摘要 |
A magnetic flux sensor is disclosed. The sensor comprises an optical fiber and at least one twin-grating structure formed on the optical fiber. Each twin-grating structure comprises a first optical grating structure, a second optical grating structure adjacent the first optical grating structure, and a sensing cavity disposed between the first and second optical grating structures. Each twin-grating structure is selectively responsive to a unique wavelength of light to generate an optical interference fringe signal. The sensor also includes a magnetostrictive coating disposed over each twin-grating structure to change an optical property of the twin-grating structure and a phase of the optical interference fringe signal when the magnetostrictive coating is exposed to changing magnetic flux. |
