Ishishini lonxibelelwano nge-laser likhula ngokukhawuleza kwaye liza kungena kwixesha legolide lophuhliso
Unxibelelwano lweLaser luhlobo lwendlela yonxibelelwano esebenzisa i-laser ukuhambisa ulwazi.I-Laser luhlobo olutsha lweumthombo wokukhanya, eneempawu zokukhanya okuphezulu, ukuqondisa okuqinileyo, i-monochromism enhle kunye nokuhambelana okuqinileyo.Ngokwendlela eyahlukileyo yothumelo, inokwahlulwa ibe yi-atmosphericlaser unxibelelwanokunye nonxibelelwano lwefiber optical.Unxibelelwano ngelaser ye-atmospheric lunxibelelwano lwelaser kusetyenziswa iatmosphere njengendlela yothumelo.Unxibelelwano lwefiber optical yindlela yonxibelelwano isebenzisa ifayibha yamehlo ukuhambisa imiqondiso yamehlo.
Inkqubo yonxibelelwano nge-laser inamacandelo amabini: ukuthumela nokwamkela.Inxalenye yothutho ikakhulu ibandakanya i-laser, imodyuli ye-Optical kunye ne-eriyali yokudlulisa amehlo.Inxalenye yokufumana ikakhulu ibandakanya i-eriyali yokufumana i-optical, i-optical filter kunyeIsikhangeli seefoto.Ulwazi oluya kuhanjiswa luthunyelwa kuImodyuli yokukhanyaeqhagamshelwe kwi-laser, ehlengahlengisa ulwazi kwilaserkwaye iyithumele ngaphandle nge-eriyali yokudlulisa amehlo.Ekupheleni kokufumana, i-antenna yokufumana i-optical ifumana isignali ye-laser kwaye iyithumele kwiumtshina wamehlo, eguqula isignali ye-laser ibe ngumqondiso wombane kwaye iguqule ibe yinkcazelo yokuqala emva kokukhulisa kunye nokunciphisa.
Isathelayithi nganye kuthungelwano lwesathelayithi yothungelwano olucetyiweyo lweMesh inokuba namakhonkco e-laser afikelela kuma mane ukuze bakwazi ukunxibelelana nezinye iisathelayithi, iinqwelomoya, iinqanawa kunye nezikhululo ezisemhlabeni.Amakhonkco okubonaphakathi kwesathelayithi zibalulekile kwimpumelelo yomkhosi wase-US ophantsi kwe-Earth orbit constellation, eya kusetyenziselwa unxibelelwano lwedatha phakathi kweeplanethi ezininzi.IiLasers zinokubonelela ngamazinga aphezulu othumelo lwedatha kunonxibelelwano lweRF yemveli, kodwa zikwabiza kakhulu.
Umkhosi wase-US usanda kunikezela malunga ne-1.8 yeebhiliyoni zeedola kwiikontraka zenkqubo ye-126 Constellation ukuba yakhiwe ngokwahlukileyo ziinkampani zase-US eziphuhlise itekhnoloji yonxibelelwano ye-one-to-many optical yokuhanjiswa kwe-point-to-multipoint enokunceda ukunciphisa indleko yokwakha. iinkwenkwezi ngokunciphisa kakhulu imfuno yeetheminali.Uxhulumaniso olunye ukuya kwabaninzi luphunyezwa sisixhobo esibizwa ngokuba lulawulo olululo lwe-optical communication array (i-MOCA ngokufutshane), eyohlukileyo kuba inemodyuli kakhulu, kwaye i-MOCA elawulwa yi-optical communication array yenza i-optical inter-satellite links ukunxibelelana nayo. ezinye iisatellite ezininzi.Kunxibelelwano lwe-laser yendabuko, yonke into ikhomba-inqaku, ubudlelwane obunye.Nge-MOCA, i-inter-satellite optical link inokuthetha neesathelayithi ezingama-40 ezahlukeneyo.Le teknoloji ayikho nje inzuzo yokunciphisa iindleko zokwakha i-satellite constellations, ukuba iindleko ze-nodes ziyancipha, kukho ithuba lokuphumeza i-architectures ezahlukeneyo zenethiwekhi kwaye ngaloo ndlela amanqanaba eenkonzo ezahlukeneyo.
Ngexesha elidlulileyo, i-satellite ye-Beidou yase-China yenza uvavanyo lonxibelelwano lwe-laser, yadlulisela ngempumelelo umqondiso ngendlela ye-laser kwisikhululo sokwamkela umhlaba, obaluleke kakhulu kunxibelelwano olukhawulezayo phakathi kothungelwano lwesathelayithi kwixesha elizayo, ukusetyenziswa kwelaser. unxibelelwano lunokuvumela isathelayithi ukuba idlulise amawaka eemegabhithi zedatha ngomzuzwana, isantya sokhuphelo sobomi bethu bemihla ngemihla ziimegabhibhithi ezimbalwa ukuya kwishumi leemegabhithi ngomzuzwana, kwaye emva kokuba unxibelelwano lwelaser lufezekisiwe, Ukukhuphela isantya kunokufikelela kwiigigabytes ezininzi ngomzuzwana, nakwixesha elizayo. inokuphuhliswa ibe ziiterabytes.
Okwangoku, inkqubo yokukhangela yase-China yase-Beidou isayine izivumelwano zentsebenziswano kunye namazwe angama-137 kwihlabathi jikelele, inempembelelo ethile kwihlabathi, kwaye iya kuqhubeka nokwandisa kwixesha elizayo, nangona inkqubo yokukhangela yase-China ye-Beidou iseti yesithathu yenkqubo yokukhangela i-satellite eqolileyo, kodwa inelona nani likhulu leisathelayithi, nangaphezu kwenani lesathelayithi zenkqubo yeGPS.Okwangoku, inkqubo yokukhangela ye-Beidou idlala indima ebalulekileyo kwibala lomkhosi nakwibala labemi.Ukuba unxibelelwano lwelaser lunokuphunyezwa, luya kuzisa iindaba ezilungileyo kwihlabathi.
