An imaging system focuses the electromagnetic radiation at an object plane. A first grating is positioned in the object plane and has a plurality of rulings with randomized height. A stage moves the first grating parallel to the rulings. A projection optical system projects an image of the first grating onto an image plane. A second grating is at the image plane. A detector behind the second grating receives a fringe pattern produced by the second grating.
2. The system of claim 1, wherein said electromagnetic radiation is 13�15 nm.
9. The system of claim 8, wherein said electromagnetic radiation is 13�15 nm.
