Abstract
An imaging system (100) for displaying color images is described. The imaging system (100) comprises an illumination source (102) for generating an illumination beam, an illumination splitting means (106) typically for generating different primary color illumination beams and a plurality of image modulators (104a, 104b, 104c). The illumination splitting means (106) comprises a dynamic selecting means (108) adapted for, for a single color image to be imaged, subsequently generating different sub-sets of primary color sub-beams from said illumination beam and directing these sub-sets of primary color sub-beams to a static selecting means (110). The illumination splitting means (106) also comprises a static selecting means (110) adapted for, for each of said subsequently generated sub-sets of primary color sub-beams, directing primary color sub-beams to said plurality of image modulators (104a, 104b, 104c) for modulating each of said directed primary color sub-beams from said sub-sets for generating said single color image to be imaged. The invention furthermore relates to a controller for synchronization between the image modulators and the dynamic selecting means and to a method for…
