A projection system that includes a singe light modulation device and a plurality of light sources of different wavelengths. Each wavelength of light is incident on the light modulation device at a spatially distinct location and a temporally distinct time. The use of a scanning mirror allows the projection system to sequentially form, in full-color, each of the columns or rows of an image. The projection system is characterized by the reduction of color separation or the rainbow effect due to the rendering of each column or row in full color.
The invention claimed is: 1. A projection system for generating an image on a surface, the projection system comprising:a light modulation device;a plurality of light sources, each of the plurality of light sources emitting a different wavelength of light that is imaged on the light modulation devic
The invention claimed is: 1. A projection system for generating an image on a surface, the projection system comprising:a light modulation device;a plurality of light sources, each of the plurality of light sources emitting a different wavelength of light that is imaged on the light modulation device as a column of light having a height, a width, and a centerline bisecting the column of light along its height;an input optical assembly interposed between said light modulation device and the plurality of light sources; andwherein each of centerlines of the columns of light is centered on the light modulation device at a spatially distinct location with respect to the centerlines of the other columns of light;wherein a spacing between adjacent centerlines of columns of light on the light modulation device is at least 1.5 microns;wherein each column of light has a substantially uniform distribution along its height and a non-uniform distribution along its width.
