The light valves provide an image forming light to a projection lens for projecting the image forming light onto a screen. The wheel has front and back surfaces which are displaced from each other and have segments of different colors for separating a polarized white light into the simultaneous different color beams. A retardation film for converting the polarization of colors reflected from the back surface from a first polarization to a second polarization. The wheel is rotated for sequentially illuminating the light valves with different colors of different polarizations simultaneously. The display further includes a polarizing beam splitter assembly for directing the different color light beams from the wheel to the light valves and directing the image forming light to the projection lens. The polarizing beam splitter assembly includes a plurality of polarizing beam splitter sub-assemblies. A clean-up polarizer for absorbing the first or second polarizations is located between two halves of the polarizing beam splitter assembly.

摘要： An apparatus for polarization conversion having a light source for supplying vertically and horizontally linearly polarized light to an optical path and a parabolic mirror disposed in the optical path and proximate to the light source. In different embodiments, the parabolic mirror has a mirror coating to induce a phase shift of 0.degree., 90.degree., or an arbitrary phase shift between incident light and reflected light. A polarizer, preferably a reflective polarizer film, is disposed in the optical path for reflecting light of one of the linear polarizations and for transmitting the other linear polarization. Lastly, one or more waveplates are disposed in the optical path between the polarizer and the parabolic mirror. The waveplates have opposing segments each having axes which are antiparallel to each other for recycling the reflected linear polarization by converting it to the transmitted polarization.

摘要： A lithographic mask is illuminated with light from different directions such that intensities of a plurality of incident beams of light provide a largest possible integrated process window defined in terms of an allowed range for defining shapes. Constrained sets of intensity parameters are imposed. A first set of intensity parameters represents maximum possible intensities that can be permitted for overexposed tolerance positions. A second set of intensity parameters represents minimum possible intensities that can be permitted for underexposed tolerance positions. Optimum source intensities of incident beams are defined using a linear program and constraints. The optimum source intensities maximize an integrated range of dose and focal variations without causing printed shapes to depart from the allowed range. Apparatus are detailed and variations are described.
