Ukuphuhliswa kwenkqubo ye-optical imaging yentsebenzo ephezulu ihlanganisa amanyathelo oyilo lwe-optical, ukuveliswa, ukuhlolwa, ukudibanisa kunye nokulungelelaniswa.Uyilo lwenkqubo ye-optical sisiqalo sayo yonke inkqubo yekhonkco lokuqonda inkqubo ye-optical system.Uhlalutyo lokunyamezelana yibhulorho ephambili phakathi koyilo kunye nokuveliswa.Ukusasazwa okunengqiqo kunye nokuchanekileyo kweempazamo zokwenziwa kwayo yonke imiphezulu ye-optical inceda ekufezekiseni ukuveliswa kwezinto eziphezulu ezichanekileyo.Ukuvavanywa komgangatho wezinto ezibonakalayo kuya kwenza uvavanyo oluchanekileyo lweziphumo zokuvelisa, okuya kunceda ukuqhubela phambili ukuphucula umgangatho wokwenziwa kwezinto ezibonakalayo.
Umzobo 1. Impazamo yefomu yommandla wendawo kunye novavanyo
Eyona ndlela isebenzayo yohlalutyo lonyamezelo oluye lwaqwalaselwa kwisithuba esingaphezu kwesiqingatha senkulungwane lusekelwe kumanani okunokwenzeka eMonte Carlo.Oku kunyamezelwa yinkcazo edibeneyo yokwakheka komhlaba wonke.Ixela elona xabiso liphezulu le-RMS okanye ixabiso le-PV lempazamo yokumila komphezulu.Ngexesha elifanayo, umgangatho wezinto ezibonakalayo ubonakaliswe kwakhona ngexabiso le-RMS okanye ixabiso le-PV yephutha lomhlaba.Nangona kunjalo, imeko yokwenyani yenkqubo yamehlo inzima kakhulu.Iindlela ezikhoyo zokuhlalutya ukunyamezela okusekelwe kwi-Monte Carlo azikwazi ukunika iimfuno ezahlukeneyo zokunyamezela kwiindawo ezahlukeneyo zomhlaba.Ixabiso le-RMS okanye ixabiso le-PV lempazamo yokumila komphezulu alikwazi ukuvavanya ngokuchanekileyo umgangatho wezinto ezibonakalayo.
Emva kweminyaka esixhenxe yemizamo, uZhu Jun, unjingalwazi onxulumene neSebe leZixhobo ezichanekileyo zeYunivesithi yaseTsinghua, waqinisekisa ukuba iindawo ezahlukeneyo zezinto ezibonakalayo zineemfuno ezahlukeneyo zokunyamezela, kwaye ucebise imodeli yokunyamezela kwendawo yendawo ye-optical surfaces.Imodeli yokunyamezela kwendawo inokufumana ngokuchanekileyo iimfuno ezahlukeneyo zokunyamezela kwiindawo ezahlukeneyo kwindawo, ukwenzela ukuba iindawo ezahlukeneyo zomphezulu zenziwe ngokweemfuno ezahlukeneyo zokuchaneka.Imodeli yonyamezelo yasekhaya ibhukuqa ithiyori yohlalutyo lonyamezelo lwehlabathi olusekwe kumathuba eenkcukacha-manani eMonte Carlo ngaphezulu kweminyaka engama-50.Iqela lophando libala ukunyamezela kwendawo yendawo yezibuko ezintathu ze-off-axis ezintathu ze-mirror optical system (Umfanekiso 1) kunye nezibuko ezimbini zenkqubo yohlobo lwe-Cassegrain (Umfanekiso 2), kunye nokulinganisa kunye nokuqinisekisa ukunyamezela.Isiphumo sokubala ukunyamezela sibonisa indawo ecacileyo.
Umzobo 2. Kwinkqubo yesipili esiphuma kwi-axis triple triple, unikezelo lokunyamezela umphezulu wasekhaya lwezipili ezithathu (a), (b) kunye (c) lusasazo olutenxa kumphezulu wezipili ezithathu ngokulandelelanayo.
Umzobo 3. Kwinkqubo ye-RC, hlalutya ukuhanjiswa kweprofayili yokunyamezela kwendawo yesibuko esiphambili kunye nesibuko sesibini ngaxeshanye (a), (b), (c) kukuhanjiswa kweprofayili yesipili sokuqala, kunye (d), (e) ), kunye (f) lunikezelo lweprofayili yokutenxa kwisipili sesibini, ngokulandelelanayo
Ngelo xesha, iqela lophando liphakamise umsebenzi wokuvavanya ngokuchanekileyo i-RWE yomgangatho wezinto ezibonakalayo ezihambelana ngokuthe ngqo nokusebenza kwe-imaging, ukubuyisela ixabiso le-RMS okanye i-PV yendabuko ukuvavanya umgangatho wezinto ezibonakalayo, kunye nokuvavanya umgangatho we uchungechunge lwezinto ezineempazamo ezahlukeneyo zomhlaba (Umfanekiso 3).Iziphumo zibonisa ukuba umgangatho wamacandelo anexabiso elifanayo le-PV okanye i-RMS lihlukile, kwaye amacandelo anokuchaneka kwejometri ephantsi anokuvelisa umgangatho womfanekiso ongcono kunezo zichanekileyo zejometri.
Izinto ezifanayo ezibonakalayo ze-RMS zinokwahlula umgangatho wazo wokucinga nge-RWE.Kwiqela lokuhlola imveliso, umgangatho wamacandelo emva kokuvelisa unokuvavanywa ngokuzimeleyo ngaphandle kwamaxwebhu oyilo.I-RWE inceda ukukhetha ngokukhawuleza amacandelo ahlangabezana neemfuno zomfanekiso, kwaye inika eyona ndibaniselwano ihambelanayo phakathi kwamacandelo ahlukeneyo.Umzobo 4. Umgangatho wamacandelo anexabiso elifanayo le-PV okanye i-RMS lihlukile
Isakhelo sonyamezelo sendawo esicetywayo kolu phononongo siya kubonelela ngenkxaso yobugcisa obutsha bokwenziwa kweenkqubo zamehlo, ngakumbi ukuchaneka okuphezulu kunye neenkqubo ezinkulu zokuvula indawo ezifana neenkqubo zelithography kunye neeteleskopu zendawo, kwaye ziya kuba nefuthe loguquko kwithiyori, iteknoloji kunye nemigangatho. kwintsimi yoyilo lwe-optical kunye nokuvelisa.NgoSeptemba 8, oku kuphunyezwa ngasentla kwapapashwa kwiphephancwadi i-OPTICA phantsi kwesihloko esithi "Impazamo yendawo yendawo kunye nokuvavanywa komgangatho weendawo ezibonakalayo".
