PROBLEM TO BE SOLVED: To provide a stripe image analytical method for extracting substantially only a desired spectrum including phase information, and thereby carrying out analysis reduced in errors. SOLUTION: This stripe image analytical method extracts the phase information, from a stripe image superposed with a carrier stripe. The method includes processes of: Fourier-transforming the stripe image to find all the spectra; subtracting other spectra excepting the desired spectrum, from all the spectra, to extract the desired spectrum; and inverse-Fourier-transforming the extracted desired spectrum to obtain the phase information.
