Fbg - based strain sensor has many virtues such as unerodibility , absolute code of wavelength , ability for anti - jamming , simple structure and easy execution , etc . so it can replace the traditional mechanical and electrical strain sensor in civil engineering , and has prosperous outlook in the application 光纖光柵應(yīng)變傳感器具有耐腐蝕、波長絕對編碼、抗干擾能力強、結(jié)構(gòu)簡單、實施方便等特點,在土木工程方面可取代傳統(tǒng)機械電子式應(yīng)變傳感器,具有很好的應(yīng)用前景。
Sensors using fbg as the sensing component have many advantages including light weight , small size , anti electromagnetism interference , convenience in fiber connecting , wavelength absolute coding etc . multiple point detection of materials ( temperature , strain etc . ) can also be achieved by connecting several sensors into a net using variety of multiplex techniques and embedding it into or sticking on the surface of the material or structure 以光纖布拉格光柵( fbg )為傳感元件的傳感器具有重量輕、體積小、抗電磁干擾、易于光纖連接、波長絕對編碼等優(yōu)點,還能把多個傳感器利用各種復(fù)用技術(shù)連接成傳感網(wǎng)絡(luò),埋入材料和結(jié)構(gòu)內(nèi)部或貼裝在其表面,實現(xiàn)對其特性(如溫度、應(yīng)變等)的多點監(jiān)測。
