| Abstract: | A fiber Bragg gratings vibration acceleration measurement system was designed by using the tunable Fabry Perot filter technology.A temperature compensated fiber Bragg gratings acceleration sensing probe was proposed in this work.The elastic system of the sensing probe was composed of an inertial mass block,dual spring and steel pipe.The fiber Bragg grating free of strain was used to compensate the temperature of probe.The proposed sensing probe has the advantages of simple structure,being free from the electromagnetic interference,optical path power fluctuation and phase noise,and being realized temperature compensation automatically. |
