Iingenelo zicacile, zifihliwe kwimfihlo
Kwelinye icala, iteknoloji yonxibelelwano nge-laser iyakwazi ukulungelelana nendalo esingqongileyo esinzulu. Kwindawo esingqongileyo esinzulu, i-probe kufuneka ijongane nemisebe yendalo yonke, kodwa ukuze yoyise inkunkuma yasezulwini, uthuli kunye neminye imiqobo kuhambo olunzima oludlula kwibhanti ye-asteroid, izangqa ezinkulu zeplanethi, njl.njl., imiqondiso yerediyo isengozini enkulu yokuphazamiseka.
Ingqwalasela yelaser ngumqadi wephoton okhutshwa ziiathom ezivuselelweyo, apho iiphoton zineempawu ezibonakalayo ezihambelanayo, isikhokelo esihle kunye neenzuzo zamandla ezicacileyo. Ngeenzuzo zayo ezisisiseko,iileyizabanokuziqhelanisa ngcono nendawo enzulu engqongileyo kwaye bakhe amakhonkco onxibelelwano azinzileyo nathembekileyo.
Nangona kunjalo, ukubaunxibelelwano lwelaserifuna ukuvuna isiphumo esifunekayo, kufuneka yenze umsebenzi olungileyo wokulungelelanisa ngokuchanekileyo. Kwimeko ye-Spirit satellite probe, inkqubo yolwalathiso, ukuhamba kunye nolawulo lwe-flight computer master yayo idlale indima ebalulekileyo, oko kubizwa ngokuba yi-"inkqubo yokukhomba, yokufumana kunye nokulandelela" ukuqinisekisa ukuba i-terminal yonxibelelwano lwe-laser kunye nesixhobo soqhagamshelo seqela loMhlaba zihlala zigcina ulungelelwaniso oluchanekileyo, ziqinisekisa unxibelelwano oluzinzileyo, kodwa zikwanciphisa ngempumelelo izinga leempazamo zonxibelelwano, ziphucule ukuchaneka kokudluliselwa kwedatha.
Ukongeza, olu lungelelwaniso luchanekileyo lunokunceda amaphiko elanga ukuba afunxe ukukhanya kwelanga okuninzi kangangoko kunokwenzeka, nto leyo enika amandla amaninziizixhobo zonxibelelwano nge-laser.
Kakade ke, akufuneki kusetyenziswe amandla amaninzi ngokufanelekileyo. Enye yeengenelo zonxibelelwano lwelaser kukuba lusebenzisa amandla kakuhle kakhulu, nto leyo enokonga amandla amaninzi kunonxibelelwano lwerediyo lwendabuko, inciphise umthwaloizixhobo zokubona indawo enzuluphantsi kweemeko zobonelelo lwamandla olulinganiselweyo, uze wandise umgama wokubhabha kunye nexesha lokusebenzaizixhobo zokufumanisa, kwaye ifumana iziphumo zesayensi ezingaphezulu.
Ukongeza, xa kuthelekiswa nonxibelelwano lwerediyo lwendabuko, unxibelelwano lwelaser ngokwethiyori lusebenza ngcono ngexesha langempela. Oku kubaluleke kakhulu ekuphononongeni nzulu isithuba, kunceda izazinzulu ukuba zifumane idatha ngexesha kwaye zenze izifundo zohlalutyo. Nangona kunjalo, njengoko umgama wonxibelelwano usanda, into yokulibaziseka iya kubonakala kancinci kancinci, kwaye inzuzo yonxibelelwano lwelaser ngexesha langempela kufuneka ivavanywe.
Ukujonga kwixesha elizayo, kuninzi okunokwenzeka
Okwangoku, umsebenzi wokuhlola isithuba esinzulu kunye nonxibelelwano ujongene nemingeni emininzi, kodwa ngophuhliso oluqhubekayo lwesayensi kunye netekhnoloji, kulindeleke ukuba ikamva lisebenzise iindlela ezahlukeneyo zokusombulula le ngxaki.
Umzekelo, ukuze koyiswe ubunzima obubangelwa kumgama wonxibelelwano olukude, i-deep space probe yexesha elizayo inokuba yindibaniselwano yonxibelelwano olusebenzisa i-frequency ephezulu kunye netekhnoloji yonxibelelwano nge-laser. Izixhobo zonxibelelwano olusebenzisa i-frequency ephezulu zinokubonelela ngamandla aphezulu esignali kwaye ziphucule uzinzo lonxibelelwano, ngelixa unxibelelwano nge-laser lunesantya esiphezulu sokudlulisela kunye nesantya esiphantsi seempazamo, kwaye kufanele kulindeleke ukuba ezomeleleyo nezinamandla zinokudibana ukuze zinegalelo kumgama omde kunye neziphumo zonxibelelwano ezisebenzayo ngakumbi.
