20110249226 | SELF-COMPENSATING, QUASI-HOMEOTROPIC LIQUID CRYSTAL DEVICE WITH HIGH CONTRAST RATIO - Self-compensating, quasi-homeotropic liquid crystal devices overcome the contrast reducing effects of smaller pretilt angles. The devices exhibit extremely high contrast ratio but at the same time suppress fringe field-induced disclination lines in high pixel density and small pixel size quasi-homeotropic displays. The surface pretilt and cell twist angles are set at values that, in combination, contribute to establishing a cuspate singularity in the contrast ratio for normally incident light in response to a drive signal switching the liquid crystal device to the OFF director field state that provides nearly 0% optical efficiency. The OFF director field state corresponds to a subthreshold drive level that provides for the liquid crystal device self-compensation for in-plane optical retardation. Setting the cell gap (“d”) to provide substantially 100% optical efficiency in response to a value of the drive signal switching the liquid crystal device to the ON director field state achieves optimal dynamic range for the liquid crystal device. | 10-13-2011 |
20120044431 | HIGH-SPEED LIQUID CRYSTAL POLARIZATION MODULATOR - A polarization modulator for time-multiplexed stereoscopic 3D applications rapidly switches between two polarization states in alternate subframes. The polarization modulator uses two liquid crystal devices arranged in optical series and driven such that the second device compensates a change the first device makes to an input polarization state of incident light during alternate subframes. The compensating liquid crystal devices are characterized in that, if the same voltage is applied to both of them, the second device compensates the change that the first device makes to the input polarization state, regardless of the applied voltage level. If the applied voltage is changed from one level to another and the liquid crystal material in the liquid crystal devices relaxes to the new voltage level, polarization state compensation will take place throughout the duration of the relaxation so that the slow, unpowered transition does not manifest itself as a change in polarization state. | 02-23-2012 |
20120147280 | OPTICAL POLARIZATION STATE MODULATOR ASSEMBLY FOR USE IN STEREOSCOPIC THREE-DIMENSIONAL IMAGE PROJECTION SYSTEM - An optical polarization state modulator assembly for use in a stereoscopic three-dimensional image projection system includes a spatial light modulator, a light source emitting multiple wavelength components of light for incidence on the spatial light modulator, and a projection lens. A polarization converter system cooperates with the spatial light modulator to produce in alternating sequence polarized light carrying first and second perspective view images of a scene in different ones of first and second subframes. A polarization modulator, in response to first and second drive signals, imparts to, respectively, the image-carrying polarized light a first output polarization state during the first subframe and to the image-carrying polarized light a second output polarization state during the second subframe. The image-carrying polarized light in the first and second output polarization states propagates through the projection lens for transmission to an observer. | 06-14-2012 |
20140327837 | ENHANCED VISION SYSTEM IMPLEMENTED WITH OPTICAL SHUTTER ALTERNATELY TRANSMITTING VISIBLE RADIATION AND NEAR INFRARED RADIATION - An optical shutter employed in an enhanced vision system includes a wavelength selective polarizing filter in optical association with a liquid crystal polarization modulator to rapidly switch between optical states to alternately transmit visible (VIS) radiation and near infrared (NIR) radiation. The wavelength selective polarizing filter imparts a polarization state to incident radiation and transmits polarized radiation within at least the visible wavelength region. The liquid crystal polarization modulator receives incident radiation for internal propagation through the modulator and responds to first and second values of an applied control signal to switch the internally propagating radiation to, respectively, first and second polarization states. The switching between first and second polarization states produces, in cooperation with the wavelength selective polarizing filter, optical shutter output VIS and NIR radiation. A computer processes the output VIS and NIR radiation to produce for display a composite image formed of visible and infrared elements. | 11-06-2014 |
