摘要：
We propose a position determination sensor based on a dual-wavelength Sagnac interferometer. With the wavelength division multiplexing technology, the system has a unique feature of Rayleigh backscatter rejection. The obtained results prove that this new configuration can reduce the scatter noise. The location result is more accurate and the monitoring range is increased.
