In phase-shifting interferometry with unknown phase shifts, a normalization and orthogonalization phase-shifting algorithm (NOPSA) is proposed to achieve phase retrieval. The background of ...

Dynamic thin film interferometry is a technique used to non-invasively characterize the thickness of thin liquid films that are evolving in both space and time. Recovering the underlying thickness ...

Interferometers are research instruments that are utilized in many disciplines of science and technology. Interferometers are so-called because they function by combining multiple sources of light to ...
