PROJECTION SYSTEM MODULATOR REDUCING DISTORTION AND FIELD CURVATURE EFFECTS OF PROJECTION SYSTEM LENS

摘要

A modulator (124) for a projection system includes a surface (253) 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 (451) of the surface matches a field curvature of the lens of the projection system, such that field curvature effects of the lens are reduced.
