SINGLE MODE FIBER BRAGG GRATING PRESSURE SENSOR |
摘要 |
A pressure sensor includes a single-mode optical fiber and a fiber Bragg grating coupled to the single model fiber. The sensor detects a wavelength shift of a reflection spectrum of the Bragg grating for input light signals to the single mode fiber at different polarization states. A pressure measurement is obtained by determining at least a pair of mutually orthogonal polarization states for the input light at which the wavelength shift of a reflection spectrum of the Bragg grating is a maximum. |
