1. An optical coherence analysis system, comprising:

  • a swept source including a tunable filter for spectrally filtering light from a broadband source, which generates a broadband optical signal, to generate a tunable optical signal that is spectrally tuned over a scanband and an optical amplifier for amplifying the tunable optical signal with the amplified tunable optical signal being returned to be again filtered by the tunable filter while preventing lasing and formation of a resonator; and

    an interferometer for dividing the amplified tunable optical signal between a reference arm and a sample arm and generating an interference signal by combining the optical signal from the reference arm and the sample arm; and

    a detector system for detecting the interference signal.
