【摘要】：探討光纖光柵傳感器(FBG)于光譜分析儀上所讀取的光波頻譜圖的中心波長(zhǎng),在溫度與應(yīng)變作用下,測(cè)試出中心波長(zhǎng)的漂移量與溫度及應(yīng)變的關(guān)系式,結(jié)果顯示其溫度與應(yīng)變的誤差可達(dá)到0.13℃及6με,并對(duì)于混凝土試件溫度的重復(fù)性與穩(wěn)定性都有不錯(cuò)的效果;對(duì)于混凝土試件的應(yīng)變的量測(cè),結(jié)果顯示,FBG傳感器在中心波長(zhǎng)1 548、1 554 nm的應(yīng)變與荷載關(guān)系式分別為0.256、0.235με/N。此簡(jiǎn)單、成本不高的FBG傳感器若能再進(jìn)一步改善后,希望能實(shí)際應(yīng)用于路面結(jié)構(gòu)或交通基礎(chǔ)建設(shè)中溫度與應(yīng)變的量測(cè)。
[Abstract]:In this paper, the central wavelength of the optical wave spectrum which is read by the fiber grating sensor (FBG) on the spectrum analyzer is discussed. Under the action of temperature and strain, the relationship between the drift of the center wavelength and the temperature and strain is obtained. The results show that the error between temperature and strain can reach 0.13 鈩，
