At the same time, we combine the dynamic filter technique which chose different passband with different depth to hold the high signal-to-noise ratio. 同時(shí)融入動(dòng)態(tài)濾波技術(shù)，根據不同深度選擇了不同的通帶范圍，有效地保證了信號的信噪比。
Among the tunable filter technologies of optical fiber grating sensors, the peak method is an usual way, but it has poor precision and the result is unstable. 摘要在光纖光柵傳感懸臂梁調諧濾波技術(shù)中，峰值法進(jìn)行波長(cháng)檢測誤差大，精度低，測量結果不穩定。
