Imbali yetekhnoloji yoluntu inokubonwa njengokufuna ngokungapheliyo “ukuphucula”—izixhobo zangaphandle ezikhulisa amandla endalo.
Umzekelo, umlilo wawusebenza njengenkqubo yokugaya ukutya "eyongeziweyo", ukhulula amandla angakumbi ophuhliso lobuchopho. Unomathotholo, owazalwa ngasekupheleni kwenkulungwane ye-19, waba "yintambo yelizwi yangaphandle," evumela amazwi ukuba ahambe ngesantya sokukhanya kwihlabathi liphela.
Namhlanje,I-AR (iNqobo eyongeziweyo)ivela njenge "liso langaphandle" - idibanisa ihlabathi elibonakalayo nelokwenyani, iguqula indlela esibona ngayo indawo esingqongileyo.
Nangona isithembiso sangaphambili sithenjisiwe, inguqu ye-AR ayisekho emva kolindelo. Abanye abasunguli bezinto ezintsha bazimisele ukukhawulezisa olu tshintsho.
Ngomhla wama-24 kuSeptemba, iYunivesithi yaseWestlake, yabhengeza inkqubela phambili ebalulekileyo kubuchwepheshe bokubonisa i-AR.
Ngokutshintsha iglasi okanye iresin yendabuko ngei-silicon carbide (i-SiC), baphuhlise iilensi ze-AR ezibhityileyo kakhulu nezikhaphukhaphu—nganye inobunzima obufanayo2.7 iigramkwaye kuphelaUbukhulu obuyi-0.55 mm—zincinci kuneeglasi zelanga eziqhelekileyo. Iilensi ezintsha zikwavumelaisiboniso esipheleleyo semibala esibanzi (i-FOV)kwaye kususwe "izinto ezidumileyo zomnyama" ezichaphazela iiglasi ze-AR eziqhelekileyo.
Olu tshintsho lunokwenzatshintsha uyilo lwezihlangu zamehlo ze-ARkwaye kusondezwe i-AR ekusetyenzisweni kwabathengi abaninzi.
Amandla eSilicon Carbide
Kutheni ukhetha i-silicon carbide kwiilensi ze-AR? Ibali liqala ngo-1893, xa isazinzulu saseFransi uHenri Moissan safumanisa ikristale eqaqambileyo kwiisampulu ze-meteorite ezivela eArizona—ezenziwe ngekhabhoni kunye ne-silicon. Eyaziwa namhlanje njengeMoissanite, le nto ifana nelitye iyathandwa ngenxa yesalathiso sayo esiphezulu sokuqaqamba kunye nokukhanya xa kuthelekiswa needayimani.
Phakathi kwinkulungwane yama-20, iSiC yavela njenge-semiconductor yesizukulwana esilandelayo. Iipropati zayo eziphezulu zobushushu nezombane zenze ukuba ibe luncedo kakhulu kwizithuthi zombane, izixhobo zonxibelelwano, kunye neeseli zelanga.
Xa kuthelekiswa nezixhobo ze-silicon (ubuninzi be-300°C), izinto ze-SiC zisebenza ukuya kuthi ga kwi-600°C nge-frequency ephezulu ngokuphindwe kalishumi kunye nokusebenza kakuhle kwamandla. Ukuqhuba kwayo okuphezulu kobushushu kukwanceda ekupholiseni ngokukhawuleza.
Ngokwendalo inqabile—ifumaneka kakhulu kwi-meteorites—imveliso ye-SiC yokwenziwa inzima kwaye ibiza kakhulu. Ukukhulisa ikristale eyi-2 cm kuphela kufuna i-furnace engama-2300°C esebenza iintsuku ezisixhenxe. Emva kokukhula, ubunzima bedayimani yale nto benza kube nzima ukusika nokucubungula.
