Tallaabooyinka hawlgalkamodulator-ka acousto-optic-ga booska xorta ah
Meesha bannaanmodulator-ka acousto-opticwaxay soo saartaa iftiinka iftiinka iyada oo loo marayo godadka iftiinka furan, taasoo u baahan iswaafajin sax ah iyo hagaajin xagal Bragg ah oo leh qaab-dhismeed saddex-cabbir ah. Marka la barbardhigo taxanaha isku xidhka fiilooyinka, taxanaha booska xorta ah wuxuu u baahan yahay tallaabooyin hagaajin waddo oo dheeraad ah, laakiin wuxuu leeyahay faa'iidooyin sida waddooyinka indhaha ee dabacsan iyo indha-indheynta dareen leh ee meelaha kala-baxa.
1. Tallaabooyinka rakibaadda iyo hagaajinta guud ee loogu talagalay taxanaha modulator-ka acousto-optic ee booska bilaashka ah
Rakibaadda iyo hagaajinta modulator-ka booska xorta ah ee acousto-optic waa tallaabooyin caadi ah oo loogu talagalay laba nooc, sida soo socota:
Tallaabada 1: Ka dib marka dhammaan aaladaha dibadda iyo wareegyada la isku xiro, qalabka acousto-optic ku hagaaji qaab-dhismeedka saddex-geesoodka ah, hagaaji dhererka qalabka acousto-optic-ga kor iyo hoos si aad u oggolaato in iftiinka laysarka uu dhex maro booska ugu habboon ee qalabka acousto-optic-ga. Fiiro gaar ah: Meesha ugu habboon ee iftiimintu waa bartamaha dhumucda kiristaalka, iyo 1.5mm meel u jirta elektroodka dahabka ah ka hor iyo ka dib riixista.
Tallaabada 2: Daar korontada 24V oo ku shub calaamadda (waxaa lagugula talinayaa inaad calaamadda ku hayso 5V marka aad hagaajinayso xoogga kala-baxa, si korontada wadista ay u sii shaqeyso). Hagaaji xagasha Bragg eeqalabka acousto-opticalbidix iyo midig si loo gaaro xoojinta kala-soocidda heerka koowaad ee ugu sarreysa.
Tallaabada 3aad: Ka dib marka la hagaajiyo iftiinka kala-soocidda ee nidaamka koowaad ee qalabka acousto-optic, calaamad kasta waa la rari karaa iyadoo loo eegayo shuruudaha tijaabada.
Nooca 2 0 ~ 5V (meel bannaan)
2.1 Sharaxaadda Calaamadaha Wax-ka-beddelka
Dekedda "0-5V" waxaa loo isticmaalaa in lagu raro calaamadaha xakamaynta waana calaamad analog ah oo ah 0-5V. Dami marka danabka la gelinayo uu yahay 0V, awoodda wax soo saarka RF-na ay gaarto ugu badnaan marka danabka la gelinayo uu yahay 5V. Habka wax ka beddelka ee qaabkan asal ahaan waa isku mid sida nooca fiilada ee isku xiran "nooca analogga ah ee 0-5V", laakiin qaab-dhismeedka wadada indhaha waa ka duwan yahay, taasoo u baahan rakibid dheeraad ah iyo tallaabooyin hagaajin ah.
2.2 Habka isku xirka
"RF" ee korontada wadista waa dekedda soo saarista korontada RF. Fadlan ku xidh khadka calaamadda BNC ee isku midka ah, dhammaadka kale ee xariiqda calaamadda waa in si toos ah loogu xidhaa qalabka codka iyo iftiinka ee leh BNC. Ogsoonow in qaabkani uu isticmaalo is-dhexgalka BNC, kaas oo ka duwan is-dhexgalka SMA ee moodooyinka isku xidhka fiilooyinka badankood.
2.3 Xakamaynta Awoodda
Fadlan isticmaal kaashawiito Phillips ah si aad u wareejiso badhanka godka yar ee dhinaca. Awoodda wareegga saacadda ayaa kordheysa, halka awoodda wareegga ee ka soo horjeedda saacadda ay hoos u dhacayso. Fadlan ogow in badhanka hagaajinta awoodda ee qaabkan uu ku yaal god yar oo dhinaca ah, kaas oo ka duwan dekedda "modulation of amplitude" ee moodooyinka kale.
3 Nooca gudbiyaha heerka sare ah (meel bannaan)
3.1 Sharaxaadda Calaamadaha Wax-ka-beddelka
Dekedda 'isbeddelka' waxaa loo isticmaalaa in lagu raro calaamadaha xakamaynta waana calaamad dijitaal ah oo TTL caadi ah. Korontadu waxay ku socotaa heer sare, danab 5V ahna waa in lagu dabaqaa terminaalka "isbeddelka" si loo soo saaro wax soo saarka korontada RF. Marka terminaalka isbeddelka uu joogo heer hoose, wax soo saarka RF waa la damiyaa. Astaamaha isbeddelka ee qaabkan waxay la mid yihiin "nooca isdhaafka heerka sare ah" ee isku xirka fiilada, laakiin qaab-dhismeedka wadada indhaha waa ka duwan yahay, taasoo u baahan rakibid dheeraad ah iyo tallaabooyin hagaajin. Fiiro gaar ah: Korontadu waxay ku socotaa heer sare, danab 5V waa in lagu dabaqaa dhammaadka "isbeddelka" si loo soo saaro wax soo saarka korontada RF.
3.2 Xakamaynta Awoodda
Fadlan isticmaal kaashawiito Phillips ah si aad u wareejiso badhanka godka yar ee ku jira dhammaadka "modulation-ka baaxadda leh". Awoodda wareegga saacadda ayaa kordheysa, halka awoodda wareegga ee ka soo horjeedda saacadda ay hoos u dhacayso. Ogsoonow in jihada hagaajinta awoodda ee qaabkani ay ka soo horjeeddo nooca gudbinta heerka sare ee isku xirka fiilada!
