Abstract
Projection system comprising at least two light sources, a projection lens and a spatial light modulator located between the light sources and the projection lens, which light modulator comprises a plurality of light-deflection devices each provided with an element which is tiltable about a tilt axis. The light sources are arranged with respect to the spatial light modulator in such a way that, in operation, the centers of the light beams coming from the light sources and projected on each element are located on a projection line which extends substantially parallel to the tilt axis of the element.
