Paper Abstract
A simplified BOCDA system for discriminative and distributed measurement of temperature and strain is proposed and demonstrated, in which pump, probe and read light are generated with single laser diode in a time-division way. A linearly-polarized pump and probe light launched in X-polarization axis of a polarization maintaining fiber are used to generate Brillouin dynamic grating, and the orthogonally polarized read light is used to observe Brillouin dynamic grating reflection. We have successfully demonstrated the discriminative and distributed measurement of temperature and strain in the detection along a 70 cm strain applied area.
