High-precision fiber optic liquid level sensor based on fast Fourier amplitude demodulation in a specific range of spectrum
This study presents a fiber optic liquid level sensor (FOLLS) by acquiring information from the amplitude of spectral fast Fourier transform (FFT) in a specified narrow wavelength range. The sensing light path is simply formed by embedding a section of Panda-type polarization-maintaining fiber (PMF)...
