摘要：

A multichannel fiber-optic Fabry-Perot (F-P) demodulator based on nonscanning correlation demodulation is proposed. The demodulator principle is analyzed, and the prototype of nonscanning correlation demodulation fiber-optic F-P demodulator is made and tested. The measurement range of the prototype is from 10 to 40 mu m, the demodulation resolution is 8 nm, and its stability is 7 nm. This method provides a feasible solution, which guarantees the practicability of the fiber-optic F-P sensor network.
