Abstract
A highly sensitive fully distributed fiber-optic temperature sensing technique is proposed and demonstrated based on a transient and traveling rocking grating. The rocking grating is generated by pulsed acoustic torsional waves propagating along the fiber. The measured temperature sensitivity is and is experimentally demonstrated mainly due to the temperature dependence of the fiber birefringence. This traveling rocking grating based sensing technique may also serve other fully-distributed sensing applications by using specially designed fibers.
