Abstract

Experimental results show that an all-fiber temperature sensing system, in which the optical heterodyne detection techniques are used, has the advantage of both high resolution and wide unambiguous measurement range. It is successful in greatly weakening the influence of environment unsteadiness. In the experimental system, due to the use of a polarization maintaining fiber coupler as a beamsplitter, the general beamsplitter and reflecting mirror are saved.
