| Abstract: | Aiming at that the traditional strength-style optical fiber displacement sensor is installed complex,large drifting,unfit practical application,a new type of fiber Bragg grating displacement sensor is used,a kind of wavelength encoding,self-calibration and not affected by light intensity of novel optical fiber displacement sensing experimental device is designed and implemented.The experimental device simplifies the installation process of traditional strength-style encoding optical fiber sensor and anti-vibration,with temperature compensation function,for quickly mastering the new kind of fiber Bragg grating displacement sensor principle and application of method,and improving optical fiber sensing practical skills with practical significance. |
