1. A method for determining, in-situ, linear modulator dynamics in an interferometric fiber-optic gyroscope, comprising:

  • applying a first signal to a phase modulator located within an interferometric fiber-optic gyroscope;

    observing a response in an output of the interferometric fiber-optic gyroscope to the first signal; and

    determining, from the observed response, linear modulator dynamics introduced by the phase modulator,wherein determining the linear modulator dynamics comprises determining at least one of (i) one pole or (ii) one zero of the phase modulator.
