【摘要】：本文研究了光纖涂覆層對(duì)高頻CO_2激光刻寫的長(zhǎng)周期光纖光柵的溫度傳感特性的影響,發(fā)現(xiàn)在50~100℃溫度范圍內(nèi),帶涂覆層的長(zhǎng)周期光纖光柵的溫度靈敏度跟剝?nèi)ネ扛矊涌虒懙拈L(zhǎng)周期光纖光柵的溫度靈敏度一樣,均可以達(dá)到100pm/℃。實(shí)驗(yàn)表明:光纖涂覆層對(duì)長(zhǎng)周期光纖光柵的溫度傳感特性沒有顯著影響,但帶涂覆層的長(zhǎng)周期光纖光柵以其機(jī)械強(qiáng)度的優(yōu)勢(shì)更適合用在低溫測(cè)量中。
[Abstract]:In this paper, the effect of fiber coating on the temperature sensing characteristics of long period fiber gratings written by high frequency CO_2 laser is studied. It is found that the temperature range is 50 ~ 100 鈩，
