Patent ID: 7334897

Claim:
A projection apparatus comprising: a) an illumination section comprising: i) a light source providing a substantially unpolarized illumination beam of multiple wavelengths; ii) a multiple wavelength polarizer for polarizing and splitting the substantially unpolarized illumination beam to provide a first and second substantially polarized illumination beams of multiple wavelengths; iii) a first and second uniformizer for conditioning the substantially polarized illumination beam of multiple wavelengths to provide a first and second uniformized polarized beam of multiple wavelengths; iv) a first color scrolling element for providing a first repeating, scrolled sequence of colors from a first set of colors, thereby providing a first component wavelength illumination, a second component wavelength illumination, and a third component wavelength illumination from the first multiple wavelength beam; v) a second color scrolling element for providing a second repeating, scrolled sequence of colors from a second set of colors, thereby providing a fourth component wavelength illumination, a fifth component wavelength illumination, and a sixth component wavelength illumination from the second multiple wavelength beam; b) a first component wavelength modulator for accepting the sequence of first, second, and third component wavelength illumination from the first color scrolling element and sequentially modulating the first, second, and third component wavelength illumination to provide a first modulated component wavelength beam to a first lens for projection toward a display surface; and c) a second component wavelength modulator for accepting the sequence of fourth, fifth, and sixth component wavelength illumination from the second color scrolling element and sequentially modulating the fourth, fifth, and sixth component wavelength illumination to provide a second modulated component wavelength beam to a second lens for projection toward the display surface.
