Umugqa wokulibaziseka we-Fiber optic osuselwe ekushintsheni kokubona

Isimiso somugqa wokulibaziseka we-Fiber optic

Ekucutshungulweni kwesignali ye-optical, i-optical fiber ingabona imisebenzi yokulibaziseka kwesignali, ukunwetshwa, ukuphazamiseka, njll. Ukusetshenziswa okuphusile kwale misebenzi kungabona ukucutshungulwa kolwazi kunkambu ye-aptical yonke. Phakathi kwazo, umsebenzi wokulibaziseka we-Fiber optical ungenziwa umugqa wokulibaziseka we-Fiber optic, uthatha i-fiber optical yemodi eyodwa evamile njengesibonelo, lapho ukudluliswa kwesignali ye-optical yokusebenza kwe-wavelength ye-1550nm, ukudluliswa kwamamitha angu-200 kungafinyelela ukubambezeleka kwe-1μs, futhi ukulahlekelwa kokufaka okuhambisanayo ku-04B kuphela. Uma kuqhathaniswa, ukulahlekelwa kokufaka okubangelwa ulayini wokulibaziseka we-microwave ovamile yinqwaba ye-dB, futhi ulayini wokulibaziseka we-fiber optical wehlisa ukulahlekelwa kokufaka cishe ngama-oda angu-2 obukhulu, okuthuthukisa kakhulu ukuncintisana kolayini wokulibaziseka we-Fiber optic. Ngaphezu kwalokho, i-Fiberumugqa wokulibaziseka we-opticfuthi ibe nezici zosayizi omncane, isisindo esilula, umkhiqizo omkhulu wokubambezeleka komkhawulokudonsa, ikhono eliqinile lokuphazanyiswa kwe-anti-electromagnetic, futhi ube imbangi eqinile yemigqa yokulibaziseka ye-microwave, futhi ingashintsha ngokuphelele imigqa yokulibaziseka ye-microwave emikhakheni eminingi. Uma kuqhathaniswa nomugqa wokulibaziseka we-microwave ovamile, umugqa wokulibaziseka we-fiber optical unomkhiqizo womkhawulokudonsa wesikhathi esiphezulu, obonisa ukuthi uhlelo lunokulungiswa okuhle kokulinganisa imvamisa, ukuzwela okuphezulu nekhono lokunqamula isignali ephezulu, futhi lingahlangabezana nezidingo zezinhlelo ze-radar zokuxazulula okuphezulu njengemigqa yokulibaziseka. Futhi imvamisa yokusebenza ye-FDL iphezulu kakhulu, ingaba phezulu kakhulu kune-100GHz, uma kuqhathaniswa nomugqa wokulibaziseka kwegagasi le-acoustic wamakhulukhulu we-megahertz yokusebenza imvamisa kanye nomugqa wokulibaziseka we-CCD wamashumi ama-megahertz imvamisa yokusebenza uma kuqhathaniswa nama-oda amaningana wobukhulu, futhi ngokusekelwe ku-radar yokuxhumana yesikhathi esizayo nezinye izinhlelo zizoshintsha kumkhuba we-band frequency high, i-FDL iyinzuzo ephawulekayo; Ngaphezu kwalokho, ulayini wokulibaziseka we-fiber nawo unesici sokuthi ukulahleka kokubambezeleka kweyunithi kuzimele kufrikhwensi. Izinzuzo eziyingqayizivele zale migqa yokulibaziseka ye-fiber optic ngokungangabazeki ifakazela amandla ayo ekucubunguleni isignali.

