What are the methods of grating dynamic demodulation
The implementation of signal processing algorithms for fiber optic grating demodulation systems. FJINNO provides various fiber optic grating demodulators with reasonable prices, accurate dynamic demodulation, and universal models. Fiber optic gratings are a new type of passive sensing element with high sensitivity, strong resistance to electromagnetic interference, corrosion مزاحمت, and many other advantages. Since their use in sensing, they have achieved rapid and sustained development, and have broad application prospects in safety monitoring in fields such as aerospace, building structures, and petroleum. The fiber optic grating demodulation system is a key part of the entire sensing system, and achieving high-precision, high-resolution, dynamic and static parameter combination, multi-point multiplexing detection, and low cost is the trend of the development of fiber optic grating demodulation technology. There are various methods for fiber optic demodulation, and the tuned F-P filtering method can only be used to measure static strain. The cost of the tunable laser method is very high, and the non-equilibrium M-Z interference method is easily affected by the environment, which is not conducive to engineering applications. With the rapid development of optical detectors in recent years, miniaturized fiber optic spectrometers have rapidly developed, and fiber optic demodulation technology based on spectral imaging has also developed accordingly. The fiber Bragg grating demodulator based on spectral imaging method has a small volume, high integration degree, and can be used to measure static and dynamic strains. It has outstanding advantages among many demodulation methods and is an important direction of demodulation system research. انهن مان, the optical system performance of the demodulator directly affects the resolution of the system, which is a key aspect of the fiber Bragg grating demodulator.
