Njira zogwirira ntchito za acousto-optic modulator ya malo opanda kanthu

Njira zogwirira ntchito zamodulator ya acousto-optic ya malo aulere
Malo auleremodulator ya acousto-opticZolowetsa ndi kutulutsa kuwala kudzera m'mabowo otseguka a kuwala, zomwe zimafuna kulinganiza bwino komanso kusintha kwa ngodya ya Bragg ndi chimango chosinthira cha magawo atatu. Poyerekeza ndi mndandanda wolumikizira ulusi, mndandanda wa malo omasuka umafuna njira zina zosinthira njira ya kuwala, koma uli ndi zabwino monga njira zosinthika za kuwala ndi kuwona mwachidwi malo owonekera.

1. Njira zokhazikitsira ndi kusintha zonse kuti pakhale malo opanda kanthu acousto-optic modulator series
Kukhazikitsa ndi kusintha kwa modulator ya acousto-optic ya malo opanda kanthu ndi njira zodziwika bwino zogwirira ntchito pa mitundu iwiri, motere:
Gawo 1: Zipangizo zonse zakunja ndi ma circuits atalumikizidwa, konzani chipangizo cha acousto-optic pa chimango chosinthira cha magawo atatu, sinthani kutalika kwa chipangizo cha acousto-optic mmwamba ndi pansi kuti kuwala kwa laser kudutse pamalo abwino kwambiri a chipangizo cha acousto-optic. Dziwani: Malo abwino kwambiri owunikira ali pakati pa makulidwe a kristalo, ndipo 1.5mm kutali ndi electrode yagolide musanakanikize komanso mutakanikiza.
Gawo 2: Yatsani magetsi a 24V ndikuyika chizindikiro (ndibwino kuti chizindikirocho chikhale pa 5V mukakonza mphamvu ya diffraction, kuti magetsi oyendetsa apitirize kugwira ntchito). Sinthani ngodya ya Bragg yachipangizo cha acousto-optickumanzere ndi kumanja kuti mupeze mphamvu yapamwamba kwambiri ya diffraction yoyamba.
Gawo 3: Mukasintha kuwala koyambira kwa diffraction ya chipangizo cha acousto-optic, chizindikiro chilichonse chikhoza kuyikidwa malinga ndi zofunikira zoyesera.
Mtundu wa 2 0~5V (malo opanda kanthu)
2.1 Kufotokozera kwa Chizindikiro cha Kusintha
Doko la "0-5V" limagwiritsidwa ntchito poyika zizindikiro zowongolera ndipo ndi chizindikiro cha analogi cha 0-5V. Zimitsani pamene voteji yolowera ndi 0V, ndipo mphamvu yotulutsa ya RF ifika pachimake pamene voteji yolowera ndi 5V. Njira yosinthira ya chitsanzo ichi ndi yofanana ndi "mtundu wa analogi wa 0-5V" wolumikizidwa ndi ulusi, koma kapangidwe ka njira yowunikira ndi kosiyana, komwe kumafuna njira zowonjezera zoyikira ndi kusintha.
2.2 Njira yolumikizira
"RF" ya magetsi oyendetsera ndi doko lotulutsa mphamvu la RF. Chonde ilumikizeni ndi mzere wofanana wa chizindikiro cha BNC, ndipo mbali ina ya mzere wa chizindikiro iyenera kulumikizidwa mwachindunji ku chipangizo cha mawu ndi kuwala ndi BNC. Dziwani kuti chitsanzo ichi chimagwiritsa ntchito mawonekedwe a BNC, omwe ndi osiyana ndi mawonekedwe a SMA a mitundu yambiri yolumikizira ulusi.
2.3 Kulamulira mphamvu
Chonde gwiritsani ntchito screwdriver ya Phillips kuti muzungulire chogwirira chaching'ono chomwe chili m'mbali. Mphamvu yozungulira mozungulira imawonjezeka, pomwe mphamvu yozungulira mozungulira mozungulira imachepa. Dziwani kuti chogwirira chosinthira mphamvu cha chitsanzo ichi chili pa dzenje laling'ono m'mbali, lomwe ndi losiyana ndi doko la "amplitude modulation" la mitundu ina.
3 Mtundu wapamwamba wa conductive (malo opanda kanthu)
3.1 Kufotokozera kwa Chizindikiro cha Modulation
Doko la 'modulation' limagwiritsidwa ntchito poika zizindikiro zowongolera ndipo ndi chizindikiro cha digito cha TTL. Mphamvu ikuyenda pamlingo wapamwamba, ndipo magetsi a 5V ayenera kugwiritsidwa ntchito ku "modulation" terminal kuti apange mphamvu ya RF. Pamene modulation terminal ili pamlingo wotsika, RF output imazimitsidwa. Makhalidwe a modulation a chitsanzochi ndi ofanana ndi "mtundu wapamwamba wa conduction" wa fiber coupling, koma kapangidwe ka njira ya kuwala ndi kosiyana, komwe kumafuna njira zowonjezera zoyikira ndi kusintha. Dziwani: Mphamvu ikuyenda pamlingo wapamwamba, ndipo magetsi a 5V ayenera kugwiritsidwa ntchito kumapeto kwa "modulation" kuti apange mphamvu ya RF output.
3.2 Kulamulira mphamvu
Chonde gwiritsani ntchito screwdriver ya Phillips kuti muzungulire kabokosi kakang'ono ka dzenje mkati mwa "amplitude modulation". Mphamvu yozungulira mozungulira mozungulira imawonjezeka, pomwe mphamvu yozungulira mozungulira mozungulira imachepa. Dziwani kuti njira yosinthira mphamvu ya chitsanzo ichi ndi yosiyana ndi mtundu wapamwamba wa coupling wa ulusi!
