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.
摘要翻译：提供了包括具有无色四分之一波片板涂层的折叠镜的光学拾取器。为了使薄膜涂层有效地提供四分之一波长的延迟，光学拾取器被配置为使得入射在折叠反射镜上的光的偏振处于预定角度。根据一个实施例，通过旋转光源来提供预定角度。根据另一实施例，通过旋转包含光源和光束组合器的平面来提供预定角度。在每个实施例中，波束组合器和折叠反射镜沿着相同的轴线布置以进一步提高效率。

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.
