The demonstrations of evanescent theories and numerical calculating of fiber Bragg gratings are addressed in the following part of this paper. 在論文中首先分析了光纖光柵傳感的原理和數值計算的方法，得出的一些結論對實(shí)驗有很好的指導作用。
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。
