| 英文摘要 | Provided are a temperature sensor and an active phase-shifted grating-based temperature sensing system, relating to a fibre sensing technical field. The temperature sensor comprises a pump laser, a wavelength division multiplexer, an optical detector and an active phase-shifted fibre grating with π phase shift. Pump light emitted by the pump laser enters the active phase-shifted fibre grating through the wavelength division multiplexer. The active phase-shifted fibre grating absorbs the pump light and emits laser light, which travels back through the wavelength division multiplexer and enters the optical detector. The optical detector measures output power of the active phase-shifted fibre grating, to analyze the power to obtain ambient temperature of the active phase-shifted fibre grating. Compared with wavelength demodulation based fibre grating sensors, this temperature sensor can obtain ambient temperature of the active phase-shifted fibre grating solely by analyzing output power of the active phase-shifted fibre grating measured by the optical detector. |
