<p>The invention relates to a projection system comprising: a polychromatic light source and at least one imaging assembly illuminated by an associated polychromatic illumination beam, and comprising: two separate colored wheels, respectively called first and second colored wheel; and three separate imagers, respectively called first, second and third imagers. At least one part of the polychromatic beam, called first source beam, illuminating the first colored wheel which separates said source beam into a first monochromatic beam and into a two-tone beam, said first monochromatic beam illuminating the first imager and said two-tone beam being transmitted toward the second colored wheel. The second colored wheel being illuminated by said two-tone beam and separating said two-tone beam into second and third monochromatic beams, respectively illuminating said second and third imagers respectively.</p> |
