Abstract (en)
[origin: FR2866443A1] The system has a color wheel (6) with reflective or transmissive color segments to be scrolled on an optic path of a polychromatic light beam so that the segments cut successively a propagation direction of the beam. The color segments are arranged on the wheel in an order such that sum of difference of energy perceived by the observer during the turning of the wheel is minimal. An independent claim is also included for a method of fabrication of a color wheel for a color sequential illumination system of an imager or a spatial light modulator of a projector or overhead projector.
