A quadrature broadband interferometry system and method obtains a complete complex interferometric signal instantaneously in both homodyne and heterodyne systems in a simple, compact, and inexpensive setup. This is accomplished by separating interferometric components from non-interferometric components in each of at least two detector signals of an interferometer having a number of NxN couplers, scaling the interferometric components, and generating real and imaginary parts of a complex interferometric signal from the scaled interferometric components. The detector signals preferably derive from a broadband light source coupled to the interferometer, and the number of NxN couplers may be one or more, with N >= 3. |
