Yini a i-fiber optic grating demodulator

Ezikhathini eziningi ezikhethekile, izinzwa ze-fiber optic grating zinezici eziningi izinzwa zendabuko ezingenazo. I-Fiber Bragg Grating, njengenzwa ehlakaniphile, inezinzuzo zosayizi omncane, isisindo esilula, ukumelana nokugqwala, ukumelana okuqinile nokuphazamiseka kwe-electromagnetic, ukuhlanganiswa okulula, kanye nesakhiwo esilula. Ingangcwatshwa ngaphakathi kwento ehloliwe kanye nokokusebenza ukuze kutholwe ubuningi obubonakalayo njengokucindezela, izinga lokushisa, ukucindezeleka, ubunzima, izinga lokugeleza, izinga lokugeleza, kanye ne-viscosity.

I-Fiber Bragg Grating (FBG) izinzwa zisheshe zaba yizinzwa ezinhle kakhulu, ekwazi ukukala izilinganiso ezihlukahlukene zomzimba njengezinga lokushisa, ubunzima, kanye nengcindezi. Inezinzuzo zokuzwela okuphezulu, akukho ukuphazamiseka kwe-electromagnetic, ukusebenza okuhle okungangeni manzi, usayizi omncane, isisindo esilula, ukwethembeka okuphezulu, futhi ingashumeka ezintweni eziyinhlanganisela. I-FBG ithola ulwazi lwezinzwa ngokumodela ubude bebanga besikhungo sokubonisa ngamapharamitha angaphandle. Ngakho-ke, isihluthulelo sokwehliswa kwenani ezinhlelweni zokuzwa ze-FBG ukukala uguquko kubude obuphakathi nendawo bokubukeka kwayo.

Okwamanje, I-FBG center wavelength izindlela zokuqeda zingahlukaniswa zibe izigaba ezimbili: (1) izindlela ezisuselwe esilinganisweni se-graft diffraction spectroscopy noma ukuskena kwe-laser okuguqulekayo, njengokusebenzisa ukuthola i-CCD, izihlungi ezithintekayo, njll; (2) Ukusebenzisa izihlungi ezingashintshi, njengendlela yokuhlunga emaphethelweni. Ukusetshenziswa kwama-laser aguqulekayo kunezinkinga ezifana nesivinini sokubona kancane kanye nezindleko eziphezulu zesistimu; Indlela yokuhlunga emaphethelweni inezinkinga ezifana nokuphindaphinda amaphuzu amaningi kanye nobubanzi obuphikisanayo nokunemba.. Indlela yokuthola i-CCD isebenzisa i-planar noma igrating yevolumu isetshenziswe kabanzi ngenxa yezinzuzo zayo ezifana nesivinini sokubona okusheshayo., izindleko zesistimu eziphansi, kanye nokuphindaphinda amaphuzu amaningi.

Isimiso se-Fiber Bragg Grating Demodulator

Umsebenzi oyinhloko wokwehliswa kwezimpawu ze-fiber optic grating sensing ukufunda nokuguqula amanani abuyayo wamaza amaphakathi ahlukene we-fiber optic grating., bese uthola izinguquko olwazini lwangaphandle. Ukukhanya okuvela emthonjeni wokukhanya kwe-broadband kwenzeka ku-fiber yenzwa ngokusebenzisa a 50:50 i-coupler ene-bandpass ethile. Kukhona izinzwa eziningi ze-FBG ezinobude obuhlukile besikhungo sokubonisa amaza ku-fiber yezinzwa, kanye nezinzwa ze-FBG ezinobude obuhlukile besikhungo sokubonisa amaza ziboniswa kumaza wamaza ahlangabezana nesimo se-Bragg, kuyilapho ukudluliswa kokukhanya kumaza wamaza angahlangabezani nesimo kwenzeka. Okwamanje, amapharamitha angaphandle ahlelwa abe yi-wavelength ebonisiwe futhi afaka idemodulator ngokusebenzisa i-coupler ukuze kwehliswe. Idemodulator esetshenziswe kulesi sihloko isekelwe ezimisweni zamaleveli amaningi wokuhlukanisa i-diffraction kanye ne-CCD ye-infrared yomugqa womugqa.. Indlela yokubona ithatha umgomo wokuhlakazeka kwegridi yokudlulisela. I-spectrum ebonisiwe icutshungulwa ngokuhlakazeka futhi ikhonjiswe endaweni ezwelayo ye-photosensitive ye-linear array photodetector.. Ngakho-ke, i-spectrum ebonisiwe iguqulwa ibe amasignali kagesi kumaphikseli ahlukene we-linear array photodetector, ezisetshenziselwa ukudilizwa okulandelayo.

