Paper Abstract
Two-wavelength interferometry that is based on a Fourier- transform technique has been investigated. A phase profile at a synthetic wavelength has been obtained by the inverse Fourier transformation of a first-order frequency spectrum for (lambda) 1 wavelength and a minus first-order frequency spectrum for (lambda) 2 wavelength. A power- spectrum of the two-wavelength interferogram can be controlled to eliminate a phase error caused by the difference between modulation intensities at two wavelengths.
