Abstract
According to one embodiment of the present invention a method for directing light onto a digital micromirror device is disclosed that includes the steps of directing light toward a DMD through a lens that includes a plurality of lens elements such that, absent correction, the directed light is distorted at the DMD; and compensating for the distortion of the directed light at the DMD by predistorting the directed light prior to reaching the DMD by the plurality of lens elements.
