Abstract
A demodulation system for optical fiber Fabry-Perot sensor, including: a light source; a Fabry-Perot sensor; a coupler; a first optical component configured to shape interference light into a linear first interference fringe pattern; a second optical assembly configured to form a second interference fringe pattern; a first detector configured to receive a first light signal to form a first light signal curve; a second detector configured to receive a second light signal to form a second light signal curve; a data collection device configured to receive the first light signal curve from the first detector to generate a first light intensity curve, and receive the second light signal curve from the second detector to generate a second light intensity curve; and a processor configured to calculate a cavity length variation of the Fabry-Perot sensor on the basis of the first light intensity curve and the second light intensity curve.
