Abstract: Projection systems and/or methods comprising a blurring element are disclosed. In one embodiment, a blurring element may comprise a first plate having a pattern on a first surface and second plate. The first plate and the second plate may comprise material having a slight difference in their respective index of refraction. In another embodiment, a blurring element may comprise a first plate having a pattern thereon and a second immersing material. The blurring element may be placed in between two modulators in a dual or multi-modulator projector system. The blurring element may be configured to give a desired shape to the light transmitted from a first modulator to a second modulator.
