摘要: A projection screen that includes a multilayer, multiband, single stack device that selectively reflects light with wavelengths in plurality of narrow wavelength bands, and methods for making the screen. The multilayer, multiband, single stack device may be an etalon device. The multiple layers may be deposited on a diffusing substrate. The projection screen may also include a polarizer that coacts with a projector. The projector polarizes the projected light in the narrow wavelength bands into the same polarity and the screen reflects the light with the same polarization and does not reflect light of another polarization. The polarizer may include substrate with a thin polarizing coating. The screen may include a matte surfaced diffuser.

摘要: Methods and apparatus for forming two orthogonally polarized beams of light from an unpolarized beam of light using one of at least two different image modes, the forming includes a color filtering process that is based on the image mode being used, and projecting the two orthogonally polarized beams to form an image on a viewing surface. Methods and apparatus for separating an unpolarized light beam into four beams as a function of wavelength and polarization; selectively modulating the four beams respectively using four light valves; and combining the four modulated beams to generate two orthogonally polarized light beams.

摘要: A method and apparatus that reduces laser speckle by using stimulated Raman scattering in an optical fiber. The pulse repetition frequency of the laser is adjusted to control aspects of the laser light such as color or despeckling. In DLP projection systems, an optical monitor may be used to send information to a bit sequence, and the bit sequence may control the pulse repetition frequency of the laser based on the optical monitor signal.
