Paper Abstract

The extinction ratio of an Electro Optic Modulator (EOM) limits the accuracy of BOTDA measurement of Brillouin-based fiber optic sensors. An EOM with a finite extinction ratio yeilds Brillouin frequency peaks from outside the spatial resolution. This result in confusion in locating the true strain and temperature and error in detecting the Brillouin frequency. The effects of different parameters such as extinction ratio, pulse power and pump power wil be discussed.
