摘要： Polarization preserving projection screens provide optimum polarization preservation for 3D viewing. The projection screens additionally provide improved light control for enhanced brightness, uniformity, and contrast for both 2D and 3D systems. Generally, the disclosed method for providing a projection screen comprises stripping an optically functional material from a carrier substrate, thus creating engineered particles from the optically functional material. The engineered particles may then be deposited on a second substrate to create a substantially homogeneous optical appearance of the projection screen.

摘要： Polarization preserving projection screens provide optimum polarization preservation for 3D viewing. The projection screens additionally provide improved light control for enhanced brightness, uniformity, and contrast for both 2D and 3D systems. Generally, the disclosed method for providing a projection screen comprises embossing at least a first side of a first substrate to produce an optically functional material and then cutting the optically functional material into pieces to produce a plurality of engineered particles. The plurality of engineered particles may then be deposited on a second substrate to produce a substantially homogeneous optical appearance of the projection screen.

摘要： A flexible optical marker is applied to an optical scale substrate to make an optical scale assembly for an optical position encoder. The marker may be a limit marker, index marker, or other type of marker. The marker substrate may be a plastic film such as polyester, singulated from a “recombine” roll created by a web process. The marker has a microstructured pattern on one surface that is covered with a reflective metal coating. The marker also has an adhesive layer and is affixed to the optical scale substrate by a process of aligning the marker to an edge of the scale and then applying pressure to the upper surface of the marker. The marker may be applied with a handle portion that is separated from the marker after the marker is affixed. The marker may be especially useful with a flexible scale substrate such as a metal tape substrate. By affixing the marker to the scale substrate as a separate step of making an encoder scale, various benefits such as reduced inventory, cost, and lead time may be achieved.

摘要翻译： 将柔性光学标记应用于光学尺度基板以制造用于光学位置编码器的光学尺度组件。 标记可以是限制标记，指数标记或其他类型的标记。 标记基底可以是由通过网状过程产生的“重组”辊形成的塑料膜，例如聚酯。 标记在一个表面上具有被反射金属涂层覆盖的微结构图案。 标记还具有粘合剂层，并通过将标记物与标尺的边缘对准并且然后向标记物的上表面施加压力的方法固定到光学秤基底上。 标记物可以在标记物固定之后施加与标记物分离的手柄部分。 该标记可能对于诸如金属带基材之类的柔性标尺基底特别有用。 通过将标记附着到刻度尺基板上，作为制作编码器刻度的单独步骤，可以实现诸如库存减少，成本和提前期的各种益处。

摘要： Certain embodiments include a method of manufacturing a polymer sheet having surface relief features. In this method, a layer of pre-polymerized material is provided. A plurality of spatially separated locations on the curable material is exposed to ultraviolet light such that the material locally cures at those locations. The curable material is exposed again such that regions outside those locations are also cured. The curing produces the polymer sheet having the surface relief features; the relief features being at those locations.
