We investigate the distortion of demodulated output signal in a fiber optic Michelson interferometric sensor in relationship to the imperfect properties of its 3 X 3 coupler. A general guide rule in choosing a 3 X 3 coupler and its connection type in the interferometer to reduce this kind of signal distortion is also suggested.
