Summary:	鎖模環型雷射光纖光柵信號解調系統,與光纖光柵組成一環型共振腔,以產生的超短脈衝雷射達到主動鎖模之目的,使用鎖模技術產生的脈衝光作為信號源,光纖光柵的信號強度因此而增強,可以讓感測距離增長,並降低光纖光柵雜訊干擾。此外,將光纖光柵固定於揚聲器上並利用於震動信號之量測,量測即時弦波信號,量測振動響應特性,並利用傅立葉轉換轉換成頻域信號,可以有效提升低頻振動的量測精確度,並觀測全頻譜的振動量測性能。 We demonstrated the fiber Bragg grating signal interrogation system by using mode-locked fiber ring laser structure to enhance the performance for fiber Bragg grating sensing and form a ring resonator. Using mode-locked system produces pulsed light as a signal source, which can generate the high peak intensity of the ultra short pulse in the fiber grating interrogation system. Fiber Bragg grating signal interrogation would enhance signal intensity, and also can improve the distance of the measurement and reduce noise levelIn addition, a fiber Bragg grating sensor mounted on a vibration actuator which is fixed on the speaker and used to measure the vibration of the actuator. Real time signal transformed to a frequency domain signals by using fast Fourier transform, this can effectively enhance the accuracy of low-frequency vibration measurement, and enhance the performance of the sensing.
