Abstract :
An improved RROFDR theoretical model is presented, which simultaneously measure distributed temperature and microbending using a fully distributed optical fiber sensor by optical frequency-domain reflectometry. The relation between the frequency and time is studied, and the model between the v domain and z domain is given. The calculation result is almost consistent with the real one.
