Abstract
An imaging system () configured to reduce perceived flicker in three-dimensional images is provided. The imaging system () can include a plurality of light sources (), a light combiner (), a light modulator () and a polarization rotator (). The light combiner () combines light received from each of the light sources into a combined beam (). A first light portion () in the combined beam has a first light portion polarization state that is different from a second light portion polarization state of a second light portion (). The light modulator () produces images by modulating the combined beam () along a projection surface (). The polarization rotator () selectively rotates a polarization state of the combined beam () in synchrony with an image refresh cycle of the imaging system. A circular polarizer () can be used to transform linear polarization states to circular polarization states.
