1. An apparatus for optical imaging, comprising:

  • a) an interferometer providing at least one signal;

    b) a spectral separating unit which splits the at least one signal received from the interferometer into a plurality of optical frequencies;

    c) a plurality of detectors, each detector being configured to detect at least a portion of the optical frequencies received from the spectral separating unit; and

    d) an arrangement which is configuredtrack a phase of the signal of the interferometer.
