Abstract: Light projection systems using white light illumination. One embodiment provides a projection system using white light illumination. The projection system includes an illumination assembly configured to receive a white light input. A prism is configured to separate the white light input into color light inputs, redirect the color light inputs to respective modulators, and combine modulated color light inputs from the respective modulators into a white light output. An optical filter is configured to spatially Fourier transform the white light output to generate a filtered white light output. A projection lens assembly is configured to project the filtered white light output.
