Abstract
A method for determining an optimum gain response in a spatial frequency correction for a projection system comprises the steps of setting a code value () to a first code value; projecting a flat field image at the code value; capturing the flat field image () with a camera; creating a defect map () of defects in the flat field image; applying the defect map to the flat field image to form a corrected image; setting a gain table () to a first gain for the corrected image; applying the gain table to the corrected image; registering the corrected image; filtering the registered image; measuring the filtered image for a standard deviation (); determining whether all gains for producing an under corrected image () and an over corrected image have been exhausted for the code value; if all gains have not been exhausted for the code value, set the gain table to the first gain plus n and go to the step of applying the gain table to the corrected image, if all gains have been exhausted go to determining an optimum gain for the code value.
