    Kurongeka kwefiber optic sensors

    Nguva yekutumira: Aug-06-2021

    Fiber Optic Sensor

    Iyo fiber optic sensor inoumbwa nechiedza sosi, chiitiko fiber, yekubuda fiber, mwenje modulator, mwenje detector, uye demodulator. Nheyo yekutanga ndeyekutumira mwenje wemwenje sosi kune modulation nzvimbo kuburikidza nechiitiko fiber, uye mwenje unopindirana nekunze kuyerwa paramita munzvimbo yemodulation kuti iite optical zvimiro zvechiedza (senge kusimba, wavelength, frequency. , chikamu, kutsauka kwakajairika, etc.) kuitika. Iyo yakashandurwa mwenje mwenje inova iyo modulated chiratidzo mwenje, iyo inozotumirwa kune iyo photodetector uye demodulator kuburikidza neinobuda fiber kuti iwane yakayerwa paramita.

    Optical fiber sensors inogona kukamurwa kuita mapoka maviri zvichienderana nerudzi rwechimiro: imwe inoshanda (sensing) sensor; imwe yacho isiri-inoshanda (light-transmitting) sensor.

    Sensor inoshanda

    Shandisa iyo optical fiber (kana yakakosha optical fiber) nekunzwa uye kugona kuona kune ruzivo rwekunze sechinhu chinonzwa kuti ugadzirise mwenje unofambiswa mufiber optical kushandura kusimba, chikamu, frequency kana polarization yechiedza chinopfuudzwa. Nekudzikisa iyo modulated chiratidzo, iyo yakayerwa chiratidzo inowanikwa.

    Iyo optical fiber haingori mwenje dhizaini svikiro, asiwo chinhu chinonzwisa tsitsi, uye akawanda-modhi optical fiber inonyanya kushandiswa.

    Zvakanakira: compact chimiro uye yakakwirira senitivity. Zvakaipa: Special optical fibers inodiwa, uye mutengo wakakwira. Mienzaniso yakajairika: fiber optic gyroscopes, fiber optic hydrophones, nezvimwe.

    Isiri-inoshanda sensor

    Inoshandisa zvimwe zvinhu zvinonzwisa tsitsi kuona shanduko dziri kuyerwa. Optical fiber inongoshandiswa senzira yekufambisa yeruzivo, uye single-mode optical fiber inowanzoshandiswa. Iyo optical fiber inongotora basa mukutungamirira chiedza, uye chiedza chinoyerwa nekugadziriswa pane optical fiber-type sensitive element.

    Zvakanakira: Hapana kudikanwa kweakakosha optical fibers uye humwe hunyanzvi matekinoroji, ari nyore kushandisa, uye mutengo wakaderera. Kukanganisa: kuderera kwekunzwa. Mazhinji eaya anoshanda haasi-anoshanda optical fiber sensors.
