Abstract
The present disclosure provides methods and systems for correcting the shooting of images from a spatial light modulator (SLM) to a substrate, when cross-scan vibrations, including sub-pixel cross-scan vibrations, are present. The methods and systems include shifting a mask pattern on an SLM rotated relative to the in-scan direction of travel on a substrate, shifting along an axis of the SLM to correct for cross-scan vibrations, and either delaying, or accelerating, the shooting of the mask pattern onto the substrate.
