Brillouin optical time domain analyzer DSTS Distributed fiber ntau optic kub strain sensor BOTDA1000
Ntsuas Txoj Cai
Raws li kev txhawb nqa Brillouin scattering effect, Brillouin optical time domain analyzer BOTDA siv ob lub ultra-nqaim kab dav laser lub teeb qhov chaw, uas yog lub twj tso kua mis (pulsed optical signal) thiab sojntsuam (nruam kho qhov muag teeb liab), txhaj tshuaj kho qhov muag teeb liab ntawm ob qho tib si kawg. sensing fiber ntau, ntsuas thiab ntes cov teeb liab kho qhov muag ntawm lub pulsed kho qhov muag kawg ntawm qhov pom fiber ntau, thiab ua cov ntaub ntawv ceev ceev tau txais thiab ua tiav.
Tshuab kom zoo dua
· Ultra-ntev kev ncua deb kev ntsuas kev faib tawm, nrog qhov ntsuas siab tshaj plaws ntawm 60km
· Kub, lim thiab spectrum ntsuas
· Kev ntsuas qhov tseeb, ruaj khov thiab txhim khu kev qha
· Tsis muaj zaus coding, tsis cuam tshuam los ntawm lub teeb qhov chaw siv zog hloov pauv, fiber ntau microbending, fiber ntau hydrogen poob, thiab lwm yam
· Ib hom kev sib txuas lus fiber ntau tuaj yeem siv ncaj qha rau hauv lub sensor, thiab "kev sib kis" thiab "kev paub" yog kev koom ua ke
