Tiknoolajiyadda isha laysarka ee dareenka fiber-ka indhaha Qaybta Labaad

2.2 Mawjadaha hal-hal ahIsha laysarka

Hirgelinta shaandhaynta hirarka hal-mawjadood ee laysarka ah waxay asal ahaan tahay in la xakameeyo sifooyinka jireed ee qalabka ku jiralaysargodka (badanaa hirarka dhexe ee baaxadda hawlgalka), si loo gaaro xakamaynta iyo xulashada qaabka dhererka ee wareegaya ee godka, si loo gaaro ujeeddada hagaajinta hirarka wax soo saarka. Iyada oo lagu saleynayo mabda'an, horraantii 1980-meeyadii, hirgelinta laysarka fiber-ka ee la hagaajin karo waxaa inta badan lagu gaaray iyadoo lagu beddelayo wejiga dhammaadka milicsiga ee laysarka shabagga kala-soocidda ee milicsiga leh, iyo xulashada qaabka godka laysarka iyadoo gacanta lagu wareejinayo oo la hagaajinayo shabagga kala-soocidda. Sannadkii 2011, Zhu et al. waxay isticmaaleen shaandhooyin la hagaajin karo si loo gaaro wax soo saar laysarka la hagaajin karo oo hal-hir leh oo leh ballac cidhiidhi ah. Sannadkii 2016, farsamada cadaadiska xariiqda Rayleigh ayaa lagu dabaqay cadaadiska laba-hir leh, taas oo ah, cadaadiska ayaa lagu dabaqay FBG si loo gaaro hagaajinta laysarka laba-hir leh, isla markaana ballaca xariiqda laysarka ee soo baxaya ayaa la kormeeray isla waqtigaas, iyadoo la helayo kala duwanaansho hagaajin mowjad ah oo ah 3 nm. Wax soo saar deggan oo laba-hir leh oo leh ballac xariiq ah oo qiyaastii ah 700 Hz. Sannadkii 2017, Zhu et al. Isticmaalka graphene iyo micro-nano fiber Bragg shabagga si loo sameeyo shaandho la hagaajin karo oo indhaha oo dhan ah, oo lagu daray tiknoolajiyada cidhiidhiga laser-ka Brillouin, waxay adeegsadeen saameynta kuleylka ee graphene oo u dhow 1550 nm si loo gaaro ballaca khadka laysarka oo hooseeya sida 750 Hz iyo sawir-qaadis degdeg ah oo sax ah oo sawir-qaadis ah oo ah 700 MHz/ms oo ku jira xadka hirarka ee 3.67 nm. Sida lagu muujiyey Jaantuska 5. Habka xakamaynta hirarka ee kor ku xusan wuxuu asal ahaan ku guulaystaa xulashada qaabka laysarka isagoo si toos ah ama si dadban u beddelaya hirarka dhexe ee qalabka ee godka laysarka.

Jaantuska 5 (a) Dejinta tijaabada ah ee hirarka la xakamayn karo ee indhaha-laser-ka fiber-ka ee la hagaajin karoiyo nidaamka cabbiraadda;

(b) Muuqaalka wax soo saarka ee wax soo saarka 2 iyadoo la xoojinayo bamka xakamaynta

2.3 Isha iftiinka laysarka cad

Horumarinta isha iftiinka cad waxay soo martay marxalado kala duwan sida laambadda tungsten ee halogen, laambadda deuterium,laysarka semiconductor-kaiyo isha iftiinka supercontinuum. Gaar ahaan, isha iftiinka supercontinuum, oo hoos timaada kicinta femtosecond ama picosecond oo leh awood aad u badan oo ku meel gaar ah, waxay soo saartaa saameyn aan toosnayn oo kala duwan oo ku jira hagaha hirarka, spectrum-kuna si weyn ayuu u ballaaran yahay, kaas oo dabooli kara wareegga laga bilaabo iftiinka muuqda ilaa ku dhow infrared, wuxuuna leeyahay isku xirnaan xooggan. Intaa waxaa dheer, iyadoo la hagaajinayo kala firdhinta iyo aan toosnayn ee fiber-ka gaarka ah, spectrum-keeda xitaa waxaa loo fidin karaa xarigga dhexe ee infrared. Noocan isha laysarka ah ayaa si weyn loogu dabaqay meelo badan, sida sawir-qaadista isku-dhafka indhaha, ogaanshaha gaaska, sawir-qaadista bayoolojiga iyo wixii la mid ah. Sababtoo ah xaddidaadda isha iftiinka iyo dhexdhexaadka aan tooska ahayn, spectrum-ka hore ee supercontinuum waxaa inta badan soo saaray muraayadda indhaha ee adag ee laser-ka si loo soo saaro spectrum-ka supercontinuum ee cabbirka muuqda. Tan iyo markaas, fiber-ka indhaha ayaa si tartiib tartiib ah u noqday dhexdhexaad aad u fiican oo lagu soo saaro supercontinuum ballaaran sababtoo ah isku-dhafka weyn ee aan tooska ahayn iyo goobta qaabka gudbinta yar. Saamaynta ugu weyn ee aan tooska ahayn waxaa ka mid ah isku-darka afar-hir, xasillooni-darrada isbeddelka, isbeddelka is-waji, isbeddelka is-dhaafka ah, kala-goynta soliton, kala-baxa Raman, isbeddelka is-beddelka soliton, iwm., saamiga saameyn kastana sidoo kale wuu ka duwan yahay iyadoo loo eegayo ballaca garaaca garaaca kicinta iyo kala-baxa faybarka. Guud ahaan, hadda isha iftiinka ee supercontinuum waxay inta badan ku wajahan tahay hagaajinta awoodda laysarka iyo ballaarinta baaxadda muuqaalka, oo fiiro gaar ah u yeelo xakamaynta isku-xidhnaanta.

3 Soo Koobid

Warqaddani waxay soo koobaysaa oo dib u eegaysaa ilaha laysarka ee loo isticmaalo taageeridda tiknoolajiyada dareenka fiilada, oo ay ku jiraan laysarka cidhiidhiga ah ee xariiqda cidhiidhiga ah, laysarka hal-marxalad la hagaajin karo iyo laysarka cad ee ballaadhan. Shuruudaha codsiga iyo xaaladda horumarinta ee laysarkan ee ku jira dareenka fiilada ayaa si faahfaahsan loo soo bandhigay. Marka la falanqeeyo shuruudahooda iyo xaaladda horumarka, waxaa lagu soo gabagabeynayaa in isha laysarka ee ugu habboon ee dareenka fiilada ay gaari karto wax soo saar laysarka aad u cidhiidhi ah oo aad u deggan wakhti kasta iyo wakhti kasta. Sidaa darteed, waxaan ku bilaabaynaa laysarka ballacyada xariiqda cidhiidhiga ah, laysarka ballacyada xariiqda cidhiidhiga ah ee la hagaajin karo iyo laysarka iftiinka cad oo leh baaxadda faa'iidada ballaaran, waxaanan ogaanaynaa hab wax ku ool ah oo lagu xaqiijin karo isha laysarka ee ugu habboon ee dareenka fiilada iyadoo la falanqeynayo horumarkooda.
