    Method and apparatus for processing the signal in spectral domain interferometry and method and apparatus for spectral domain optical coherence tomography

    Real-time depth measurements in sensing in spectral domain interferometry and for en-face and cross section image production in optical coherence tomography can operate without any need to linearize the data to maximize the output signal and achieve the theoretical depth resolution. Novel interferometry is disclosed, where parameters of a master interferometer dictate the results in a slave interferometer. The master interferometer can be the same measuring interferometer used in two stages. The master interferometer parameters are at least optical path difference (OPD) or the speed of variation of the OPD in the master interferometer. Coherence gated data are produced from ...
