Abstract: Coherence length is one of the key factors to determine the measurement resolution in white light interferometry. By the use of multi-wavelength combination source, the equivalent coherence length can be greatly reduced. In this work, the multi-wavelength combination source together with the fringe pattern transform technique is used to further reduce the equivalent coherence length and achieve a stable, high precision white light interferometric measurement.
