摘要： A method includes generating a plurality of beams that each illuminate a separate portion of a spatial light modulator. The spatial light modulator has a first dimension of a first length and a second dimension of a second length. Each of the beams spans a portion of the first length of the first dimension and a portion of the second length of the second dimension. The method also includes scrolling the plurality of beams along the second dimension of the spatial light modulator while maintaining at least a first gap between each of the plurality of beams.

摘要： A digital keystone correction process locates image points in a corrected image from image points in a distorted image that was produced by misalignment of the axis of a sensor such as a camera. The correction process locates corrected image points by constructing intercept points that are the intersections of the extended sides of a quadrilateral in the distorted image plane that is constructed from a known rectangular feature in the subject plane. Reference points are located by drawing a line through each intercept point and the distorted image point. Distances are found from the intercept points to the image points and the reference points. The distances are scaled and corrected with an offset to locate the coordinates of the image points in the corrected image plane. This process can correct alignment errors of pitch, yaw, and roll between the subject plane and an image plane such as photographic film.
