- 초록
- We propose and experimentally demonstrate a novel fiber sensor array based on Sagnac interferometer with very simple electronic signal processing. A stable quadrature phase bias was obtained using a phase modulator, and polarization-induced signal fading was suppressed by using a depolarizer and a broad-band source. Phase sensitivity of about 4.0 μradrms/?닖Hz at 5 kHz was obtained using a two-sensor array.
