Abstract:
1. An image projection system comprising: two sources that each provide electromagnetic (EM) radiation, wherein the sources provide EM radiation in opposing directions; a first reflective surface that reflects EM radiation from the first source a second reflective surface that reflects EM radiation from the second source; an imager that has a pupil for receiving the reflected EM radiation and that uses the received EM radiation to create an image, wherein a first half of the pupil receives reflected EM radiation from the first source, and a second half of the pupil receives reflected EM radiation from the second source, wherein each reflective surface includes a plurality of regions that are flat in at least one direction, wherein a first region of each reflective surface has a smaller angle relative to a line perpendicular to the pupil than does a second region of each reflective surface, and wherein each first region is closer to the pupil than each second region, wherein the plurality of regions is disposed based on an intensity node pattern of at least one of the first or second sources.
