Itekhnoloji ye-Laser ye-Laser ye-fiber fiber

Itekhnoloji ye-LaserI-fiber officalimvakalelo yenxalenye enye

Itekhnoloji ye-fiber ye-fiber ye-fiber ye-fiber iluhlobo lwetekhnoloji yokuqonda iphuhliswe kunye netekhnoloji yonxibelelwano ye-fiphal kunye ne-fiber ye-filical filical filical kunye ne-filical filical filical filical filical, kwaye yenye yezona zinto zisebenzayo zetekhnoloji yefoto. Inkqubo yokuveliswa kwe-fiber ye-fiber iqulethe ikakhulu i-lar, i-fiber yothungelwano, i-fiber yokuhambisa, indawo yokufaka imo yemodyuli, iphononongwe ngemozulu kunye namanye amalungu. Iiparameter ezichaza iimpawu zokukhanya ezibandakanya ubunzulu, iSigaba, iSigaba sePolarization, njl. Njl. Umzekelo, xa ubushushu, ubunzima, uxinzelelo, ukwangoku, ukuntywila, ukujikeleza, ukugoda, ukugoba, ezi paramitha zichaphazela ngokulandelelana. I-fiber ye-fiber ifible isekwe kubudlelwane phakathi kwale paramitha kunye nezinto zangaphandle zokufumanisa amanani ahambelana noko.

Zininzi iintlobo zeumthombo we-laserIsetyenziswe kwiinkqubo zokuziva zine-fiber ze-fiber ze-fiber, ezinokwahlulwa zangamacandelo amabini: ConentImithombo yase-laserkunye nemithombo yokukhanya engahambelaniyo, engangqinelaniImithombo yokukhanyaubukhulu becala ubandakanya ukukhanya kwe-incondeses kunye nee-Deds ezikhutshelweyo, kunye nemithombo yokukhanya ehambelanayo kubandakanya i-lasers eqinileyo, i-iasts ye-flatt,I-Semiconductor LaserkwayeI-Fiber Laser. Oku kulandelayo ikakhuluUmthombo wokukhanya we-laserIsetyenziswe ngokubanzi kwibala le-fiber kwimidlalo yakutshanje: Umda onqamlezileyo i-laers engapheliyo, i-wave-wavenclon enye isuka rhoqo kunye ne-White Laser.

1.1 IIMFUNO ZEEMFUNO ZEXESHA LOKUGQIBELAImithombo yokukhanya ye-laser

Inkqubo yokuqonda i-fiber ye-fiber ayinakwahlulwa kumthombo we-laser, njengomqondiso wokuthoba umqondiso, imithombo yokukhanya kwe-fiber ngokwayo, i-Isser Linew kunye neempawu zengxolo kunye neempawu zengxolo zidlala indima yokuthatha isigqibo. Kwiminyaka yakutshanje, ngokuphuhliswa kweenkqubo zokuhamba kwexesha elide kwi-fiber ze-fiber i-fiber i-fiber ye-fiber ye-fiber ye-fiber, ishishini lobuchwephesha bobuchwephesha bokuyifumana itekhnoloji yokuhlola ukuhlalutywa kwe-bibles, i-Optical Rican isebenzisa imiqondiso ye-laser. Izibonelelo zokusonjululwa okuphezulu (isisombululo senqanaba lemilimeter) kunye nemvakalelo ephezulu (ukuya kuthi ga kwi-100 i-DBM) iye yaba yenye yetekhnoloji yokulinganisa i-fibed kunye netekhnoloji yokwenyani. Itekhnoloji ye-Ofisi yeTekhnoloji kukusebenzisa umthombo wokukhanya okuphezulu ukuze kufezekiswe ukuntywila ngokuhamba kwexesha, ukwenziwa komthombo we-laser kumisela izinto eziphambili ezinje ngoluhlu lwe-ORDR lokuchonga, uvakalelo kunye nesisombululo. Xa umgama wokubonisa umgama usondele kubude obuhambelanayo, ubukhulu bomqondiso wokubetha buya kuthi batyhafe nge-inponiced nge-coander τ / τc. Kwimithombo yokukhanya yaseGaussian enemilo yobume bendawo, ukuqinisekisa ukuba ukubetha rhoqo kune-90%, ubudlelwane obuphakathi kwe-80 km, i-fast ye-FITE i-80 ye-HZ. Ukongeza, ukuphuculwa kwezinye iinkqubo kwakhona kubekwa phambili iimfuno eziphezulu ze-widwidth yomthombo wokukhanya. Umzekelo, kwi-fiber fiber ye-fiber hydrophone, umtya we-firdment umthombo wokukhanya ubeka ingxolo yengxolo kwaye umisela umqondiso obunokumetwa kwenkqubo. Kwi-rismlouin yexesha lokujonga i-Domain i-Acking (iBhodr), isisombululo semilinganiselo yobushushu kunye noxinzelelo ikakhulu zimiselwa ikakhulu ngumgca wokukhanya. Kwi-fiber fiber optic gyro, i-cohence ye-Poech yamaza anokwandiswa ngokunciphisa ububanzi belayini, ngaloo ndlela kububanzi bendawo yokuhlaziya, kunye nokuqinisekisa ukuchaneka komlinganiso we-fiber optic gyro.

