Abstract

White light interferometry (WLI) has been proved as a successful technique to improve the unambiguous range of a conventional interferometric system and to make absolute measurements. In WLI operation, the central fringe position in the output fringe pattern has crucial importance as a knowledge of such a position provides a reliable basic reference.
