摘要：

In this paper a FBG (Fiber Bragg Grating) sensor for measuring temperature and temperature distribution is presented. We have used a phase retrieval algorithm for the temperature measurement. There is presented a method for obtaining the distributed temperature distribution along a fiber Bragg gating by measuring the reflectivity spectrum. We have also a priori knowledge about the complex coupling coefficient's magnitude.
