Having discribed the measurable slope of Fourier transform profilometry(FTP)and improved FTP(IFTP)
a modified FTP(MFTP)for the measurement of 3-D steep shapes is proposed in this paer.The detail measuring method and theory analysis ars also given. The artificial error introduced in IFTP was eliminated by utilizing the merits of FTP.
