A display device including an optical display element and a polymer face plate that receives or directs light to the optical display element. The face plate includes columnar areas where an index of refraction of the columnar areas is different from the index of refraction of a cladding area surrounding the columnar areas. The columnar areas are formed by exposure of a photoactive resin to a light interference pattern formed by three collimated and coherent light sources.

摘要： A polarization grating comprising a polarization sensitive photo-alignment layer (2) and a liquid crystal composition (3) arranged on said photo-alignment layer is provided. An alignment pattern, corresponding to the polarization pattern of a hologram, is recorded in the photo-alignment layer, and the liquid crystal composition is aligned on the photo-alignment layer. As the origin for the alignment of the liquid crystal composition is a polarization hologram recorded in a photo-alignment layer, an essentially defect-free pattern can be obtained with this approach.

摘要： Polarization based channeled images are optically demodulated to produce directly viewable images. A channeled image flux is converted to an unpolarized flux by a phosphor or other sensor, and the resulting converted flux is demodulated by modulating at a spatial frequency corresponding to a modulating frequency of the channeled image flux. After modulation, the converted flux is spatially filtered to remove or attenuate portions associated with the modulation frequency and harmonics thereof. The resulting baseband flux is then imaged by direct viewing, projection, or using an image sensor and a display.
