Dual fiber bragg grating strain sensor system |
摘要 |
The present invention provides a dual fiber Bragg grating strain sensor system, which comprises a broadband light source, a power reading unit, and a sensor unit having a first fiber Bragg grating and a second fiber Bragg grating placed adjacent to each other; wherein the broadband light reaches said sensor unit through said power reading unit, the light that corresponds to the intersection between the spectra of the two FBGs is backreflected and is detected by an optical power meter/detector at the detection port.
