description: The given work is devoted to the methods of analysis of incoherent intermode fiber interferometer. The method of correlation processing is presented, which makes it possible to obtain a linear (in amplitude) and stable response to external influences. The relations between the time delays of the modes and the coherent properties of the optical radiation forming the output signal are considered and analyzed. The effective operation of a multimode fiber interferometer when excited by an incoherent broadband source is demonstrated, as well as the elimination of fading and obtaining a stable signal, the shape of which will correspond to the shape of the impact and the amplitude of which will be proportional to the amplitude of the impact. The results of the experiments are in good agreement with the results of the calculations. The results of this work can be useful in the development of fiber sensors of external influences based on the intermode interferometer.
