  • Method and apparatus for full phase interferometry
    Publication number: 20060290939
    Abstract: An apparatus and method for differential spectral interferometry comprising providing an interferometer comprising a light source; employing an element to provide a dithered relative phase shift between target and reference arms of the interferometer, detecting output from the interferometer, demodulating signals received from the detector at different multiples of the dither frequencies, generating more than one real-valued interferograms from demodulated signals, and using the real-valued interferograms to obtain the complex spectral interferogram.
