| titleOfInvention | Fiber optic temperature based on high spectral resolution technology and stress sensing device and method |
| abstract | The invention discloses the invention provides a kind of fiber optic temperature based on high spectral resolution technology and stress sensing device, including optical emission system, optical fiber sensing system, high spectral resolution scanning system, optical filter system, data collecting system and control system.The invention also discloses a kind of fiber optic temperature based on high spectral resolution technology and stress sensing method.The present invention scatters carrier wave, distributed sensing temperature and the strain as temperature and strain based on optical fiber Brillouin；Leach optical fiber Brillouin back scattering using narrowband reflection formula tunable Bragg grating, using chamber length tunable Fabry Perot interferometer, full spectral scan is carried out to optical fiber Brillouin scattering spectra, using backward Brillouin scattering signal in single photon technique detection optical fiber；Its structure is simple, good stability, compared to coherent detection, reduces signal detection and the difficulty processing and complexity, improves range resolution ratio and the precision of detection. |
