdigitated data electrodes. A strobe generator supplies an initial blanking pulse to each of the strobe electrodes and then supplies strobe pulses in sequence to the strobe electrodes for at least several frames without any more blanking pulses. A data signal generator supplies data signals to the pairs of data electrodes which switch each pixel to a diffractive or non-diffractive state irrespective of its previous state. In particular, the strobe signals comprise pulses of opposite direction in consecutive frames. To select the non-diffractive pixel state, switching signals are applied to both the first and second electrodes during each frame. To select the diffractive pixel state, the first and second electrodes receive non-switching and switching pulses, respectively, during odd frames and switching and non-switching pulses, respectively, during even frames. This arrangement may be periodically reversed for DC compensation.

摘要： A diffractive spatial light modulator includes first and second substrates between which an optical path is defined including, in order, first, second, and third half wave retarders. The second retarder has a fixed optic axis whereas the first and third retarders have switchable optic axes. The modulator is pixellated and each pixel includes a switchable phase-only diffraction grating. Each pixel is switchable between a first mode in which incident light is output in the zero-th 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.