1.2 Iimfuno zeMithombo yeSpeepy

I-wavelength eyodwa ikhutshiwe i-lavelengd wavelength eguqukayo, inokutshintsha i-Waveers ezininzi ezilungisiweyo, zinciphise iindleko zolwakhiwo lwenkqubo, yinxalenye engenakuphikwa kwenkqubo yokuvala kwe-fiber yefibre. Umzekelo, ekutsaleni irhasi yerhasi ye-fiber, iintlobo ezahlukeneyo zeegesi zineencopho ezahlukeneyo zegesi. Ukuqinisekisa ukusebenza ngokukuko kokukhanya xa irhasi yomlinganiso yanele kwaye ifezekise ubuntununtunu bokuphakamisa, kuyimfuneko ukulungelelanisa i-wavelecth yosulelo olunomthombo wothumelo kunye nemolekyuli yerhasi. Uhlobo lwerhasi enokufunyanwa ngokuyintloko isungulwe ngumthombo wokukhanya. Ke ngoko, emxinwa le-LIADS enesitali esine-suning yebhendi ebambelelayo inomgangatho ophezulu wokuguquguquka kwiinkqubo ezinjalo. Umzekelo, kwezinye iinkqubo zokuhambisa i-fiber ze-fiber ze-fiber ze-fiber ezikhoyo ngokusekwe kwiVidiyo ye-Optical, i-laser kufuneka ikhawuleziswe ngokukhawuleza ekufumaneni izinto ezilinganayo, kwaye isantya semozulu ye-Laser eguqukayo idla ngokufuneka i-10 PM / μs. Ukongeza, i-wavelength yangaphantsi komgca ongenamncinci i-Laser ikwanokusetyenziswa ngokubanzi kwi-lidar, i-Laser ekude kunye nokusonjululwa okuphezulu kunye nokusombulula izinto ezibonakalayo kunye nezinye izinto ezibonakalayo. Ukwenzela ukufezekisa iimfuno zeParamers yeNtsebenzo yeTeunding, Tunning ngokuchanileyo kunye nesantya sesantya esincinci kwicandelo le-fiber kwi-fiberlid lavent therwidth lise, ingxolo enkulu ye-Ultra, kunye ne-Ultra-iziko lokuphuma kwamandla.

