ABSTRACT:
A modulator for a projection system includes a surface having a number of pixels defined thereon corresponding to pixels of the projection system. The pixel areas have shapes that counter a distortion of a lens of the projection system, such that distortion effects of the lens are reduced, and/or the side profile of the surface matches a field curvature of the lens of the projection system, such that field curvature effects of the lens are reduced.
