Iyini i-Fiber Optic Delay Line OFDL

I-Fiber Optical Delay Line (OFDL) iyithuluzi elingafinyelela ukulibaziseka kwesikhathi kwamasignali okubona. Ngokusebenzisa ukubambezeleka, ingafinyelela ukuguqulwa kwesigaba, isitoreji esibona konke kanye neminye imisebenzi. Inezinhlobonhlobo zezinhlelo zokusebenza ku-radar yohlelo olunezigaba, izinhlelo zokuxhumana ze-fiber optic, izindlela zokuphikisa zikagesi, ucwaningo lwesayensi nokuhlola, neminye imikhakha. Lesi sihloko sizoqala ngezimiso eziyisisekelo zemigqa yokulibaziseka ye-fiber optic, igxile kuzimo zohlelo lokusebenza kanye nendlela yokukhetha umugqa wokulibaziseka we-fiber optic ofanele.
Isimiso sokusebenza
Isimiso esiyisisekelo somugqa wokulibaziseka we-fiber optic ukuthi isignali ye-optical okufanele ibambezeleke idluliselwa ngobude obuthile bekhebula le-fiber optic, futhi ngenxa yesikhathi esidingekayo ukuze kudluliselwe ukukhanya kukhebula le-fiber optic, ukubambezeleka kwesikhathi kwesignali ye-optical kufinyelelwa. Njengoba kuboniswe kuMfanekiso 1, ulayini olula wokulibaziseka we-fiber optic wuhlelo olwakhiwe ngamadivayisi afana namalaser, ama-modulators, ama-transmission fibers, nama-photodetectors anomsebenzi wokulibaziseka kwesignali. Umgomo wokusebenza: Isiginali ye-RF ezodluliswa kanye nesiginali yokubona ekhishwa i-laser ifakwa kumamoduli ahlukahlukene. Amamoduli ashintsha isignali ye-RF ekukhanyeni ukuze akhe isignali yokubona ephethe ulwazi lwe-RF. Isignali yokubona ephethe ulwazi lwe-RF ihlanganiswe nesixhumanisi se-fiber optic ukuze sidluliselwe, ibambezeleke isikhathi esithile, bese ifinyelela kusithwebuli sezithombe. I-photodetector iguqula isignali yokubona eyamukelwe ephethe ulwazi lwe-RF ibe isignali ephumayo kagesi.

Umfanekiso 1 I-Architecture Eyisisekelo ye-Optic Fiber Delay Line OFDL

Izimo zohlelo lokusebenza
1.I-radar yohlu olunezigaba: Ingxenye eyinhloko ye-radar yohlelo olunezigaba i-antenna yohlu oluhlukaniswe ngezigaba. Ama-antenna e-radar endabuko akude ukuhlangabezana nezidingo zesistimu ye-radar, kuyilapho imigqa yokulibaziseka ye-fiber optic inezinzuzo zayo ezihlukile zokusebenza ekusetshenzisweni kwezimpondo ze-array. Ngakho-ke, imigqa yokulibaziseka ye-fiber optic inokubaluleka okubalulekile kwesayensi ku-radar yohlelo olunezigaba.
I-2.Isistimu yokuxhumana ye-Fiber optic: Imigqa yokulibaziseka ye-Fiber optic ingasetshenziswa ukuze kusetshenziswe izikimu ezithile zokufaka ikhodi. Ngokwethula ukubambezeleka okuhlukene ngezikhathi ezihlukene, amasiginali ombhalo wekhodi anamaphethini athile angakhiqizwa, okuzuzisayo ekuthuthukiseni ikhono lokulwa nokuphazanyiswa lamasignali ezinhlelweni zokuxhumana zedijithali. Ngaphezu kwalokho, ingasetshenziswa futhi njengesitoreji sesikhashana (i-cache) ukugcina idatha ethile okwesikhashana, njalonjalo. Ngamafuphi, imigqa yokulibaziseka ye-fiber optic inohlu olubanzi lwezinhlelo zokusebenza emikhakheni eminingi ngenxa yomkhawulokudonsa wayo ophezulu, ukulahlekelwa okuphansi, nokumelana nokuphazanyiswa yi-electromagnetic. Kungakhathaliseki ukuthi emikhakheni yezokuxhumana, i-radar, i-navigation, noma izithombe zezokwelapha, zonke zidlala indima ebalulekile.
