Sensa ya kuwala ya fiber imatha kulumikiza ulusi wowala ndi gwero la kuwala kwa sensa ya photoelectric, ngakhale pamalo opapatiza ikhoza kuyikidwa momasuka, ndipo kuzindikira kungagwiritsidwe ntchito.
Mfundo ndi Mitundu Yaikulu
Ulusi wowala monga momwe tawonetsera pachithunzichi uli ndi pakati ndi chitsulo chokhala ndi mawonekedwe osiyanasiyana a refractive index Cladding. Pamene kuwala kwachitika pa pakati pa ulusi, kudzakhala ndi chitsulo chowala. Kuwunikira konse kumachitika pamwamba pa malire pamene akulowa mu ulusi. Kudzera mu ulusi wowala. Mkati, kuwala kochokera kumapeto kwa nkhope kumafalikira pa ngodya ya madigiri pafupifupi 60, ndipo kumawunikira pa chinthu chomwe chapezeka.
Mtundu wa Pulasitiki
Pakati pake ndi utomoni wa acrylic, wokhala ndi mizu imodzi kapena yambiri yokhala ndi mainchesi a 0.1 mpaka 1 mm ndipo wokutidwa ndi zinthu monga polyethylene. Chifukwa cha kulemera kwake kochepa, mtengo wake wotsika komanso kosavuta kupindika ndi zinthu zina zakhala zinthu zazikulu zomwe zimagwiritsidwa ntchito poyesa fiber optic.
Mtundu wa Galasi
Lili ndi ulusi wagalasi kuyambira 10 mpaka 100 μm ndipo limakutidwa ndi machubu achitsulo chosapanga dzimbiri. Limapirira kutentha kwambiri (350° C) ndi makhalidwe ena.
Njira Yodziwira
Masensa a ulusi wowala amagawidwa m'njira ziwiri zodziwira: mtundu wa kutumiza ndi mtundu wa kuwunikira. Mtundu wa kutumiza umapangidwa ndi chotumizira ndi cholandirira. Mtundu wowunikira kuchokera ku mawonekedwe. Umaoneka ngati muzu umodzi, koma kuchokera ku mawonekedwe a nkhope yomaliza, umagawidwa m'mitundu yofanana, mtundu womwewo wa Axial ndi mtundu wolekanitsa, monga momwe zasonyezedwera kumanja.
Khalidwe
Malo okhazikika opanda malire, ufulu wapamwamba
Pogwiritsa ntchito ulusi wowongoka wosinthasintha, ukhoza kuyikidwa mosavuta m'mipata yamakina kapena malo ang'onoang'ono.
Kuzindikira zinthu zazing'ono
Nsonga ya mutu wa sensa ndi yaying'ono kwambiri, zomwe zimapangitsa kuti zikhale zosavuta kuzindikira zinthu zazing'ono.
Kukana bwino chilengedwe
Chifukwa chakuti zingwe za fiber optic sizingathe kunyamula magetsi, sizingasokonezedwe ndi magetsi.
Bola ngati kugwiritsa ntchito zinthu zoteteza kutentha, ngakhale m'malo otentha kwambiri kungadziwikebe.
