title = "Fourier transform-based absolute phase interrogation algorithm for Sagnac Interferometer-based PMF Sensors",
abstract = "A high resolution and absolute phase interrogation algorithm for Sagnac interferometer based polarization maintaining fiber (PMF) sensor is proposed. Taking wavenumber instead of wavelength as the function variable, the output spectrum will be a standard cosine spectrum function. After Fourier transform, the frequency and relative phase of this spectrum function can be obtained and the precise absolute phase due to optical path difference between the two polarization modes in sensing PMF can be determined. A typical Sagnac interferometer based PMF temperature sensor was built and the absolute phase was determined by use of the proposed algorithm. Experiments show that 0.1oC temperature resolution and up to 900 oC temperature can be measured with good linearity.",
