Matanho ekushanda kwemodulator ye acousto-optic yenzvimbo yakasununguka
Nzvimbo yakasunungukamodulator yeacousto-opticzvinopinda uye zvinoburitsa mwenje kuburikidza nemaburi echiedza akavhurika, zvichida kurongeka kwakanyatsojeka uye kugadziriswa kwekona yeBragg nefuremu yekugadzirisa ine mativi matatu. Zvichienzaniswa nefiber coupling series, free space series inoda matanho ekuwedzera ekugadzirisa nzira ye optical, asi ine zvakanakira zvakaita senzira dze optical dzinochinjika uye kutarisa kwenzvimbo dze diffraction.

1. Matanho ekuisa uye kugadzirisa ese ari maviri e "acousto-optic modulator series"
Kuiswa nekugadzirisa modulator yemahara acousto-optic inhanho dzinoshandiswa kakawanda kune mamodheru maviri, seizvi:
Danho 1: Mushure mekunge zvishandiso zvese zvekunze nemaseketi zvabatanidzwa, gadzirisa mudziyo weacousto-optic pafuremu yekugadzirisa ine mativi matatu, gadzirisa kukwirira kwemudziyo weacousto-optic kumusoro nekudzika kuti mwenje welaser upfuure nenzvimbo yakakodzera yemudziyo weacousto-optic. Cherechedza: Nzvimbo yakakodzera yekuvhenekesa iri pakati peukobvu hwekristaro, uye 1.5mm kure neelectrode yegoridhe usati wadzvanya uye wapedza kudzvanya.
Danho rechipiri: Batidza magetsi e24V woisa chiratidzo (zvinokurudzirwa kuti chiratidzo chirambe chiri pa5V paunenge uchigadzirisa simba re diffraction, kuitira kuti simba rekutyaira rirambe richishanda). Gadzirisa kona yeBragg yemudziyo weacousto-optickuruboshwe nerudyi kuti uwane simba repamusoro rekupararira kwenzwi rekutanga.
Danho rechitatu: Mushure mekugadzirisa chiedza chekutanga che diffraction che acousto-optic device, chero chiratidzo chinogona kuiswa zvichienderana nezvinodiwa zvekuyedza.
2 0~5V rudzi (nzvimbo yakasununguka)
2.1 Tsananguro yeChiratidzo cheKuchinja
Chiteshi che "0-5V" chinoshandiswa kurodha masaini ekudzora uye chiratidzo che analog che 0-5V. Dzima kana voltage yekupinda iri 0V, uye simba reRF rinobuda rasvika pakakwirira kana voltage yekupinda iri 5V. Nzira yekushandura modhi iyi yakafanana ne "0-5V analog type" yefiber yakabatana, asi chimiro che optical path chakasiyana, chinoda mamwe matanho ekuisa nekugadzirisa.
2.2 Nzira yekubatanidza
"RF" yesimba rekufambisa ndiyo RF power output port. Ndapota isanganisei neBNC signal line inoenderana, uye rimwe divi resignal line rinofanira kubatanidzwa zvakananga kune ruzha nelight device neBNC. Zivai kuti modhi iyi inoshandisa BNC interface, iyo yakasiyana neSMA interface yemamodheru mazhinji ekubatanidza fiber.
2.3 Kudzora simba
Ndapota shandisa sikurudhiraivha yePhillips kutenderedza pfundo diki riri padivi. Simba rekutenderera rinoenderera newachi rinowedzera, ukuwo simba rekutenderera rinoenderera newachi richiderera. Ndapota cherechedzai kuti pfundo rekugadzirisa simba remuenzaniso uyu riri paburi diki padivi, iro rakasiyana nechiteshi che "amplitude modulation" chemamwe mamodheru.
3 Rudzi rwekufambisa dhiraivha yepamusoro (nzvimbo yakasununguka)
3.1 Tsananguro yeChiratidzo cheKuchinja
Chiteshi che'modulation' chinoshandiswa kurodha masaini ekudzora uye chiratidzo chedhijitari cheTTL chakajairwa. Simba riri kutenderera padanho repamusoro, uye voltage ye5V inofanira kuiswa pa "modulation" terminal kuti ibudise RF power output. Kana modulation terminal iri padanho repasi, RF output inodzimwa. Hunhu hwe modulation hwemuenzaniso uyu hwakafanana ne "high-level conduction type" ye fiber coupling, asi chimiro che optical path chakasiyana, chinoda mamwe matanho ekuisa nekugadzirisa. Cherechedza: Simba riri kutenderera padanho repamusoro, uye voltage ye5V inofanira kuiswa padanho re "modulation" kuti ibudise RF power output.
3.2 Kudzora simba
Ndokumbirawo mushandise sikurudhiraivha yePhillips kuti mutenderedze gomba diki riri mukati me "amplitude modulation". Simba rekutenderera rinoenderera newachi rinowedzera, ukuwo simba rekutenderera rinoenderera newachi richiderera. Cherechedzai kuti nzira yekugadzirisa simba remuenzaniso uyu yakasiyana nerudzi rwepamusoro rwe coupling yefiber!
