Abstract
A new demodulation method is proposed for application of fiber optic interferometric system in high sensitivity and large dynamic range. On the basis of the structure and principle of the system, a phase demodulation algorithm is proposed to determine the disturbances. The signal demodulation technology is realized by software. The results show the demodulated signals are the same as the disturbing signals.
