摘要:
A spectrum modulation encoding sensor subjected to the physical magnitude to be measured is connected by an optical fiber to a source of incoherent light, and by an optical fiber to a static demodulation system comprising a set of birefringent elements producing a birefringence gradient along a privileged optical direction x; the system demodulates the signal provided by the sensor optically by means of a Fourier transform.
