Izinzuzo zisobala, zifihliwe emfihlakalweni
Ngakolunye uhlangothi, ubuchwepheshe bokuxhumana nge-laser buvumelana kangcono nendawo ejulile yesikhala. Endaweni ejulile yesikhala, i-probe kufanele ibhekane nemisebe yendawo yonke, kodwa futhi ukuze inqobe udoti wasezulwini, uthuli nezinye izithiyo ohambweni olunzima ngebhande le-asteroid, amasongo amakhulu eplanethi, njalo njalo, izimpawu zomsakazo zisengozini enkulu yokuphazamiseka.
Ingqikithi ye-laser iwumsebe we-photon okhishwa ama-athomu ajabule, lapho ama-photon enezakhiwo ezibonakalayo ezihambisanayo kakhulu, ukuqondisa okuhle kanye nezinzuzo zamandla ezisobala. Ngezinzuzo zayo ezingokwemvelo,ama-laserbangazivumelanisa kangcono nendawo eyinkimbinkimbi yesikhala esijulile futhi bakhe izixhumanisi zokuxhumana ezizinzile nezithembekile.
Nokho, umaukuxhumana nge-laserifuna ukuvuna umphumela ofiselekayo, kumele yenze umsebenzi omuhle wokuqondanisa okunembile. Endabeni ye-Spirit satellite probe, uhlelo lokuqondisa, ukuzulazula kanye nokulawula lwe-flight computer master yayo ludlale indima ebalulekile, okubizwa ngokuthi “uhlelo lokukhomba, lokuthola kanye nokulandelela” ukuqinisekisa ukuthi i-terminal yokuxhumana nge-laser kanye nedivayisi yokuxhuma yethimba loMhlaba zihlala zigcina ukuqondanisa okunembile, ziqinisekisa ukuxhumana okuzinzile, kodwa futhi zinciphisa ngempumelelo izinga lamaphutha okuxhumana, zithuthukise ukunemba kokudluliswa kwedatha.
Ngaphezu kwalokho, lokhu kuqondana okunembile kungasiza amaphiko elanga ukuthi amunce ukukhanya kwelanga okuningi ngangokunokwenzeka, kunikeze amandla amaningiimishini yokuxhumana nge-laser.
Yiqiniso, akufanele kusetshenziswe amandla amaningi ngendlela ephumelelayo. Enye yezinzuzo zokuxhumana nge-laser ukuthi inamandla okusebenzisa kahle kakhulu, okungonga amandla amaningi kunokuxhumana ngomsakazo okuvamile, kunciphise umthwaloizitholi zesikhala esijulilengaphansi kwezimo zokuhlinzekwa kwamandla okulinganiselwe, bese wandisa ibanga lokundiza kanye nesikhathi sokusebenza se-izitholi, futhi uthole imiphumela eminingi yesayensi.
Ngaphezu kwalokho, uma kuqhathaniswa nokuxhumana komsakazo okuvamile, ukuxhumana nge-laser ngokwethiyori kunokusebenza okungcono ngesikhathi sangempela. Lokhu kubaluleke kakhulu ekuhloleni okujulile kwesikhala, kusiza ososayensi ukuthola idatha ngesikhathi futhi benze izifundo zokuhlaziya. Kodwa-ke, njengoba ibanga lokuxhumana landa, isimo sokubambezeleka sizobonakala kancane kancane, futhi inzuzo yesikhathi sangempela yokuxhumana nge-laser idinga ukuhlolwa.
Uma sibheka esikhathini esizayo, kungenzeka okwengeziwe
Njengamanje, umsebenzi wokuhlola isikhala ngokujulile kanye nokuxhumana ubhekene nezinselele eziningi, kodwa ngentuthuko eqhubekayo yesayensi nobuchwepheshe, kulindeleke ukuthi ikusasa lisebenzise izindlela ezahlukahlukene zokuxazulula inkinga.
Isibonelo, ukuze kunqotshwe ubunzima obubangelwa ibanga lokuxhumana elikude, i-deep space probe yesikhathi esizayo ingaba inhlanganisela yokuxhumana okuvamise kakhulu kanye nobuchwepheshe bokuxhumana nge-laser. Imishini yokuxhumana evamise kakhulu inganikeza amandla esignali aphezulu futhi ithuthukise ukuzinza kokuxhumana, kuyilapho ukuxhumana nge-laser kunesilinganiso sokudlulisa esiphezulu kanye nesilinganiso samaphutha esiphansi, futhi kufanele kulindeleke ukuthi abanamandla nabanamandla bangahlangana ukuze banikele ngebanga elide kanye nemiphumela yokuxhumana esebenza kahle.
