  • Smoothing laser beam integration using optical element motion
    Patent number: 6816316
    Abstract: Embodiments of the present invention provide methods and systems of temporally smoothing the distortion of a light beam caused by imperfections of an optical element or optical system through which the light beam passes. The optical element is moved relative to the light beam to change a position of the imperfections in the path of the light beam to distribute the distortion of the light beam caused by the imperfection without substantially changing the path of the light beam. In some embodiments, the optical element is axially symmetric with respect to its optical axis, and the distortion of the light beam is distributed by rotating the optical element around its optical axis. In some embodiments, the optical element has geometric uniformity relative to a plane or along a line in a plane, and the distortion of the light beam is distributed by moving the optical element along the plane, or along the line of symmetry in the plane.
