Imikhiqizo

Inyuvesi yaseTsinghua: indlela entsha yephutha lefomu lendawo yendawo kanye nokuhlolwa kwekhwalithi yezinto ezibonakalayo

Ukuthuthukiswa kwesistimu ye-imaging ye-optical esebenza kakhulu ihlanganisa izinyathelo zokuklama optical, ukukhiqiza, ukuhlola, ukuhlanganisa kanye nokulungiswa.Ukwakhiwa kwesistimu ye-optical kuyisiqalo salo lonke uchungechunge lwenqubo yokuqaphela uhlelo lwe-optical.Ukuhlaziywa kokubekezelelana kuyibhuloho eliyinhloko phakathi kokuklama nokukhiqiza.Ukusatshalaliswa okunengqondo nokunembile kwamaphutha okukhiqiza azo zonke izindawo ezikhanyayo kusiza ekufezekeni kokukhiqizwa kwento yokubona enembayo ephezulu.Ukuhlolwa kwekhwalithi yezinto ezibonakalayo kuzokwenza ukuhlolwa okunembile kwemiphumela yokukhiqiza, okuzosiza ukuthuthukisa ngokuqhubekayo ikhwalithi yokukhiqiza i-optical element.

Umfanekiso 1. Iphutha lefomu lendawo yendawo kanye nokuhlola

Indlela ephumelela kakhulu yokuhlaziya ukubekezelelana esiye yacatshangelwa isikhathi esingaphezu kwengxenye yekhulunyaka isekelwe ezibalweni zamathuba e-Monte Carlo.Lokhu kubekezelelana kuyincazelo ehlanganisiwe yawo wonke umumo ongaphezulu.Icacisa inani eliphakeme le-RMS noma inani le-PV lephutha lomumo ongaphezulu.Ngesikhathi esifanayo, ikhwalithi yezinto ezibonakalayo ibonakala ngenani le-RMS noma inani le-PV lephutha elingaphezulu.Kodwa-ke, isimo sangempela sesistimu ye-optical siyinkimbinkimbi kakhulu.Izindlela ezikhona zokuhlaziya ukubekezelelana okusekelwe ku-Monte Carlo azikwazi ukunikeza izidingo ezihlukene zokubekezelelana ezindaweni ezahlukene zomhlaba.Inani le-RMS noma inani le-PV lephutha lomumo ongaphezulu alikwazi ukuhlola ngokunembile ikhwalithi yezinto ezibonakalayo.

Ngemva kweminyaka eyisikhombisa yemizamo, u-Zhu Jun, uprofesa osebenzisana naye woMnyango Wezinsimbi Zokunemba Kwezinsimbi zaseNyuvesi yaseTsinghua, ukuqinisekisile ukuthi izindawo ezihlukene zezinto ezibonakalayo zinezidingo ezihlukile zokubekezelelana, futhi wahlongoza imodeli yendawo yokubekezelela ubuso bendawo yokubona.Imodeli yokubekezelelana kwendawo ingathola ngokunembile izidingo zokubekezelelana ezihlukene ezindaweni ezihlukene phezulu, ukuze izindawo ezihlukene zendawo zingenziwa ngokuvumelana nezidingo ezihlukene zokunemba.Imodeli yendawo yokubekezelelana ichitha ithiyori yokuhlaziya yokubekezelelana emhlabeni wonke ngokusekelwe emathubeni ezibalo e-Monte Carlo iminyaka engaphezu kwengu-50.Ithimba locwaningo libale ukubekezelelana kwendawo yezibuko ezintathu zesistimu yokubona isibuko esingaphandle kwe-axis emithathu (Umfanekiso 1) nezibuko ezimbili zohlobo lwesistimu ye-Cassegrain (Umfanekiso 2), futhi yalingisa futhi yaqinisekisa ukubekezelelana.Umphumela wokubala kokubekezelelana ubonisa ukwenziwa kwasendaweni okusobala.

Umfanekiso 2. Kusistimu yesibuko se-off-axis triple mirror, ukusabalaliswa kwendawo yokubekezelela indawo yezibuko ezintathu (a), (b) kanye (c) kuwukusabalalisa okuchezuka ebusweni bezibuko ezintathu ngokulandelanayo.

 ukukhiqizwa kwezinto 3

Umfanekiso 3. Kuhlelo lwe-RC, hlaziya ukusatshalaliswa kokubekezelelana kwephrofayela yendawo yesibuko esiyinhloko nesibuko sesibili ngesikhathi esisodwa (a), (b), (c) ukusabalalisa kokuchezuka kwephrofayela yesibuko esiyinhloko, kanye (d), (e) ), kanye (f) ukusatshalaliswa kokuchezuka kwephrofayili yesibuko sesibili, ngokulandelana

Ngesikhathi esifanayo, ithimba locwaningo liphakamise umsebenzi wokuhlola onembile we-RWE wekhwalithi yezinto ezibonakalayo ezihlotshaniswa ngokuqondile nokusebenza kwesithombe, esikhundleni se-RMS evamile noma amanani e-PV ukuze kuhlolwe ikhwalithi yezinto ezibonakalayo, futhi kuhlolwe ikhwalithi uchungechunge lwezakhi ezinamaphutha ahlukene angaphezulu (Umfanekiso 3).Imiphumela ibonisa ukuthi ikhwalithi yezingxenye ezinenani elifanayo le-PV noma i-RMS ihlukile, futhi izingxenye ezinokunemba okuphansi kwejometri zingase zikhiqize ikhwalithi ye-imaging engcono kunalezo ezinokunemba okuphezulu kwejometri.

ukukhiqizwa kwezinto4

Izinto ezifanayo ezibonakalayo ze-RMS zingaphinda zihlukanise ikhwalithi yazo yokucabanga nge-RWE.Ephathini yokuhlola ukukhiqiza, ikhwalithi yezingxenye ngemva kokukhiqiza ingahlolwa ngokuzimela ngaphandle kwemibhalo yokuklama.I-RWE isiza ukukhetha ngokushesha izingxenye ezihlangabezana nezidingo zesithombe, futhi inikeza inhlanganisela engcono kakhulu yokuqhathanisa phakathi kwezingxenye ezahlukene.Umfanekiso 4. Izinga lezingxenye ezinenani elifanayo le-PV noma i-RMS lihlukile

Uhlaka lwendawo lokubekezelelana oluhlongozwayo kulolu cwaningo luzohlinzeka ngosekelo olusha lwezobuchwepheshe ekukhiqizeni amasistimu okukhanya, ikakhulukazi amasistimu okukhanya okunemba okuphezulu kanye nama-aperture amakhulu afana nezinhlelo ze-lithography kanye nezibonakude zasemkhathini, futhi kuzoba nomthelela wokuguquguquka kumbono, ubuchwepheshe kanye namazinga. emkhakheni wokuklama nokukhiqiza optical.Ngomhla ziyisi-8 kuSepthemba, izimpumelelo ezingenhla zashicilelwa kujenali i-OPTICA ngaphansi kwesihloko esithi “Iphutha lendawo yendawo kanye nokuhlolwa kwekhwalithi yezindawo ezikhanyayo”.
