Significats de demodulation en anglès

A new type of demodulation system for low-coherence interferometric sensors based on highly birefringent fibers is presented.

Harmonic demodulation of the fluorescence signal produced by a modulated excitation light extracts the nonlinear fluorescence signals.

Other circuitry elements, such as loop controlling and accurate demodulation modules, are all implemented in digital logics.

That is, the MZI-based sensor overcomes the cross-sensitivity problem between tensile strain and temperature by means of different demodulation methods.

A fiber-optic polarimetric strain sensor of l(S)=10-cm sensing length with three-wavelength passive quadrature digital phase demodulation is investigated.
