This article presents an experimental investigation of the characteristics of the module based on the optical tunneling effect, which provides information on the nano displacements resonator of the angular velocity transducer. The analysis of the sensitivity of the module based on the optical tunneling effect with increasing amplitude of forced displacements excited by a piezoelectric module is produced. The principle of operation of the module based on the optical tunneling effect, which is based on the dependence of the reflection coefficient of the radiation source structure "medium-gapmedium" on the size of the gap, is determined. The transfer function of the piezoelectric transducer based on the optical tunneling effect with the total optical losses is determined. The theoretical investigation of the transfer function based on the tunneling effect using the module "optical prism-medium-surface simulator of the edge of the ring resonator" is carried out. The results of the experimental investigation are confirmed that when the amplitudes of the input voltages increase, asymmetric amplitudes of the positive and negative half-waves of the output voltages of the module based on the optical tunneling effect are formed. The scheme of the experimental investigation of the transfer function of the module based on the optical tunneling effect, providing the implementation of optical information retrieval in the measurement of angular velocity, is described. The results of the experimental investigation of the optical information sensing unit at different signals of the wave generator show a good agreement with the theoretical model of the module based on the optical tunneling effect and a small change in sensitivity with increasing the angular velocity and amplitude of the displacement of the resonator edge simulator, which should be compensated for the formation of the output signal.
