Amanyathelo okusebenzai-modulator ye-acousto-optic yendawo ekhululekileyo
Indawo yasimahlai-modulator ye-acousto-opticIgalelo kunye nokukhupha imitha yokukhanya ngemingxuma yokukhanya evulekileyo, efuna ulungelelwaniso oluchanekileyo kunye nohlengahlengiso lwe-engile yeBragg enesakhelo sohlengahlengiso olunemilinganiselo emithathu. Xa kuthelekiswa nochungechunge lwe-fiber coupling, uthotho lwesithuba sasimahla lufuna amanyathelo ongezelelweyo ohlengahlengiso lwendlela ye-optical, kodwa luneengenelo ezifana neendlela ze-optical eziguquguqukayo kunye nokujonga ngokubonakalayo iindawo ze-diffraction.
1. Amanyathelo okufakela kunye nokulungisa i-acousto-optic modulator series yesithuba sasimahla
Ukufakelwa kunye nokulungiswa kwe-free space acousto-optic modulator ngamanyathelo aqhelekileyo okusebenza kwiimodeli ezimbini, ngolu hlobo lulandelayo:
Inyathelo 1: Emva kokuba zonke izixhobo zangaphandle kunye neesekethe ziqhagamshelwe, lungisa isixhobo se-acousto-optic kwisakhelo sohlengahlengiso esinemilinganiselo emithathu, lungisa ukuphakama kwesixhobo se-acousto-optic phezulu nasezantsi ukuze uvumele umqadi welaser udlule kwindawo efanelekileyo yesixhobo se-acousto-optic. Qaphela: Indawo efanelekileyo yokukhanyisa iphakathi kobukhulu bekristale, kwaye ikude nge-1.5mm ukusuka kwi-electrode yegolide ngaphambi nasemva kokucinezela.
Inyathelo lesi-2: Vula umbane we-24V uze ulayishe isignali (kucetyiswa ukuba isignali igcinwe kwi-5V xa ulungisa i-diffraction intensity, ukuze umbane oqhubayo uqhubeke nokusebenza). Lungisa i-engile yeBragg yeisixhobo se-acousto-opticekhohlo nasekunene ukuze kufumaneke ubunzulu obuphezulu bokuphambuka komgca wokuqala.
Inyathelo lesi-3: Emva kokulungisa isibane sokukhanya kwe-diffraction ye-oda yokuqala yesixhobo se-acousto-optic, naluphi na uphawu lungalayishwa ngokweemfuno zovavanyo.
Uhlobo lwe-2 0~5V (indawo yasimahla)
2.1 Inkcazo yeSignali yoGuquguquko
I-“0-5V” port isetyenziselwa ukulayisha imiqondiso yokulawula kwaye sisignali ye-analog ye-0-5V. Cima xa i-voltage yokufaka i-0V, kwaye amandla okukhupha e-RF afikelela kwi-high yayo xa i-voltage yokufaka i-5V. Indlela yokuguqula yale modeli ifana kakhulu ne-“0-5V analog type” edityanisiweyo yefayibha, kodwa ulwakhiwo lwendlela ye-optical lwahlukile, lufuna amanyathelo ongezelelweyo okufakela kunye nokulungisa.
2.2 Indlela yoqhagamshelo
I-“RF” yombane oqhubayo sisibuko sokuphuma kwamandla se-RF. Nceda uyiqhagamshele kumgca wesignali ye-BNC ohambelanayo, kwaye elinye icala lomgca wesignali kufuneka liqhagamshelwe ngqo kwisixhobo sesandi nesibane esine-BNC. Qaphela ukuba le modeli isebenzisa ujongano lwe-BNC, olwahlukileyo kujongano lwe-SMA lweemodeli ezininzi zokudibanisa ifayibha.
2.3 Ulawulo lwamandla
Nceda sebenzisa i-screwdriver yePhillips ukuze ujikelezise iqhina elincinci elinomngxuma ecaleni. Amandla okujikeleza ngokwewotshi ayanda, ngelixa amandla okujikeleza ngokwewotshi ehla. Nceda uqaphele ukuba iqhina lokulungisa amandla lale modeli likwimngxuma omncinci ecaleni, eyahlukileyo kwi-port "ye-amplitude modulation" yezinye iimodeli.
3 Uhlobo lokuhambisa oluphezulu (indawo ekhululekileyo)
3.1 Inkcazo yeSignali yoGuquguquko
I-'modulation' port isetyenziselwa ukulayisha imiqondiso yokulawula kwaye yisignali yedijithali eqhelekileyo ye-TTL. Umbane uqhuba kwinqanaba eliphezulu, kwaye kufuneka kufakwe i-voltage ye-5V kwi-terminal "ye-modulation" ukuvelisa i-RF power output. Xa i-terminal ye-modulation ikwinqanaba eliphantsi, i-RF output iyacinywa. Iimpawu ze-modulation zale modeli ziyafana "nohlobo lwe-conduction yenqanaba eliphezulu" lwe-fiber coupling, kodwa ulwakhiwo lwendlela ye-optical lwahlukile, lufuna amanyathelo ongezelelweyo okufakelwa kunye nokulungiswa. Qaphela: Umbane uqhuba kwinqanaba eliphezulu, kwaye kufuneka kusetyenziswe i-voltage ye-5V kwisiphelo "se-modulation" ukuvelisa i-RF power output.
3.2 Ulawulo lwamandla
Nceda sebenzisa i-screwdriver yePhillips ukuze ujikelezise iqhosha elincinci elingaphakathi kwesiphelo "sokuguquguquka kwe-amplitude". Amandla okujikeleza ngokwewotshi ayanda, ngelixa amandla okujikeleza ngokwewotshi ehla. Qaphela ukuba indlela yokulungisa amandla yale modeli ichasene nohlobo lokuqhuba oluphezulu lwe-fiber coupling!
