AstaamahaModulator AOM acousto-optic
U adkeyso awooda sare ee indhaha
Modulator-ka AOM acousto-optic wuxuu u adkeysan karaa awoodda leysarka ee xooggan, isagoo hubinaya in leysarka awoodda sare ay si habsami leh u dhex mari karaan. Isku xirka laser-fiber-ka,modulator fiber acousto-opticiftiinka joogtada ah u beddela iftiin garaaca. Iyadoo ay ugu wacan tahay wareegga shaqada ee aadka u hooseeya ee garaaca indhaha, inta badan tamarta iftiinka waxay ku dhex taal iftiinka eber. Iftiinka kala-duwanaanshaha dalabka koowaad iyo nalka eber-dalabka ah ee ka baxsan kristal acousto-optic ayaa faafiya qaab ka duwan alwaaxyada Gaussian. Inkasta oo ay la kulmaan shuruudaha adag ee kala soocida, qayb ka mid ah tamarta iftiinka ee iftiinka eber-ku-salaysan waxay ku ururaan cidhifka collimator fiber indhaha oo aan lagu gudbin karin fiber-ka indhaha, ugu dambeyntii gubanaya iyada oo loo marayo collimator fiber indhaha. Qaab dhismeedka diaphragm-ka waxaa lagu dhejiyaa wadada indhaha iyada oo loo marayo saxan sare oo sax ah oo lix-cabbir ah si loo xaddido gudbinta iftiinka kala-duwan ee xarunta isku-dhafka, iyo nalka eber ayaa loo gudbiyaa guryaha si looga hortago iftiinka eber inuu gubanayo collimator fiber indhaha.
Waqtiga kor u kaca degdega ah
Isku xirka laser-fiber-ka oo dhan, wakhtiga degdega ah ee u kaca garaaca wadnaha ee AOMmodulator acouste-opticwaxay hubisaa in garaaca garaaca garaaca nidaamka uu si wax ku ool ah u dhex mari karo ilaa xadka ugu badan, iyadoo laga hortagayo buuqa saldhiga inuu soo galo wakhtiga-Domain acouste-optic shutter (time-domain pulse gate). Xudunta u ah in la gaaro wakhtiga kor u kaca degdega ah ee garaaca indhaha ayaa ah in la dhimo wakhtiga ku-meel-gaarka ah ee hirarka ultrasonic iyada oo loo marayo iftiinka iftiinka. Hababka ugu muhiimsan waxaa ka mid ah yaraynta dhexroorka dhexda ee iftiinka iftiinka dhacdada ama isticmaalka qalab leh xawaare sare si loo sameeyo crystals acoust-optic.

Isticmaalka tamarta hooseeya iyo kalsoonida sare
Dayax gacmeedyadu waxay leeyihiin ilo xaddidan, xaalado adag iyo bay'ad adag, kuwaas oo shuruudo sare ku soo rogaya isticmaalka tamarta iyo isku halaynta modulators fiber indhaha AOM. Fiber indhahaModulator AOMwuxuu qaataa kiristaalo tangential acousto-optic gaar ah, kaas oo leh arrin tayo sare leh oo acousto-optic M2. Sidaa darteed, isla shuruudaha hufnaanta kala-duwanaanta, isticmaalka awoodda wadista ee loo baahan yahay waa mid hooseeya. Modulator-ka fiber-optic-ga ee acoust-optic modulator-ka wuxuu qaataa nashqadan awoodda yar, taas oo aan hoos u dhigin baahida loo qabo isticmaalka awoodda wadista iyo badbaadinta kheyraadka xaddidan ee dayax-gacmeedka, laakiin sidoo kale waxay hoos u dhigtaa shucaaca korantada ee calaamadda wadista waxayna yareysaa cadaadiska kulaylka ee nidaamka. Marka loo eego shuruudaha geeddi-socodka mamnuuca ah (xaddidan) ee alaabada dayax-gacmeedka, habka rakibaadda kristal ee caadiga ah ee modulators fiber-optical acousti-optic oo keliya ayaa qaata habka isku-xidhka caagga silikoon ee hal dhinac ah. Marka caagga silikoonku uu ku guuldareysto, cabbirada farsamada ee crystals ayaa isbeddeli doona xaaladaha gariir, taas oo aan buuxin shuruudaha nidaamka alaabta hawada. Isku xirka laser-ka, kristanta modulator-ka fiber-optical acoust-optic waa mid go'an iyadoo la isku darayo hagaajinta farsamada iyo xiritaanka caag silikoon ah. Qaab dhismeedka rakibaadda dusha sare iyo hoose ee hoose waa mid isku mid ah intii suurtagal ah, isla mar ahaantaana, goobta xiriirka u dhexeeya dusha crystal iyo guryaha rakibidda ayaa la kordhiyaa. Waxay leedahay faa'iidooyinka awoodda kala-baxa kulaylka xooggan iyo qaybinta heerkulka simmetrical ah. Collimators caadiga ah waxaa lagu hagaajiyaa caag silikoon ah oo isku xidhan. Marka la eego xaaladaha heerkulka sare iyo gariirka, waxaa laga yaabaa inay beddelaan, saameynayaan waxqabadka alaabta. Qaab dhismeedka farsamada ayaa hadda la qaatay si loo hagaajiyo collimator fiber optical, kaas oo kor u qaadaya xasilloonida badeecada oo buuxisa shuruudaha nidaamka alaabta hawada.
