Experimental test of the nonlinearity of the characteristics of the piezoelectric transducer of the phase modulator of a fiber ring interferometer at small sinusoidal deformations

We show that the level of the second harmonic of sinusoidal modulation resulting from the non-linearity of the characteristics of piezoelectric transducer does not exceed0.005-0.0005% for deformations ranging from10-8 to10-6. The influence of the nonlinearity of the characteristics of a piezoelectri...

Summary:We show that the level of the second harmonic of sinusoidal modulation resulting from the non-linearity of the characteristics of piezoelectric transducer does not exceed0.005-0.0005% for deformations ranging from10-8 to10-6. The influence of the nonlinearity of the characteristics of a piezoelectric transducer used as a modulator of the optical length of the loop of a fiber ring interferometer on the accuracy parameters of the latter is analyzed. It is shown that the given level of the second harmonic does not lead to a significant shift of the zero of the interference of counterpropagating waves at the interferometer output.[PUBLICATION ABSTRACT]
