Ukuhlukaniswa nohlelo lokushintshashintsha kwe-Laser Modulator

I-Laser ModulatorUhlobo lokulawula izakhi ze-laser, akusisekelo njengezinhlamvu, amalensi nezinye izinto, noma kuhlanganiswe kakhulu njengama-lasers,imishini ye-laser, ingabe izinga eliphakeme lokuhlanganiswa, izinhlobo nemisebenzi yemikhiqizo yeklasi ledivayisi. Kusuka ekuvezweni okuyinkimbinkimbi kwegagasi elikhanyayo, kungabonakala ukuthi izici ezithinta igagasi elikhanyayo linamandla a (r), isigaba ω), ngokulawula lezi zinto ezingashintsha isimo segagasi elikhanyayo, i-laser modulator ehambisanayo yiIsimonyo sokuqina, Isikhulisi sesigaba, i-Frequency Shifter kanye ne-Deflector.

2. Isilinganiselo sesigaba: Kusetshenziselwa ukulawula isigaba sogongolo, ukukhuphuka kwesigaba kubizwa ngokuthi yi-lag, ukwehla kwesigaba kubizwa ngokuthi ukuhola. Kunezinhlobo eziningi zamamodi wesigaba, futhi izimiso zazo zokusebenza zihluke kakhulu, ezinjengama-photolelastic modulators, ama-perp-speed electro-speed electro-speed electro-speed electro-speed electro-speectical Isimo sokulibazisa, njll. Ngakho-ke, amashidi wesigaba esiguquguqukayo, wonke ama-modulale asuselwa ezimisweni ezahlukahlukene zokusebenza .

3. Imvamisa i-shifter: isetshenziselwa ukushintsha imvamisa yamagagasi akhanyayo, isetshenziswa kabanzi ezinhlelweni ze-laser eziphakeme noma imephu yemephu, nge-acousto-optical frequency swirter njengommeleli ojwayelekile.

4. I-Deflector: Isetshenziselwa ukuguqula ukuqondiswa kokusakazwa kwe-beam, uhlelo olujwayelekile lwe-galvanometer kungenye yazo, ngaphezu kwe-mems galvanometer, i-electro-optical deflector kanye ne-acousto-optical deflector.

Sinomqondo ojwayelekile we-laser modulator, okungukuthi, izakhi ezingalawulwa ngamandla futhi zishintshe ezinye izakhiwo ze-laser, kepha zifuna ukwethula ngokuphelele imikhiqizo ethile ye-laser modulator, i-athikili kuphela ekude nokwanele. Ngakho-ke, okokuqala, gxila ku-modulator yokuqina. I-Modulator yokuqina njengohlobo lwe-modulator esetshenziswa kabanzi kuzo zonke izinhlobo zezinhlelo ze-optical, ukuhlukahluka kwalo, ukusebenza okuhlukile kungachazwa njengenkimbinkimbi, namhlanje ukwethula, uhlelo lwe-electro, uhlelo lwe-electro-optic, uhlelo lwe-acousto-optic kanye nohlelo lwe-liquid crystal.

1. I-Mechanical Scheme: I-Mechanic Amandla Modulator iyindlela yokuqala futhi esetshenziswa kakhulu yamandla ama-Modulator. Umgomo uwukushintsha isilinganiso sokukhanya kwesilinganiso no-P ukukhanya kwesibani se-polarised ngokujikeleza ipuleti le-half-wave, futhi uhlukanise ukukhanya yi-polarizer. Ukusuka kulungiswa kwencwajana kokuqala kuya kokunemba kwanamuhla ngokunemba okuthe xaxa nokunemba okuphezulu, izinhlobo zayo zomkhiqizo kanye nentuthuko yohlelo lokusebenza zivuthiwe kakhulu.

2 Isimo se-polarization sokweshintsha kogongolo okhalweni ngemuva kwe-electro-optic crystal enenkambu kagesi. Ukuqina kokukhanya okukhishwe kungalawulwa ngokushintsha ubukhulu benkambu kagesi, kanye nonqenqemeni lokunyuka / lokuwa kwesilinganiso se-NS lungafinyelelwa.

I-3. Isikimu se-Acousto-Optic Ngokushintsha ukusebenza kahle kokuphazamiseka, amandla okukhanya okungu-0 nokukhanya okungu-1 kungalawulwa ukuze kufinyelelwe inhloso yokulungisa amandla okukhanya. I-Acoustooptic Gate (Optical Attenuator) inezimpawu zejubane lokushintshanisa okusheshayo kanye nomkhawulo omkhulu womonakalo.

I-4 Liquid Crystal Solution: Idivayisi ye-Liquid Crystal ivame ukusetshenziswa njengepuleti ye-wave eguquguqukayo noma isihlungi esiguqukayo, ngokusebenzisa i-drive voltage kuwo womabili ama-crystal board ukwengeza i-polarization short, ingenziwa ku-crystal shutter noma eguqukayo I-Atycuator, umkhiqizo unesici esikhulu ngokukhanya, izici eziphakeme zokwethenjwa.
