A method of phase demodulation of OFDR based on ARC-DSM algorithm
文献摘要：
Aiming at low stability and high harmonic distortion of the traditional phase-generated carrier(PGC)demodulation algorithm,we propose a modified demodulation algorithm for distributed strain sensing in phase-sensitive optical fre-quency domain reflectometry(OFDR).The proposed algorithm combines the arctangent function and differen-tial-self-multiplying(ARC-DSM),which eliminates the effect of modulation depth and realizes the high precision strain variation measurements.Simulation results show that distortion and harmonic distortion are effectively sup-pressed by the ARC-DSM algorithm.The minimum variation of the measurable static strain is about 0.3με and the spatial resolution can reach 0.2 m within 270 m range.
