A novel white-light interferometry capable of retrieving the absolute optical path difference is presented, in which a 3 × 3 coupler-based interferometer is employed. The measured phase change is in agreement with that obtained by Fourier transform white-light interferometry. The linear property is also experimentally demonstrated.
