Abstract
An optical projection system which creates pincushion distortion of an image and then creates a barrel distortion of the pincushion-distorted image to compensate for the pincushion distortion and then projects an enlarged image without substantial distortion onto an image display surface. An embodiment includes a polynomial reflector to compensate for the pincushion distortion, to enlarge an image, and to project the enlarged image toward a screen.