Inani le-Fiber Bragg Grating Demodulator

1. Ukubheka izinhlobo zenzwa ye-fiber optic, umkhiqizo omuhle wezinzwa uzothuthukiswa emakethe, futhi ngokuhamba kwesikhathi, kancane kancane izoba uphawu. Kusenegebe elikhulu phakathi kwemikhiqizo enebhrendi nengenalo uphawu mayelana nokuthengiswa kanye nesevisi ngemva kokuthengiswa. Imikhiqizo yomkhiqizo ibaluleke kakhulu isithunzi nesithunzi, ngakho-ke izinhlobo ze-fiber optic sensor zisezinhle.

2. Ikhwalithi, i-fiber Bragg grating demodulator yekhwalithi ephezulu ayiqhathanisi neminye imikhiqizo engenabhrendi ngokwesipiliyoni somsebenzisi. Umkhiqizo wekhwalithi ephezulu uqinile kakhulu ekukhiqizeni, okuzoholela ezintengo zokuthengisa ezingenakuqhathaniswa nemikhiqizo ephansi futhi zizobiza kancane.

3. Sesha okwengeziwe, ungasesha imikhiqizo efanele ye-fiber optic demodulator online, funda kabanzi mayelana nezingcaphuno ezinikezwe izinkampani ezihlukene zezinzwa ze-fiber optic grating, bese ukhetha umkhiqizo ocabanga ukuthi ulungele uhla lohlelo lwakho lokusebenza. Imakethe inkulu kakhulu, ngakho qhathanisa futhi uthole eminye imikhiqizo evumayo.

Ama-demodulators e-Fiber Bragg grating anezinhlobonhlobo zezinhlelo zokusebenza emikhakheni efana namandla wamandla, amakhemikhali e-petrochemicals, izakhiwo zezimboni kanye nezomphakathi, nezinye izinkambu ezidinga izinga lokushisa lesikhathi sangempela nokuqapha kwengcindezi. The use of fiber optic grating sensing technology can achieve long-distance measurement and monitoring, enezici zebanga elibanzi lokulinganisa, ukunemba okuphezulu, kanye nokulungiswa okuphezulu. Inezinzuzo ezindaweni ezinokhahlo ezinokuphazamiseka okuqinile kwe-electromagnetic noma izinto ezivuthayo neziqhumane.
Ukuthuthukiswa kwezimboni kanye nokukhuthazwa kwesikali kwezinzwa ze-fiber optic zivumelana nezidingo zokuthuthukiswa komnotho kazwelonke. Ucwaningo kanye nezimboni ze-fiber optic sensor technology sekuyinzwa esetshenziswa kahle emandleni nakwezinye izimboni.. Ngokwesiko, I-fiber Bragg gratings yehliswa kusetshenziswa ama-spectrometer, ama-monochromators, namamitha we-wavelength. Nokho, lezi zinhlelo zokudiliza zinezihibe ezifana nezindleko eziphezulu kanye nomthamo omkhulu. Ngakho-ke, kuphakanyiswe izindlela eziningi ezilula nezisebenzayo zokudiliza abantu. Kukhona ikakhulukazi ukuphazanyiswa kwe-demodulation technology, ubuchwepheshe bokuhlunga onqenqemeni, ifaniswe ubuchwepheshe bokwehlisa izinga lokuhlunga, ubuchwepheshe bokwehlisa izinga lokuhlunga lokuhlunga, njll. Ubuchwepheshe be-interferometric demodulation bunokunemba okuphezulu kokulinganisa, kodwa ububanzi bokulinganisa bukhawulelwe uhla lwe-spectral lwamahhala lwe-interferometer. Ibanga lokuhlola lobuchwepheshe bokuhlunga onqenqemeni lilingana ngokuphambene nesinqumo, kuyilapho indlela yokuhlunga ehambisanayo ilula futhi iyasebenza, kodwa uhla lokushuna luncane. Indlela yokwehlisa esekelwe kuzihlungi ze-FP eziguqulekayo inezinzuzo ezifana nokuzwela okuphezulu, ukusetshenziswa kwamandla okukhanya okuphezulu, ukusebenza okulula, ububanzi bokushuna, kanye nokuzinza okuhle kwesistimu. Isistimu yokuqapha ukufuduka kwe-wavelength efanele izicelo zobunjiniyela.
