Abstract
An optical projection system for use with a display surface includes at least one image source comprising an array of source image pixels, a projector to project a first projection of the array of source image pixels, and at least one mirror including at least one curved reflecting surface having a curved profile. The at least one curved reflecting surface is adapted to convert the first projection to a curved second projection directed onto the display surface to provide an array of displayed image pixels on the display surface corresponding to the array of source image pixels, wherein the array of displayed image pixels have constant pixel pitch among adjacent displayed image pixels.
