1. A signal processing method, comprising:

  • separating interferometric components from non-interferometric components in each of at least two detector signals of an interferometer having a number of N×

    N couplers;

    scaling the interferometric components; and

    generating real and imaginary parts of a complex interferometric signal from the scaled interferometric components.
