Patent number: 6373549Abstract: A diffractive spatial light modulator comprises first and second substrates (1, 2) between which an optical path is defined comprising, in order, first (8a,8b), second (5,6), and third (8a,8b) half wave retarders. The second retarder (6,5) has a fixed optic axis (9c) whereas the first and third retarders have switchable optic axes (9a,9b). The fixed optic axis (9c) is oriented outside the switching ranges of the switchable optic axes (9a,9b). 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.Type: GrantFiled: January 21, 2000Date of Patent: April 16, 2002Assignee: Sharp Kabushiki KaishaInventors: Craig Tombling, Michael Geraint Robinson, Nicholas Mayhew, Tomoaki Kuratate

Patent number: 6104368Abstract: 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.Type: GrantFiled: March 31, 1998Date of Patent: August 15, 2000Assignee: Sharp Kabushiki KaishaInventors: Paul Bonnett, Nicholas Mayhew, Michael Geraint Robinson, Craig Tombling, Michael John Towler

Patent number: 5861940Abstract: 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.Type: GrantFiled: July 30, 1997Date of Patent: January 19, 1999Assignee: Sharp Kabushiki KaishaInventors: Michael Geraint Robinson, Craig Tombling, Nicholas Mayhew, Robert George Watling Brown
