摘要
An analyzing method for deriving phase information by analyzing a periodic pattern of moiré comprises steps of: subjecting at least a part of the periodic pattern of moiré to a windowed Fourier transform by a window function; calculating analytically, based on the moiré subjected to the windowed Fourier transform, information of a first spectrum carrying the phase information, and information of a second spectrum superimposed on the information of the first spectrum; and separating the information of the first spectrum from the information of the second spectrum, to derive the phase information.