Umfanekiso 1. Uvavanyo lonxibelelwano lwelaser olujikeleza umhlaba olusezantsi kwangoko
Ngokuphathelele iinkcukacha zobuchwepheshe bonxibelelwano lwelaser, ukuze kuphuculwe ukusetyenziswa kwe-bandwidth kunye nokunciphisa i-latency, ii-deep space probes kulindeleke ukuba zisebenzise ubuchwepheshe obukrelekrele ngakumbi bokubhala ikhowudi kunye noxinzelelo. Ngamafutshane, ngokweenguqu kwimeko-bume yonxibelelwano, izixhobo zonxibelelwano lwelaser ze-deep space probe yexesha elizayo ziya kulungisa ngokuzenzekelayo imo yekhowudi kunye ne-compression algorithm, kwaye zizame ukufezekisa isiphumo sokudlulisa idatha esingcono, ziphucule izinga lokudlulisa kwaye zinciphise inqanaba lokulibaziseka.
Ukuze koyiswe imida yamandla kwimisebenzi yokuhlola isithuba esinzulu kwaye kusonjululwe iimfuno zokusasazwa kobushushu, iprobe ngokuqinisekileyo iya kusebenzisa iteknoloji yamandla aphantsi kunye neteknoloji yonxibelelwano eluhlaza kwixesha elizayo, engazukunciphisa kuphela ukusetyenziswa kwamandla kwenkqubo yonxibelelwano, kodwa ikwafezekisa ulawulo lobushushu olufanelekileyo kunye nokusasazwa kobushushu. Akukho mathandabuzo ukuba ngokusetyenziswa okusebenzayo kunye nokwaziswa kwezi teknoloji, inkqubo yonxibelelwano lwelaser yeeprobe zesithuba esinzulu kulindeleke ukuba isebenze ngokuzinzileyo, kwaye ukunyamezela kuya kuphucuka kakhulu.
Ngokuqhubeka nokuqhubela phambili kobukrelekrele bokwenziwa kunye netekhnoloji yokuzenzekela, kulindeleke ukuba ii-deep space probes zigqibe imisebenzi ngokuzimeleyo nangokufanelekileyo kwixesha elizayo. Umzekelo, ngokusebenzisa imithetho esele imiselwe kunye nee-algorithms, i-detector inokwenza ukucutshungulwa kwedatha ngokuzenzekelayo kunye nolawulo lokudlulisa ulwazi olukrelekrele, iphephe "ukuvimba" ulwazi kwaye iphucule ukusebenza kakuhle konxibelelwano. Kwangaxeshanye, ubukrelekrele bokwenziwa kunye netekhnoloji yokuzenzekela kuya kunceda abaphandi ukunciphisa iimpazamo zokusebenza kunye nokuphucula ukuchaneka kunye nokuthembeka kwemisebenzi yokufumanisa, kwaye iinkqubo zonxibelelwano nge-laser nazo ziya kuzuza.
Kaloku, unxibelelwano lwelaser alunawo amandla onke, kwaye imisebenzi yokuhlola isithuba esinzulu kwixesha elizayo inokufezekisa ukuhlanganiswa kweendlela ezahlukeneyo zonxibelelwano. Ngokusebenzisa ngokupheleleyo ubuchwepheshe obahlukeneyo bonxibelelwano, obufana nonxibelelwano lwerediyo, unxibelelwano lwelaser, unxibelelwano lwe-infrared, njl.njl., isixhobo sokubona singadlala isiphumo esihle sonxibelelwano kwi-multi-path, multi-frequency band, kwaye siphucule ukuthembeka kunye nokuzinza konxibelelwano. Kwangaxeshanye, ukuhlanganiswa kweendlela ezahlukeneyo zonxibelelwano kunceda ekufezekiseni umsebenzi wokubambisana wemisebenzi emininzi, ukuphucula ukusebenza ngokupheleleyo kwezixhobo zokubona, kwaye emva koko kukhuthaze iintlobo ezininzi kunye namanani ezixhobo zokubona ukuba zenze imisebenzi enzima ngakumbi kwindawo enzulu.
