Patent ID: 8622551

Claim:
An image projection system comprising: a first source that provides electromagnetic (EM) radiation traveling in a first direction along an optical axis of the first source; a second source that provides EM radiation traveling in a second direction along the optical axis, the second direction being anti-parallel to the first direction; a first reflective surface that reflects EM radiation from the first source; a second reflective surface that reflects EM radiation from the second source; and 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.
