摘要： A multi-segment optical retarder that can be used with or within a single projector for creating 3D images. The multi-segment optical retarder is coupled to an actuator used to effect some predetermined linear, rotary, or oscillating movement of the multi-segment optical retarder such that a fast axis orientation of each segment is substantially constant relative to itself over time and for a given area of incidence.

摘要： A method of fabricating an optical element including a liquid crystal layer having a spatially-varying tilt angle includes coating a substrate with a linearly photopolymerizable polymer layer, irradiating the linearly photopolymerizable polymer layer with linearly polarized ultra-violet light at a oblique angle, and coating a layer of liquid crystal material on a surface of the irradiated linearly photopolymerizable polymer layer. The liquid crystal material has a predetermined relationship between its tilt angle and a total dose of the linearly polarized ultra-violet light. The linearly photopolymerizable polymer layer is irradiated with at least one dose of linearly polarized ultra-violet light that is sufficient to induce formation of a plurality of discrete regions within the liquid crystal layer having a larger in-plane birefringence than an adjacent or surrounding region.

摘要： An optical pick-up including a fold mirror having an achromatic quarter-wave plate coating is provided. To allow the thin film coating to efficiently provide the quarter-wave retardation, the optical pick-up is configured such that the polarization of light incident on the fold mirror is at a predetermined angle. According to one embodiment, the predetermined angle is provided by rotating the light sources. According to another embodiment, the predetermined angle is provided by rotating a plane containing the light sources and the beam combiners. In each embodiment, the beam combiners and the fold mirror are arranged along the same axis to further improve efficiency.

摘要： A contrast compensator for improving the panel contrast of liquid crystal (LC) microdisplays having a high-order waveplate configured as an O-plate and supporting a thin film transistor layer is provided. The contrast compensator includes a counter high-order waveplate configured as an O-plate, which has a birefringence opposite in sign to a birefringence of the thin film transistor substrate.
