Abstract:

The output characteristic of a polarized optic fiber sensor under the external influence of bending and stretching is discussed using the means of light′s transfer equation and characteristic of modes coupling in optic fibers, and some experiments are done. The polarized optic fiber sensors have been used in smart composite structures, and the location of loading on the structure has been detected successfully.
