PRESSURE SENSOR UTILIZING BRAGG GRATING WITH SINGLE MODE FIBER |
| 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. |

1. A pressure sensor comprising:
a single-mode optical fiber; a fiber Bragg grating coupled to the single mode optical fiber; a detector to detect a wavelength shift of a reflection spectrum of the Bragg grating for light signals input to the single mode fiber at different polarization states; and logic to obtain a measurement of pressure on the Bragg grating 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. |
