摘要: 我們研究光纖光柵感測,在本實驗中,我們建立了加速度及溫度感測系統。在偵測光柵波長方面,本實驗分別以Mach- Zender干涉儀系統與可調式Fabry -Perot系統偵測光波長變化。 感測上我們以摻鉺漚纖光線產生感測用的寬頻光源。並且以模擬方式預估摻鉺光纖的理想長度。 本實驗得到初步結果是Mach-Zender 干涉儀適合量測交流訊號,可調式Fabry-Perot適合量測直流訊號。以Mach-Zenhder干涉儀量測變加速最小量測到0.00074m/s2/√HZ。以Fabry-Perot量測等加速最小量測到0.0707m/s2√HZ,以及量測溫度得到波長變化與溫度良好之線性關係,其斜率為0.01512nm/℃°。
We study the fiber Bragg grating sensors, the accelerometer and temperature sensor systems are set up in our experiment. For the wavelength-shift detection, we use the Mach-Zehnder interfero-meter and the Fabry-Perot filter to detect the output signal of fiber Bragg Grating. The broad-band erbium-doped fiber is used as light source. We optimize the length of erbium-doped fiber by simulation. It is found that the Mach-Zender interferometer is suitable for AC signal sensor and gets a minimum detectable acceleration is 0.00074m/s2/√HZ. The Fabry-Perot filter is suitable for DC signal sensor and get a minimum detectable acceleration signal of 0.0707m/s2√HZ In temperature sensor, the wavelength-shift is linear with temperature, the slop is 0.01512nm/℃°.
