Yintoni iFiber Optic Delay Line OFDL

I-Fiber Optical Delay Line (OFDL) sisixhobo esinokufikelela ukulibaziseka kwexesha leempawu ze-optical. Ngokusebenzisa ukulibaziseka, inokufezekisa ukutshintshwa kwesigaba, ukugcinwa kwezinto zonke kunye neminye imisebenzi. Inoluhlu olubanzi lwezicelo kwi-radar yoluhlu olunezigaba, iisistim zonxibelelwano lwefiber optic, imilinganiselo yokumelana ne-elektroniki, uphando lwezenzululwazi kunye novavanyo, kunye nezinye iinkalo. Eli nqaku liza kuqala kwimigaqo esisiseko yemigca yokulibazisa i-fiber optic, igxininise kwiimeko zesicelo kunye nendlela yokukhetha umgca wokulibazisa i-fiber optic efanelekileyo.
Umgaqo wokusebenza
Umgaqo osisiseko we-fiber optic umgca wokulibaziseka kukuba isibonakaliso se-optical sokulibaziseka sithunyelwa ngobude obuthile bentambo ye-fiber optic, kwaye ngenxa yexesha elifunekayo ukuhanjiswa kokukhanya kwintambo ye-fiber optic, ukulibaziseka kwexesha lomqondiso we-optical kufezekiswa. Njengoko kuboniswe kwi-Figure 1, umgca wokulibaziseka we-fiber optic olula yinkqubo eyenziwe ngezixhobo ezifana ne-lasers, i-modulators, iifayili zokuhambisa, kunye ne-photodetectors kunye nomsebenzi wokulibaziseka komqondiso. Umgaqo osebenzayo: Umqondiso weRF oza kuhanjiswa kunye nesignali ye-optical ekhutshwa yilaser ifakwe kwiimodyuli ezahlukeneyo. Iimodyuli zimodareyitha umqondiso weRF ekukhanyeni ukwenza umqondiso obonakalayo ophethe ulwazi lweRF. Isignali yokukhanya ephethe ulwazi lweRF idityaniswa nefayibha optic ilinki ukuze isasazeke, ilibazisekile ixesha elithile, ize ifike kwisixhobo sokufota. Isihloli sefoto siguqula umqondiso ofunyenweyo ophethe iinkcukacha zeRF zibe yimveliso yombane.

Iimeko zesicelo
1.I-radar yoluhlu oluyinqanaba: Inxalenye ephambili ye-radar yoluhlu olunezigaba yi-eriyali yoluhlu olunezigaba. Ii-antenna ze-radar zemveli zikude ukuhlangabezana neemfuno zeenkqubo ze-radar, ngelixa imigca yokulibaziseka ye-fiber optic ineenzuzo zabo zokusebenza ezizodwa ekusetyenzisweni kwee-eriyali ezihleliweyo. Ke ngoko, imigca yokulibaziseka yefiber optic inokubaluleka okubalulekileyo kwezesayensi kwirada yoluhlu olunezigaba.
I-2.Inkqubo yokunxibelelana kwe-Fiber optic: Imigca yokulibaziseka ye-Fiber optic ingasetyenziselwa ukuphumeza izikimu ezithile ze-encoding. Ngokuzisa ukulibaziseka okuhlukeneyo ngamaxesha ahlukeneyo, iimpawu ze-encoding kunye neepatheni ezithile zinokwenziwa, okunenzuzo ekuphuculeni ukukwazi ukuchasana nokuphazanyiswa kweempawu kwiinkqubo zonxibelelwano lwedijithali. Ukongeza, inokusetyenziswa njengokugcinwa kwesikhashana (i-cache) ukugcina idatha ethile okwethutyana, njalo njalo. Ngamafutshane, imigca yokulibaziseka ye-fiber optic inoluhlu olubanzi lwezicelo kwiindawo ezininzi ngenxa ye-bandwidth ephezulu, ilahleko ephantsi, kunye nokuchasana nokuphazamiseka kwe-electromagnetic. Enoba kumacandelo onxibelelwano, iradar, ukuhamba ngenqanawa, okanye umfanekiso wezonyango, zonke zidlala indima ebalulekileyo.
