摘要

A frequency modulation demodulator based on fiber grating sensor array comprises: a laser, radio frequency signal source, acousto-optic modulator, delay fiber pair, Mach-Zehnder modulator, optical filter, optical amplifier, optical isolator, circulator, fiber grating sensor array, photodetector and data acquisition card. By the cooperation of delay fiber pair and the fiber grating, the reflected optical pulses of the two gratings (the front grating and the back grating) are overlapped in the time domain to form interference, and thereby achieving multi-point array interference demodulation.
