Umlando wobuchwepheshe babantu ungabonakala njengokuphishekela okungapheli “ukuthuthukiswa”—amathuluzi angaphandle akhulisa amakhono emvelo.
Isibonelo, umlilo, wasebenza njengesimiso sokugaya ukudla “esingezelayo”, ukhulula amandla engeziwe okukhula kobuchopho. Umsakazo, owazalwa ngasekupheleni kwekhulu le-19, waba “intambo yezwi yangaphandle,” okuvumela amazwi ukuba ahambe ngesivinini sokukhanya emhlabeni wonke.
Namuhla,I-AR (Iqiniso Elingathandwa)kuvela “njengeso langaphandle”—elihlanganisa imihlaba ebonakalayo neyangempela, liguqula indlela esibona ngayo indawo esizungezile.
Kodwa naphezu kwesithembiso sasekuqaleni, ukuvela kwe-AR kushiywe ngemuva kokulindela. Abanye abasunguli bazimisele ukusheshisa lolu shintsho.
NgoSepthemba 24, iWestlake University, yamemezela intuthuko ebalulekile kubuchwepheshe bokubonisa i-AR.
Ngokushintsha ingilazi noma i-resin yendabuko ngei-silicon carbide (i-SiC), bakha amalensi e-AR amancane kakhulu futhi alula kakhulu—ngalinye linesisindo njeAmagremu angu-2.7futhi kuphelaUbukhulu obungu-0.55 mm—zincane kunezibuko zelanga ezivamile. Amalensi amasha nawo avumelaisibonisi esinombala ogcwele wensimu ebanzi yokubuka (i-FOV)futhi kuqedwe “izinto zobuciko zothingo” ezidumile ezihlasela izibuko ze-AR ezivamile.
Lokhu kusungula izinto ezintsha kungenzashintsha umklamo wezibuko ze-ARfuthi kusondeze i-AR ekwamukelweni kwabathengi abaningi.
Amandla e-Silicon Carbide
Kungani ukhethe i-silicon carbide yamalensi e-AR? Indaba iqala ngo-1893, lapho usosayensi waseFrance uHenri Moissan ethola ikristalu elikhazimulayo kumasampula e-meteorite avela e-Arizona—enziwe nge-carbon ne-silicon. Namuhla eyaziwa ngokuthi i-Moissanite, le nto efana netshe ithandwa ngenxa yenkomba yayo ephezulu yokukhanya nokukhanya uma kuqhathaniswa namadayimane.
Maphakathi nekhulu lama-20, i-SiC nayo yavela njenge-semiconductor yesizukulwane esilandelayo. Izakhiwo zayo ezinhle kakhulu zokushisa kanye nogesi ziyenze yaba usizo kakhulu ezimotweni zikagesi, emishinini yokuxhumana, kanye nakumaseli elanga.
Uma kuqhathaniswa namadivayisi e-silicon (ubuningi buka-300°C), izingxenye ze-SiC zisebenza kufika ku-600°C ngemvamisa ephezulu izikhathi eziyi-10 kanye nokusebenza kahle kwamandla okukhulu kakhulu. Ukushisa kwayo okuphezulu nakho kusiza ekupholiseni ngokushesha.
Njengoba kungavamile ngokwemvelo—okutholakala kakhulu kuma-meteorite—ukukhiqizwa kwe-SiC yokwenziwa kunzima futhi kuyabiza. Ukukhulisa ikristalu engu-2 cm kuphela kudinga isithando somlilo esingu-2300°C esisebenza izinsuku eziyisikhombisa. Ngemva kokukhula, ubulukhuni bento efana nedayimane benza ukusika nokucubungula kube yinselele.
Eqinisweni, ukugxila kokuqala kwelebhu kaSolwazi Qiu Min eWestlake University kwakuwukuxazulula le nkinga ngqo—ukuthuthukisa amasu asekelwe ku-laser ukuze anqume amakristalu e-SiC ngempumelelo, okuthuthukisa kakhulu isivuno futhi kwehlise izindleko.
Phakathi nale nqubo, ithimba liphinde laphawula enye imfanelo eyingqayizivele ye-SiC emsulwa: inkomba yokubuka ehlaba umxhwele engu-2.65 kanye nokucaca kwe-optical uma ingavulwanga—okufanelekela i-AR optics.
Ukuphumelela: Ubuchwepheshe be-Diffractive Waveguide
E-Westlake University'sIlebhu ye-Nanophotonics kanye ne-Instrumentation, ithimba lochwepheshe be-optics laqala ukuhlola indlela yokusebenzisa i-SiC kumalensi e-AR.
