Abstract

We report a novel method to enhance the performance of Brillouin optical correlation domain analysis system based on the intensity modulation of light source. The suppression and the modification of the background noise in Brillouin gain spectrum is experimentally demonstrated with different intensity modulation schemes. In an optimum configuration, the signal to noise ratio is improved more than 40%, which extends the measurable strain limit and leads to the substantial increase of measurement range.
