    摘要: A polarizer is formed with an arrangement of polymer fibers substantially parallel within a polymer matrix. The polymer fibers are formed of at least first and second polymer materials. At least one of the polymer matrix and the first and second polymer materials is birefringent, and provides a birefringent interface with the adjacent material. Light is reflected and/or scattered at the birefringent interfaces with sensitivity to the polarization of the light. In some embodiments, the polymer fibers are formed as composite fibers, having a plurality of scattering polymer fibers disposed within a filler to form the composite fiber. In other embodiments, the polymer fiber is a multilayered polymer fiber. The polymer fibers may be arranged within the polymer matrix as part of a fiber weave.

    摘要: A dispersing element for a rear projection screen assembly is sensitive to the polarization of the light passing through the element. In particular, the element disperses light having a first polarization differently from light having a second polarization orthogonal to the first polarization. The dispersing element may be aligned with a polarization axis neither parallel nor perpendicular to the polarization of the light passing through the element. The dispersing element may also be employed with a polarizer to remove unwanted light that propagates through the dispersing element. The dispersing element may also be rotatably mounted relative to a polarized light source so as to vary the angle between the polarization axis of the element and the polarization direction of the light.

    摘要: The present invention provides light valves including polarizing elements in which light transmission can be controlled by rotating at least one of the polarizing elements about an in-plane axis. Although reflective polarizing elements are preferred in devices according to the present invention to reduce the problem of heat build-up, the use of absorptive or other polarizers may also be envisioned. The polarizing elements may also include at least one reflective polarizer in combination with an infrared reflective material or an infrared absorptive material. The polarizing elements can be included in light valves to control light transmission by rotating at least one of the polarizing elements about an in-plane axis. The light valves according to the present invention may find use in any application in which the transmission of light (visible or otherwise) is to be controlled. Examples of specific applications include, but are not limited to: windows, luminaires, skylights, etc.
