ABSTRACT:
A fiber optic scanning interferometer in a Michelson arrangement using a polarization splitting coupler is disclosed. The splitting of s and p polarization modes into the fast and slow axes of a birefringent fiber allows the temporal separation of interference phenomena from multiple reflections such that signal recovery is simplified.
