发明名称 CYCLIC ERROR REDUCTION IN AVERAGE INTERFEROMETRIC POSITION MEASUREMENTS
摘要 An initial interferometric position measurement of the stage (120) is averaged with at least one additional measurement corresponding to a displacement of the stage from its initial position. The displacements are selected to reduce the overall cyclic error contribution to an average position measurement.
