摘要：<p>Sensor for measuring the temperature generated by an optical fiber with a liquid coating for the buffer based on the measurement wavelength lambda0 the interfering modes LP01 and LP02 or leveling measurement wavelength lambda0 interfering the LP01 and LP11 modes depending on the temperature. The basis of the proposed sensor is 5 cm long optical fiber sensor fused silica core with a diameter of 10 microns, which forms a sheath chloroform. Different temperature coefficients of the refractive index for fused silica and chloroform cause significant changes in the buffer wavelength lambda0 for interfering modes LP01 and LP02 or for interfering modes LP11 and LP01, depending on the temperature. Value Buffer wavelength lambda0 for interfering modes LP01 and LP02 and LP01 modes for interfering and LP11 is used directly to determine the temperature.</p>
