Abstract:
1. An illumination system, comprising: a deformable micromirror device operable to direct an image to a projection lens; a light emitting diode operable to generate a light beam having a substantially circular cross section for use in illuminating the deformable micromirror device; and an assembly of at least two optical elements coupled between the light emitting diode and the deformable micromirror device, the assembly comprising first and second optical elements spatially separated by a gap such that an exit surface of the first optical element and an entry surface of the second optical element form a non-zero angle, wherein the assembly is operable to anamorphically modify the light beam passing through the first optical element and the second optical element to the deformable micromirror device.
