    Abstract: A phase stepping method for determining an aberration map for a projection system and an apparatus for carrying out said method. The method uses first patterned region arranged in an object plane of the projection system and a second patterned region arranged in an image plane of the projection system. At least one of the first and second patterning regions is moved in a shearing direction to generate an oscillating phase stepping signal. A set of coefficients that characterize the aberration map of the projection system are determined by equating the phase of a harmonic of the oscillating signal at each of the plurality of positions on the radiation detector to a combination of a plurality of differences in the aberration map between a pair of positions in a pupil plane of the projection system and solving to find the set of coefficients.
