Abstract
The invention concerns a design for generating a multi color image over a projection surface to be applied in digital projectors with reflective LCD chips (LCoS) as image generating elements, in which the light stream, emitted from a white light source, passes over a color modulator, a polarization beam splitter or a color splitter and for the purpose of generating polarized light that divides the light from optical elements in two partial light streams of different polarization planes at the image generating elements and the light portions that serve for generating the images produced by the image generating elements will be reflected in the projection objective. According to the invention, two image generating elements are intended for at least one basic color.
