Indasitiri yekutaurirana nelaser iri kukura nekukurumidza uye yave kuda kupinda munguva yebudiriro
Laser kutaurirana imhando yekutaurirana modhi uchishandisa laser kufambisa ruzivo. Laser rudzi rutsva rwelight source, iyo ine maitiro ekupenya kwepamusoro, kutungamira kwakasimba, monochromism yakanaka uye kubatana kwakasimba. Zvinoenderana neyakasiyana yekufambisa svikiro, inogona kukamurwa kuita mumhepoLaser kutauriranauye optical fiber kutaurirana. Atmospheric laser communication inzira yekutaurirana nelaser ichishandisa mamiriro ekunze senzira yekutapurirana. Optical fiber kutaurirana inzira yekutaurirana uchishandisa optical fiber kutumira masaini masaini.
Iyo laser yekutaurirana system ine zvikamu zviviri: kutumira uye kugamuchira. Iyo yekufambisa chikamu inonyanya kuve nelaser, Optical modulator uye optical transmitting antenna. Iyo inogashira chikamu inonyanya kusanganisira optical kugamuchira antenna, optical sefa uyePhotodetector. Ruzivo rwunofanirwa kufambiswa rwunotumirwa kune aOptical modulatoryakabatana kune laser, iyo inogadzirisa ruzivo panelaseruye inoitumira kunze kuburikidza neantenna inotumira. Pakupera kwekugamuchira, antenna yekuona inogamuchira inogamuchira chiratidzo chelaser uye inotumira kune iyooptical detector, iyo inoshandura chiratidzo chelaser kuita chiratidzo chemagetsi uye ichichishandura kuita ruzivo rwekutanga mushure mekukwidziridzwa uye kuderedzwa.
Setiraiti yega yega muPentagon's yakarongwa mesh communications satellite network inogona kusvika mana laser links kuti vakwanise kutaurirana nemamwe masetellite, ndege, ngarava uye zviteshi zvepasi.Optical linkspakati pemasatellite akakosha pakubudirira kwemauto eUS low-Earth orbit constellation, iyo ichashandiswa pakutaurirana kwedata pakati pemapuraneti akawanda. Lasers inogona kupa yakakwirira yekufambisa data mitengo pane yechinyakare RF kutaurirana, asi zvakare inodhura zvakanyanya.
Mauto eUS nguva pfupi yadarika akapa mari inosvika bhiriyoni remadhora 1.8 muzvibvumirano zvechirongwa che126 Constellation kuti chivakwe chakaparadzana nemakambani eUS akagadzira imwe-to-mazhinji optical communication tekinoroji yekutumira-ku-multipoint inogona kubatsira kuderedza mutengo wekuvaka. nyeredzi nekudzikisa zvakanyanya kudiwa kwematerminal. Kubatana-kune-kwakawanda kunowanikwa nemudziyo unonzi manejaged optical communication array (MOCA for short), iyo yakasarudzika nekuti ine modular, uye iyo MOCA inotungamirwa optical communication array inogonesa optical inter-satellite links kutaura nayo. mamwe masatellite akawanda. Muchinyakare laser kutaurirana, zvese zvinongedzo-kune-inongedzo, hukama hweumwe-kune-umwe. NeMOCA, inter-satellite optical link inokwanisa kutaura nemasatelliti makumi mana akasiyana. Iyi tekinoroji haisi kungobatsira chete kudzikisa mutengo wekuvaka satellite constellations, kana mutengo wemanode wakaderedzwa, pane mukana wekushandisa akasiyana network architecture uye nekudaro mazinga akasiyana ebasa.
Imwe nguva yapfuura, satellite yeBeidou yekuChina yakaita kuyedza kutaurirana kwelaser, yakabudirira kufambisa chiratidzo muchimiro chelaser pasi yekugamuchira chiteshi, icho chakakosha kukosha kwekukurumidzira kutaurirana pakati pesetiraiti network mune ramangwana, kushandiswa kwelaser. Kukurukurirana kunogona kubvumira setiraiti kuendesa zviuru zvemamegabhiti edata pasekondi, hupenyu hwedu hwemazuva ese hwekurodha kumhanya ishoma megabits kusvika gumi megabits pasekondi, uye kana kutaurirana kwelaser kwaitika, Kurodha kumhanya kunogona kusvika akati wandei gigabytes sekondi, uye mune ramangwana. inogona kutogadzirwa kuita terabytes.
Parizvino, China's Beidou navigation system yakasaina zvibvumirano zvekushandira pamwe nenyika zana nemakumi matatu nenomwe pasi rose, ine imwe pesvedzero pasi rose, uye icharamba ichiwedzera mune ramangwana, kunyangwe China's Beidou navigation system iri seti yechitatu yemature mature satellite navigation system. asi ine nhamba huru yemasatelliti, inotopfuura nhamba yemasatelliti eiyo GPS system. Parizvino, iyo Beidou navigation system inoita basa rakakosha munhandare yemauto uye munharaunda yevagari. Kana kurukurirano yelaser ikagona kuitika, ichaunza mashoko akanaka kunyika.
