Abstract

The report defines design features for constructing parallel and sequential reference combined fiber-optic sensors (RCFOS) and constructs their mathematical models with an assessment of sensitivity characteristics for each of the measured parameters, taking into account their mutual relationship by the Edlen equations and the manifestation of the Vernier effect in structures with two Fabry-Perot resonators (FPR). Estimates have shown that such a RCFOS design will allow measuring the ambient temperature in the range of -60…+60 °С with a sensitivity of ~13 pm/°С according to the AFBS, as well as in the range of +10…+60 °С with a sensitivity of ~ -500 pm/°C according to the sequential RFP scheme. In this case, relative humidity (RH) according to the specified RFP scheme can be measured with a sensitivity of ~400 pm/%RH in the range of 20…90%RH, and air pressure according to the parallel RFP scheme ~400 pm/MPa in the range of up to 0.15 MPa.
