A novel time-domain method is described in which the dynamic phase modulation index applied to an interferometer is directly measured from the waveform of the output photocurrent of the interferometer. A dynamic phase deviation as high as 78 rad has been experimentally demonstrated with a minimum detectable phase deviation of 0.3 rad.
