A projection apparatus (10) has an illumination section with a light
source (20) providing a substantially unpolarized illumination beam of
multiple wavelengths. A multiple wavelength polarizer polarizes the
substantially unpolarized illumination beam to provide a substantially
polarized illumination beam of multiple wavelengths. A uniformizer
conditions the substantially polarized illumination beam of multiple
wavelengths to provide a uniformized polarized beam of multiple
wavelengths. A color scrolling element provides a repeating, scrolled
sequence of colors from a set of colors, thereby providing first, second,
and third component wavelength illumination. A component wavelength
modulating section accepts the sequence of first, second, and third
component wavelength illumination from the color scrolling element and
sequentially modulates the first, second, and third component wavelength
illumination at a transmissive liquid crystal modulator panel (118) to
provide a modulated component wavelength beam to a lens for projection
toward a display surface (40).
