Several materials with large coefficient of expansion were selected to make packaging components, and it was found that the packaging materials have good temperature sensitivity and compatibility with optical fibers. experimental accuracy and repetition of fbg temperature sensitivity and compensation were discussed. have selected several materials which has bigger coefficient of expansion to do packaging components, have made many temperature experiments, there have not flaws, such as aging, crackle, absciss layer, packaging materials have good temperature sensitivity and compatibility with optical fiber ; have designed the simple and practical packaging components, have performed a serials of experiments about accuracy and repetition of fbg wave - length, have obtained the first step conclusion ; have analyzed the result and made comparison between the result of different experiment, have summarized the best packaging effect and several rules to reduce mistskes
本文所做的主要工作包括以下幾個內容：一、選取了常見的熱膨脹系數大的材料製作封裝元件，經過多次一80到80反復測試，封裝元件沒有出現老化開裂、封裝裂紋、空洞、離層等缺陷，封裝材料具有良好的溫敏穩定性及復用性，與光纖相容性較好；二、對光纖光柵進行簡單、實用的封裝處理，就封裝效果的優劣性、波長測量的準確度、重復性和封裝時產生的波長損失等方面進行了一系列的實驗，得出了初步的結論；三、對溫敏和溫度補償式封裝的實驗數據進行了詳細的分析和對比，從數字上對溫變過程中光纖光柵中心波長的改變及溫變曲線進行了定量的分析，在大量實驗數據分析結果的基礎上，總結出哪種材料封裝效果更好，以及如何有效的減小實驗誤差。Traditional micro - displacement actuator always uses heat - expanded materials and piezoelectric ceramic. and these materials universally have many disadvantages, such as small expanding - contracting value, long reaction time, complex driving structure, easily aging and so on, which seriously influence output range and controlled precision
傳統的微位移驅動器的驅動材料多採用熱膨脹元件和壓電陶瓷，由於在這類材料中普遍存在伸縮應變量小、反應時間長、驅動結構復雜、易老化等問題，嚴重影響了驅動器工作范圍的擴大和控制精度的提高。