Umfanekiso 1. Ukuhlolwa kokuxhumana nge-laser kwe-Early low Earth orbit
Ngokuqondene nemininingwane yobuchwepheshe bokuxhumana nge-laser, ukuze kuthuthukiswe ukusetshenziswa kwe-bandwidth futhi kuncishiswe ukubambezeleka, ama-deep space probe kulindeleke ukuthi asebenzise ubuchwepheshe bokubhala ikhodi nokucindezela obuthuthukisiwe kakhulu. Kalula nje, ngokwezinguquko endaweni yokuxhumana, imishini yokuxhumana nge-laser ye-deep space probe yesikhathi esizayo izolungisa ngokuzenzakalelayo imodi yokufaka ikhodi kanye ne-compression algorithm, futhi ilwele ukufeza umphumela omuhle kakhulu wokudlulisa idatha, ithuthukise izinga lokudlulisa futhi inciphise izinga lokulibaziseka.
Ukuze kunqotshwe imingcele yamandla emisebenzini yokuhlola isikhala esijulile futhi kuxazululwe izidingo zokushabalalisa ukushisa, i-probe izosebenzisa ubuchwepheshe obusebenzisa amandla aphansi kanye nobuchwepheshe bokuxhumana obuluhlaza ngokungenakugwenywa esikhathini esizayo, okungeke nje kunciphise ukusetshenziswa kwamandla kohlelo lokuxhumana, kodwa futhi kufeze ukuphathwa kokushisa okuphumelelayo kanye nokushabalalisa ukushisa. Akungabazeki ukuthi ngokusetshenziswa okusebenzayo kanye nokuthandwa kwalolu buchwepheshe, uhlelo lokuxhumana nge-laser lwama-deep space probe kulindeleke ukuthi lusebenze kahle, futhi ukukhuthazela kuzothuthukiswa kakhulu.
Ngokuthuthuka okuqhubekayo kobuhlakani bokwenziwa kanye nobuchwepheshe bokuzenzakalela, kulindeleke ukuthi ama-deep space probe aqedele imisebenzi ngokuzimela nangendlela ephumelelayo esikhathini esizayo. Isibonelo, ngemithetho esethiwe kanye nama-algorithms, i-detector ingakwazi ukucubungula idatha ngokuzenzakalela kanye nokulawula ukudlulisa okuhlakaniphile, igweme "ukuvimba" ulwazi futhi ithuthukise ukusebenza kahle kokuxhumana. Ngesikhathi esifanayo, ubuhlakani bokwenziwa kanye nobuchwepheshe bokwenzakalela kuzosiza abacwaningi ukunciphisa amaphutha okusebenza futhi bathuthukise ukunemba nokuthembeka kwemisebenzi yokuthola, kanye nezinhlelo zokuxhumana nge-laser nazo zizozuza.
Phela, ukuxhumana nge-laser akunamandla onke, futhi imisebenzi yokuhlola isikhala esijulile yesikhathi esizayo ingaqaphela kancane kancane ukuhlanganiswa kwezindlela zokuxhumana ezahlukahlukene. Ngokusebenzisa ngokuphelele ubuchwepheshe obuhlukahlukene bokuxhumana, njengokuxhumana ngomsakazo, ukuxhumana nge-laser, ukuxhumana kwe-infrared, njll., i-detector ingadlala umphumela omuhle kakhulu wokuxhumana kubhendi yezindlela eziningi, yama-frequency amaningi, futhi ithuthukise ukuthembeka nokuzinza kokuxhumana. Ngesikhathi esifanayo, ukuhlanganiswa kwezindlela zokuxhumana ezahlukahlukene kusiza ekufezeni umsebenzi wokubambisana wemisebenzi eminingi, kuthuthukiswe ukusebenza okuphelele kwama-detector, bese kukhuthaza izinhlobo eziningi nenani lama-detector ukuze enze imisebenzi eyinkimbinkimbi kakhulu esikhaleni esijulile.
