Sensor ea Fiber Optic
Sensor optic ea fiber e entsoe ka mohloli o khanyang, fiber ea ketsahalo, fiber ea ho tsoa, modulator e khanyang, mochine oa leseli, le demodulator.Molao-motheo oa motheo ke ho romela leseli la mohloli oa leseli sebakeng sa modulation ka fiber ea ketsahalo, 'me leseli le sebelisana le litekanyo tse lekantsoeng ka ntle sebakeng sa modulation ho etsa lisebelisoa tsa optical tsa leseli (tse kang matla, wavelength, frequency. , phase, kheloha e tloaelehileng, joalo-joalo) etsahala.Leseli la lets'oao le fetotsoeng le fetoha leseli la lets'oao le fetotsoeng, ebe le romelloa ho photodetector le demodulator ka fiber ea ho tsoa ho fumana litekanyo tse lekantsoeng.
Li-sensor fiber optical li ka aroloa ka mekhahlelo e 'meli ho latela mofuta oa sebopeho: e' ngoe ke sensor e sebetsang (ho utloa);e 'ngoe ke sensor e sa sebetseng (e fetisang leseli).
Sensor e sebetsang
Sebelisa fiber ea optical (kapa fiber e khethehileng ea optical) e nang le kutloisiso le bokhoni ba ho lemoha boitsebiso bo ka ntle e le ntho e utloahalang ho fetola leseli le fetisoang ka fiber ea optical ho fetola matla, mohato, maqhubu kapa polarization ea leseli le fetisitsoeng.Ka ho theola lets'oao le fetotsoeng, lets'oao le lekantsoeng le fumanoa.
Fiber ea optical ha se feela mokhoa oa tataiso o bobebe, empa hape ke ntho e hlokolosi, 'me hangata ho sebelisoa fiber ea mefuta e mengata.
Melemo: sebopeho se kopaneng le kutlo e phahameng.Mathata: Ho hlokahala likhoele tse khethehileng tsa optical, ’me litšenyehelo li holimo.Mehlala e tloaelehileng: fiber optic gyroscopes, fiber optic hydrophones, joalo-joalo.
Sensor e sa sebetseng
E sebelisa likarolo tse ling tse hlokolosi ho utloa liphetoho tse lekantsoeng.Fibre ea optical e sebelisoa feela joalo ka mokhoa oa phetisetso ea tlhahisoleseling, 'me hangata ho sebelisoa fiber ea mofuta o le mong.Fiber ea optical e phetha karolo feela ho tataiseng leseli, 'me leseli le lekanyetsoa le ho feto-fetoha ka mokhoa oa optical fiber-type sensitive element.
Melemo: Ha ho hlokahale likhoele tse khethehileng tsa optical le mekhoa e meng ea theknoloji e khethehileng, eo ho leng bonolo ho e sebelisa, le litšenyehelo tse tlaase.Go tlhoka mesola: kutlo e tlase.Boholo ba tse sebetsang ke li-non-functional optical fiber sensors.
