摘要： An optical system and method for providing a visible light beam with a desired characteristic includes a visible light source producing a visible light beam defining an optical train. An optical element is disposed in the optical train to create a modified beam, and that is capable of introducing an undesired characteristic that continuously transitions across at least a portion of the modified beam. A wire-grid polarizer is disposed in the optical train, and has a plurality of elongated elements with at least a portion that continuously transitions to a different characteristic. The wire-grid polarizer is positioned and oriented in the optical train with the different characteristic corresponding to the undesired characteristic of the modified beam to obtain a visible light beam with a desired characteristic substantially across the visible light beam.

摘要： An image projection system has a wire grid polarizing beam splitter which functions as both the polarizer and the analyzer in the system. A light source produces a source light beam directed at the beam splitter which reflects one polarization and transmits the other. A liquid crystal array is disposed in either the reflected or transmitted beam. The array modulates the polarization of the beam, encoding image information thereon, and directs the modulated beam back to the beam splitter. The beam splitter again reflects one polarization and transmits the other so that the encoded image is either reflected or transmitted to a screen. The wire grid polarizing beam splitter is capable of being oriented at various incident angles with respect to the source light beam and modulated beam, and accepts relatively divergent light.

摘要： A display apparatus includes a cube wire-grid polarizing beam splitter with a plate wire-grid polarizer disposed between a pair of prisms secured together to form a cube. A reflective spatial light modulator produces an image bearing color light beam. The cube wire-grid polarizing beam splitter is disposable in the image bearing color light beam to separate the image information and to produce a polarized image bearing color light beam. A pair of continuous film layers is disposed between the plate wire-grid polarizer and a forward prism with a forward layer adjacent the forward prism having a refractive index greater than both i) a refractive index of a rear layer adjacent the plate wire grid polarizer, and ii) a refractive index of the forward prism. A layer of ribs is disposed between the wires and a rear prism, and the ribs being aligned with and supporting the wires.
