Abstract

An all-fiber 3× 3 coupler based phase-shifted white-light interferometry is presented, with which the absolute optical path difference (OPD) of a MachZehnder interferometer can be measured automatically. The continuous test shows that the variation is ±0.5μm when measuring a beam length of ∼10 m with an OPD of 1847 μm. The technique is successfully demonstrated to measure static measurands, including strain, temperature and weight.
