摘要： A method and system for use in conjunction with a push-pull liquid crystal modulator system for creating circularly polarized light of alternating handedness is provided. The method and system comprise a pair of surface mode liquid crystal cells and a driver electrically coupled to the cells. The driver is configured to move an electrical charge using a quenching pulse comprising a relatively brief voltage spike at a beginning of a waveform period. Multiple additional improvements are provided, including reducing the thickness of the LC gap (the distance between cell electrode plates), creating a charge connection or wiring connection to the cell electrodes, employing anti-reflection coating technology, thinner ITO and ITO index matched to the LC material, bonding all possible air to material surfaces, using superior glass, employing more efficient polarizers, and reducing projector blanking time.

摘要： A method and system for reducing ghost images in piano-stereoscopic image transmissions is provided. The method comprises establishing a plurality of expected ghosting profiles associated with a plurality of predetermined regions on a screen, and compensating for leakage in each predetermined region of a projected left and right eye images by removing an amount of ghost images leaking from the projected left eye image into the projected right eye image and vice versa. The system comprises a processor configured to receive the quantity of ghost artifacts and compute ghost compensation quantities for left eye images and right eye images. The processor is further configured to remove an amount of actual image ghost artifacts leaking from a projected left eye image into a projected right eye image and vice versa. The processor is also configured to compute ghost compensation quantities for each of a plurality of zones, each zone corresponding to a region on a screen having an expected ghosting profile associated therewith.

摘要： A compound curved projection screen having a curvature about at least one region, such as a cylinder cross section curved about an axis or an ellipse about a plurality of axes, is provided. The compound curved screen comprises a plurality of angled planar reflective surfaces oriented to generally provide light energy in a direction of a screen centered axis. Compound curvature exists by the plurality of angled planar reflective surfaces being positioned in a generally curved and stepped manner about a second region different from the first region, such as a second axis orthogonal to the first axis.

摘要： A multiple path stereoscopic projection system is disclosed. The system comprises a polarizing splitting element configured to receive image light energy and split the image light energy received into a primary path and a secondary path, a reflector in the secondary path, and a polarization modulator or polarization modulator arrangement positioned in the primary path and configured to modulate the primary path of light energy. A polarization modulator may be included within the secondary path, a retarder may be used, and optional devices that may be successfully employed in the system include elements to substantially optically superimpose light energy transmission between paths and cleanup polarizers. The projection system can enhance the brightness of stereoscopic images perceived by a viewer. Static polarizer dual projection implementations free of polarization modulators are also provided.