1.3 Ibango lemithombo yokukhanya eMhlophe

Kwintsimi yemvakalelo ye-Optical, i-Laser esemgangathweni esemgangathweni ye-White ibaluleke kakhulu ekuphuculeni ukusebenza kwenkqubo. Umngxunya obanzi we-shoctrum ye-White Laser yokukhanya, kokukhona usetyenziso lwayo olubanzi kwinkqubo yokuthathwa kwe-fiber yefibre. Umzekelo, xa usebenzisa i-fiber bragg yokutsala inethiwekhi yenzwane, uhlalutyo lobuchule okanye indlela yokuqhubela phambili yecebo lokucoca ifilitha ingasetyenziselwa ukwenziwa. Okwangaphambili esebenzisa i-spectrometer ukuba avavanye ngokuthe ngqo i-FBG ye-FBG ye-FBG ye-FBG kwinethiwekhi. Elokugqibela isebenzisa isihluzo sesalathiso sokulandela umkhondo kwaye silungelelanise i-FBG kwimvakalelo ye-FBG, zombini ezifuna umthombo wokukhanya okubanzi njengoMthombo wokukhanya wovavanyo kwi-FBG. Kuba inethiwekhi yokufikelela nganye ye-FBG iya kuba nelahleko ethile, kwaye ine-bandwidth engaphezulu kwe-0.1 NM, i-demonoding ngaxeshanye ye-FBG ifuna umthombo wokukhanya okubanzi kunye nebhendi ephezulu. Umzekelo, xa usebenzisa ixesha elide lokutsala (i-LPFG) yokubona imvakalelo, kuba i-bandwidth ye-Peak enye i-10 NM, i-spectur yokukhanya kwe-ntwidth eyoneleyo kunye ne-verctur evuthiweyo eneempawu zayo ngokuchanekileyo. Ngokukodwa, i-acoustic fiber Ke ngoko, ukuvavanywa kwe-Gynamic kunye noluhlu lweTuuning olubanzi lubeka umngeni omkhulu kuluhlu lwe-bandwidth of thework. Ngokufanayo, kwiminyaka yakutshanje, ukuThintelwa kweFragg Giber kuye kwasetyenziswa ngokubanzi kwintsimi yefibre. Ngenxa yokulahleka kwelahleko ye-viak ye-Peectricus eninzi, uluhlu lokuhambisa amaWavelele luhlala lufikelela kwi-40 NM. Indlela yokuqonda idla ngokuthelekisa intshukumo yesalamane phakathi kweemvavanyo zothumelo ezininzi, ke kufuneka ukulinganisa i-spectrum yaso ngokupheleleyo. I-bandwidth kunye namandla obukhali obubanzi bokukhanya kuyafuneka ukuba ngaphezulu.

Kwimigca ye-caviber ye-fiber i-fiber i-lars, i-Laser emxinwa i-laser ye-Laser yemodi ye-cheitudinal ifunyenwe ngokuncitshiswa kobude bomhlaba kunye nokwandisa ixesha lemodeli yexesha elide. Ngo-2004, uSpiegelberg et al. Ifumene i-Dedeitudinal Doumorinal Doumow Dinwidth Light Imveliso ye-2 khz ngokusebenzisa indlela ye-DBR. Ngo-2007, uShen et al. Isebenzise i-2 cm e-of erbicon ye-fiber yokubhala i-FBG kwi-fiberseritive ye-bible ye-Bible, kwaye yayityhalela ifibre esebenzayo ukwenza i-compact witner gener equist, esenza ububanzi bemveliso ye-TORP. Ngo-2010, yang et al. Sebenzisa i-2cm ye-2cm emfutshane ye-2cm emfutshane edibeneyo ne-filter ye-firter ye-fbg ukufumana igalelo lendlela enye ye-Lostbal Ngo-2014, iqela lalisebenzisa i-cavity emfutshane yomgca (i-veloped right ring) idityaniswa ne-FBG-FP yokucoca i-FBG-FP ukufumana igalelo lomsebenzi wobubanzi bomsebenzi, njengoko kubonisiwe kwi-3. Ngo-Cai et al. Sebenzisa isakhiwo esifutshane se-1.4cm sokufumana imveliso yomgangatho wemveliso enobume bemveliso engaphezulu kwe-114 MW, i-440.3 ye-ntshu enezinto ezimbi ze-4.1 khz. Ngo-2013, Meng et al. Ukusetyenziswa kwe-rillouin ukupasa i-erbium ye-erbium ene-fiber yeringi yeringi ye-bias epheleleyo yokufumana ifowuni epheleleyo yokufumana indlela ye-lotudinal ye-lest, igalelo lengxolo yengxolo ephantsi, imveliso yengxolo ye-Inser yengxolo ye-10 mw. Ngo-2015, iqela lasebenzisa i-cavity yeringi eyayiqulunqwe nge-fiber ye-fiber ye-Erbium engama-45 e-Erbium njengoko i-rillouin yasasaza i-Piner Platating Fin Pinaw fumana i-Piner Proner ukuya kwimveliso ephantsi kunye ne-munwidth yokukhuphela igalelo.