In i-AR esekelwe kumhlahlandlela wamagagasi ohlukanisayo, iphrojektha encane ohlangothini lwezibuko ikhipha ukukhanya ngendlela eklanywe ngokucophelela.Ama-grating esikali esincanekulensi khipha ukukhanya bese ukuqondisa ukukhanya, ukukhanyise izikhathi eziningi ngaphambi kokukuqondisa ngqo emehlweni ogqokile.
Ngaphambilini, ngenxainkomba ephansi yokubuka kwengilazi (cishe u-1.5–2.0), kudingeka ama-waveguide endabukoizendlalelo eziningi ezihlanganisiwe-Imiphumelaamalensi amakhulu, asindayokanye nezinto ezibonakalayo ezingathandeki ezifana “namaphethini othingo” abangelwa ukuphambuka kokukhanya kwemvelo. Izendlalelo zangaphandle ezivikelayo zengezwe kakhulu ku-lens bulk.
NgeInkomba yokubuka ephezulu kakhulu ye-SiC (2.65), aisendlalelo esisodwa se-waveguidemanje sekwanele ukuthwebula izithombe ezinemibala egcwele nge-I-FOV idlula ama-80°—kuphindeka kabili amakhono ezinto ezivamile. Lokhu kuthuthukisa kakhuluukucwiliswa kanye nekhwalithi yesithombekwezemidlalo, ukubonisa idatha, kanye nezinhlelo zokusebenza zobungcweti.
Ngaphezu kwalokho, imiklamo ye-grating enembile kanye nokucubungula okuhle kakhulu kunciphisa imiphumela yombala we-rainbow ephazamisayo. Kuhlanganiswe ne-SiC'sukuhanjiswa kokushisa okungavamile, amalensi angasiza ngisho nokususa ukushisa okubangelwa yizingxenye ze-AR—ukuxazulula enye inselele ezingilazini ze-AR ezincane.
Ukucabanga Kabusha Ngemithetho Yokuklama I-AR
Ngokuthakazelisayo, lokhu kuphumelela kwaqala ngombuzo olula ovela kuSolwazi Qiu:"Ingabe umkhawulo wenkomba ye-refractive engu-2.0 uyasebenza ngempela?"
Sekuyiminyaka eminingi, imboni yayicabanga ukuthi izinkomba zokukhanya ezingaphezu kuka-2.0 zingabangela ukuphambuka kokukhanya. Ngokuphikisa le nkolelo nokusebenzisa i-SiC, ithimba livule amathuba amasha.
Manje, izibuko ze-SiC AR—elula, ezinzile ngokwezinga lokushisa, enezithombe ezicacile zemibala egcwele—bakulungele ukuphazamisa imakethe.
Ikusasa
Ezweni lapho i-AR izokwakha kabusha indlela esibheka ngayo iqiniso, le ndabaukuguqula "itshe eliyigugu elivela esikhaleni" elingavamile libe ubuchwepheshe bokukhanya obusebenza kahle kakhulukuwubufakazi bokuhlakanipha komuntu.
Kusukela esikhundleni samadayimane kuya ezintweni eziphumelelayo ze-AR yesizukulwane esilandelayo,i-silicon carbidengempela ikhanyisa indlela eya phambili.
Mayelana NATHI
SingaXKH, umkhiqizi ohamba phambili ogxile kuma-wafer e-Silicon Carbide (SiC) namakristalu e-SiC.
Ngamakhono okukhiqiza athuthukile kanye neminyaka yobuchwepheshe, sihlinzekaizinto ze-SiC ezihlanzekile kakhulukwezobuchwepheshe be-semiconductors besizukulwane esilandelayo, ama-optoelectronics, kanye nobuchwepheshe be-AR/VR obusafufusa.
Ngaphezu kwezicelo zezimboni, i-XKH iphinda ikhiqizeamatshe ayigugu e-Moissanite aphezulu (i-synthetic SiC), esetshenziswa kabanzi ezintweni zokuhloba ezinhle ngenxa yobuhle bazo obumangalisayo nokuqina kwazo.
Kungakhathaliseki ukuthiama-elekthronikhi anamandla, i-optics ethuthukisiwe, noma ubucwebe obusezingeni eliphezulu, i-XKH iletha imikhiqizo ye-SiC ethembekile nesezingeni eliphezulu ukuze ihlangabezane nezidingo ezishintshayo zezimakethe zomhlaba wonke.
