N2 - In this work we have investigated the intensity of ghostlines which occur in the spectrum obtained with a two-beam Fourier interferometer when the travel of its moving mirror is periodically distorted. This intensity has been compared quantitatively with the amplitude of the periodic travel distortion as measured directly with a dilatometer, enabling the determination of travel distortions as small as 0.2 μm. It is concluded that the amplitude of the periodic distortion as calculated from the measured intensity of the ghostlines is in fair agreement with the distortion as obtained from a direct measurement.
