Abstract

We demonstrated distributed strain measurement using the slope-assisted Brillouin optical correlation-domain analysis (SA-BOCDA) with polarization maintaining fiber (PMF), which has no polarization scrambler. The 0.35- m-long strained section in 47-m-long PMF was clearly measured with 1-kHz sampling ratio and no averaging. Next, we proposed the new concept of the human interactive sound effector using SA-BOCDA with PMF, which means that the distributed measurement data was used as sound waveform directly. Then we demonstrated the sound wave controlling with SA-BOCDA with PMF. This result will be useful for not only the sensing application but also the musical instrument application based on nonlinear optical phenomenon.