Ukusetshenziswa komugqa wokulibaziseka we-Fiber optic

Umsebenzi oyisisekelo womugqa wokulibaziseka we-Fiber optic uwukubambezela isignali, engakwazi ukubona umsebenzi wesitoreji esibona konke kanye nokulingana kweshifti ngokusebenzisa ukubambezeleka, futhi inohlu olubanzi lwezinhlelo zokusebenza ku-radar yohlelo olunezigaba, isistimu yokuxhumana ye-fiber optical, uhlelo lwekhompiyutha optical kanye nezinyathelo eziphikisana ne-elekthronikhi. Ku-radar yohlelo olunezigaba, i-antenna yohlu olunezigaba luyingxenye eyinhloko, umsebenzi oyinhloko wothiyo lohlu olunezigaba ukushintsha umsebenzi wephethini womugqa ohlanganisiwe, ukuze kuzuzwe ushintsho lomumo we-antenna ye-antenna kanye nokuskena okusheshayo kwe-beam, futhi lo msebenzi ufinyelelwa ngokulawula i-amplitude kanye nolwazi lwesigaba se-indipenna iyunithi yesignali. Uma kuqhathaniswa nolayini wokulibaziseka we-microwave, i-FDL inomkhawulokudonsa omkhulu, futhi ayikho inkinga yokutsheka kwe-beam. Ku-antenna yesigaba esilawulwa ngokubonakalayo, i-FDL ingabona ukwabiwa kwesigaba okunembile nokulawula isignali ye-microwave futhi isuse umsindo ohlobene wesignali ye-echo, ukuze i-FDL ibe inketho engcono kakhulu ku-antenna yohlu olunezigaba. Kusifanisi sethagethi ye-radar, i-FDL isetshenziselwa ukulingisa amasiginali amabanga ahlukene. Ngezimfuneko zesistimu ye-radar yesimanje yesifanisi sethagethi ye-radar, njengebhendi yemvamisa ephezulu, isivinini sokushintsha okuqondiwe okusheshayo kanye nebanga elide lokulingisa okuqondiwe, imigqa yokulibaziseka evamile ibikude kakhulu nokuhlangabezana nezidingo zesistimu ye-radar, ngakho-ke umugqa wokulibaziseka we-fiber optic usuphenduke umugqa wokulibaziseka kuphela osebenzayo. Ngaphezu kwalokhu okungenhla, ohlelweni lokuxhumana lwe-fiber optical, i-FDL ingakwazi futhi ukubona umsebenzi wokufaka ikhodi yesignali kanye nokugcinwa kwesikhashana. Kafushane, kungabonakala ukuthi ulayini wokulibaziseka we-fiber optic unezinhlelo zokusebenza ezibalulekile kanye nesimo esingabuyiseleki emikhakheni eminingi, ngakho-ke ukucwaninga komugqa wokulibaziseka we-fiber optic osebenza kakhulu unokubaluleka okukhulu kwesayensi ekusetshenzisweni kwe-fiber optic.ubuchwepheshe be-microwave photon.

Idizayini yomugqa wokulibaziseka we-Fiber optic

Ulayini wokulibaziseka we-fiber optic osuselwe ekushintsheni kokubonayo ukhetha izindlela ezihlukile zokubona ukuze kuzuzwe ukubambezeleka kwesikhathi esihlukile ngokusebenzisa iswishi yokubona. Umgomo oyisisekelo walolu hlobo lohlelo ukuzuza ukubambezeleka okuhlukile ngokushintsha indlela yokubona. Kuwumugqa wokulibaziseka ojwayelekile we-Fiber optic ojwayelekile, futhi ukwakheka kwawo okujwayelekile kuboniswa esithombeni.

 

Ngemuva kokuthi isignali ye-optical eshintshiwe idluliselwe nge-fiber optical, indlela yokubona eyenza ukubambezeleka okuhambisanayo ikhethwa yi-optical switch array, futhi ukubambezeleka okudingekayo kungafinyelelwa ngokuvula iswishi ye-optical nokuqinisekisa ukuthi amanye ama-optical switch avaliwe. Inzuzo yalolu hlobo lomugqa wokulibaziseka we-fiber optical ukuthi ingafinyelela ukubambezeleka okukhulu, indlela yokuqaphela ilula, futhi izici ezihambisanayo zihlukile ngokuvumelana nokukhethwa kokushintsha okuhlukile kwe-optical.
