      Methods, systems and computer program products for characterizing structures based on interferometric phase data
      Structure profiles from optical interferometric data can be identified by obtaining a plurality of broadband interferometric optical profiles of a structure as a function of structure depth in an axial direction. Each of the plurality of interferometric optical profiles include a reference signal propagated through a reference path and a sample signal reflected from a sample reflector in the axial direction. An axial position corresponding to at least a portion ...

    2. Methods and systems for reducing complex conjugate ambiguity in interferometric data

      A complex conjugate ambiguity can be resolved in an Optical Coherence Tomography (OCT) interferogram. A reference light signal is propagated along a reference path. A sample light signal is impinged on a sample reflector. The reference light signal is frequency shifted with respect to the sample light signal to thereby separate a positive and a negative displacement of a complex conjugate component of the OCT interferogram.

    3. System and method for low coherence broadband quadrature interferometry

      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 N.times.N couplers, scaling the interferometric components, and generating real and imaginary parts of a complex interferometric ...
