In this paper low-coherence fibre-optic sensors based on the Fabry-Perot and Michelson interfero-meter, which were designed and elaborated at our laboratory, are shown. We present results of investigation of the fibre-optic sensors working in both configurations. These results allowed us to compare properties of sensors working in both configurations. The theoretical analysis and experimental results made us possible to select best construction, which was implemented in low-coherence fibre-optic sensors of refractive index.
