Izinyathelo zokusebenza zei-modulator yesikhala samahhala se-acousto-optic
Isikhala samahhalai-modulator ye-acousto-opticokufakwayo nokukhipha imisebe yokukhanya ngemigodi yokukhanya evulekile, okudinga ukulungiswa okunembile kanye nokulungiswa kwe-engeli ye-Bragg ngohlaka lokulungisa olunezinhlangothi ezintathu. Uma kuqhathaniswa nochungechunge lokuhlanganisa i-fiber, uchungechunge lwesikhala samahhala ludinga izinyathelo ezengeziwe zokulungisa indlela ye-optical, kodwa lunezinzuzo ezifana nezindlela ze-optical eziguquguqukayo kanye nokubuka okunembile kwezindawo ze-diffraction.
1. Izinyathelo zokufaka nokulungisa indawo yonke zochungechunge lwe-acousto-optic modulator lwesikhala samahhala
Ukufakwa nokulungiswa kwe-free space acousto-optic modulator kuyizinyathelo zokusebenza ezivamile zamamodeli amabili, kanje:
Isinyathelo 1: Ngemva kokuba wonke amadivayisi angaphandle kanye namasekethe sekuxhunyiwe, lungisa idivayisi ye-acousto-optic kufreyimu yokulungisa enezinhlangothi ezintathu, lungisa ukuphakama kwedivayisi ye-acousto-optic phezulu naphansi ukuze uvumele umsebe we-laser udlule endaweni efanele yedivayisi ye-acousto-optic. Qaphela: Indawo yokukhanyisa efanele iphakathi kobukhulu bekristalu, futhi iqhele ngo-1.5mm ukusuka ku-electrode yegolide ngaphambi nangemva kokucindezela.
Isinyathelo 2: Vula ugesi we-24V bese ulayisha isignali (kunconywa ukuthi isignali igcinwe ku-5V uma ulungisa iphutha lobukhulu bokuphambuka, ukuze ugesi oshayelayo uqhubeke nokusebenza). Lungisa i-engeli ye-Bragg yeidivayisi ye-acousto-optickwesobunxele nakwesokudla ukuze kufinyelelwe umfutho wokuphambuka okuphezulu kakhulu kwe-first-order.
Isinyathelo 3: Ngemva kokulungisa ukukhanya kwe-diffraction kwe-oda lokuqala kwedivayisi ye-acousto-optic, noma yisiphi isignali singalayishwa ngokuya ngezidingo zokuhlola.
Uhlobo lwe-2 0~5V (isikhala samahhala)
2.1 Incazelo Yesiginali Yokushintshashintsha
Imbobo ethi “0-5V” isetshenziselwa ukulayisha izimpawu zokulawula futhi iyisignali ye-analog engu-0-5V. Cima lapho i-voltage yokufaka ingu-0V, futhi amandla okukhipha e-RF efinyelela esiphezulu lapho i-voltage yokufaka ingu-5V. Indlela yokuguqula yale modeli ngokuyisisekelo ifana ne-“uhlobo lwe-analog lwe-0-5V” oluhlanganiswe ngefayibha, kodwa isakhiwo sendlela yokukhanya sihlukile, sidinga izinyathelo ezengeziwe zokufakwa nokulungiswa.
2.2 Indlela yokuxhuma
I-“RF” yokunikezwa kwamandla okushayela yi-port yokukhipha amandla e-RF. Sicela uyixhume nomugqa wesignali we-BNC ohambisanayo, kanti olunye uhlangothi lomugqa wesignali kufanele luxhunywe ngqo kudivayisi yomsindo nokukhanya nge-BNC. Qaphela ukuthi le modeli isebenzisa i-interface ye-BNC, ehlukile ku-interface ye-SMA yamamodeli amaningi okuhlanganisa i-fiber.
2.3 Ukulawulwa kwamandla
Sicela usebenzise i-screwdriver ye-Phillips ukuze ujikelezise i-knob encane yembobo ohlangothini. Amandla okujikeleza ayanda, kuyilapho amandla okujikeleza ancipha. Sicela uqaphele ukuthi i-knob yokulungisa amandla yale modeli itholakala emgodini omncane ohlangothini, ohlukile embobeni "yokuguquguquka kwe-amplitude" yamanye amamodeli.
3 Uhlobo lokuhambisa olusezingeni eliphezulu (isikhala samahhala)
3.1 Incazelo Yesiginali Yokushintshashintsha
Imbobo 'yokuguqula' isetshenziselwa ukulayisha izimpawu zokulawula futhi iyisignali yedijithali ejwayelekile ye-TTL. Ukunikezwa kwamandla kuqhutshwa ezingeni eliphezulu, futhi i-voltage engu-5V kumele ifakwe ku-terminal "yokuguqula" ukuze kukhiqizwe ukukhishwa kwamandla e-RF. Uma i-terminal yokuguqula isezingeni eliphansi, ukukhishwa kwe-RF kuyacishwa. Izici zokuguqula zale modeli zifana "nohlobo lokuqhuba oluphezulu" lokuhlanganiswa kwefayibha, kodwa isakhiwo sendlela yokukhanya sihlukile, sidinga ukufakwa okwengeziwe kanye nezinyathelo zokulungisa. Qaphela: Ukunikezwa kwamandla kuqhutshwa ezingeni eliphezulu, futhi i-voltage engu-5V kumele ifakwe ekugcineni "kokuguqula" ukuze kukhiqizwe ukukhishwa kwamandla e-RF.
3.2 Ukulawulwa kwamandla
Sicela usebenzise i-screwdriver ye-Phillips ukuze ujikelezise i-knob encane ngaphakathi kokuphela "kokuguqulwa kwe-amplitude". Amandla okujikeleza akhuphuka ngokwewashi, kuyilapho amandla okujikeleza akhuphuka ngokwewashi. Qaphela ukuthi isiqondiso sokulungisa amandla sale modeli siphambene nohlobo lokuxhuma oluphezulu lwe-fiber coupling!
