Abstract

A method and an arrangement for characterizing in-fiber gratings are disclosed. According to the invention, the characteristics of a fiber grating are analyzed by reflecting light in a measurement branch of an interferometer from the grating, and subsequently interfering the reflected light with light from a reference branch of the interferometer. A first measurement value is recorded. Then, the polarization state of the light in the reference branch is switched to an orthogonal state, whereupon a second measurement value is recorded. A polarization insensitive interference value is obtained by taking the quadratic sum of the first and the second measurement values.