Enyanisweni, ingqwalasela yokuqala yelebhu kaNjingalwazi uQiu Min kwiYunivesithi yaseWestlake yayikukusombulula kanye le ngxaki—ukuphuhlisa iindlela ezisekelwe kwilaser zokusika iikristale zeSiC ngokufanelekileyo, ukuphucula kakhulu isivuno kunye nokunciphisa iindleko.
Ngethuba lale nkqubo, iqela likwaqaphele enye ipropati eyahlukileyo ye-pure SiC: i-refractive index ephawulekayo ye-2.65 kunye ne-optical clearance xa ingafakwanga—efanelekileyo kwi-AR optics.
Impumelelo: Itekhnoloji ye-Diffractive Waveguide
KwiYunivesithi yaseWestlakeIlebhu yeNanophotonics kunye neZixhobo zoKusebenzisa izixhobo, iqela leengcali ze-optics liqalise ukuphonononga indlela yokusebenzisa i-SiC kwiilensi ze-AR.
In i-AR esekelwe kwisikhokelo samaza esidibanisayo, iprojektha encinci ecaleni kweziglasi ikhupha ukukhanya ngendlela ecwangcisiweyo ngononophelo.Iigrating zesikali esincincikwilensi jika ukukhanya uze ukukhokele, ukukhanyise izihlandlo ezininzi ngaphambi kokuba ukukhokelele ngqo emehlweni onxibeyo.
Ngaphambili, ngenxaisalathisi esiphantsi sokurhawuzelela seglasi (malunga ne-1.5–2.0), kufuneka izikhokelo zamaza zemveliiileya ezininzi ezipakishwe ndawonye-iphumela kwiiilensi eziqinileyo, ezinzimakunye nezinto ezibonakalayo ezingafunekiyo ezifana "neepateni zomnyama" ezibangelwa kukukhanya okusingqongileyo. Iileya zangaphandle ezikhuselayo zongezwa ngakumbi kwi-lens bulk.
NgeIsalathisi sokuqaqamba okuphezulu kakhulu seSiC (2.65), aumaleko omnye wesikhokelo samazangoku kwanele ukufota ngemibala epheleleyo ngeI-FOV idlula i-80°—iphinda kabini amandla ezinto eziqhelekileyo. Oku kuphucula kakhuluukuntywiliselwa kunye nomgangatho womfanekisokwimidlalo, ukubonisa idatha, kunye nezicelo zobungcali.
Ngaphezu koko, uyilo oluchanekileyo lwegridi kunye nokulungiswa okucokisekileyo kunciphisa iziphumo zombala werainbow eziphazamisayo.ukuqhuba okufudumeleyo okungaqhelekanga, iilensi zinokunceda nasekususeni ubushushu obuveliswa zizinto ze-AR—ukusombulula omnye umceli mngeni kwiiglasi ze-AR ezincinci.
Ukucinga ngokutsha ngeMithetho yoYilo lwe-AR
Okunomdla kukuba, olu tshintsho luqale ngombuzo olula ovela kuNjingalwazi uQiu:"Ingaba umda we-2.0 refractive index uyasebenza ngokwenene?"
Kangangeminyaka, isithethe soshishino sasicinga ukuba ii-refractive indices ezingaphezulu kwe-2.0 ziya kubangela ukuphazamiseka kwe-optical. Ngokuphikisa le nkolelo nokusebenzisa i-SiC, iqela livule amathuba amatsha.
Ngoku, iiglasi zeSiC AR zomzekelo—ilula, izinzile ngokobushushu, kunye nemifanekiso ecacileyo yemibala epheleleyo—zikulungele ukuphazamisa imakethi.
Ngelixa elizayo
Kwihlabathi apho i-AR iza kuyila ngokutsha indlela esibona ngayo inyani, eli bali likaukuguqula "ilitye elinqabileyo elivela esibhakabhakeni" libe yiteknoloji ye-optical esebenza kakhulububungqina bobuchule bomntu.
Ukusuka endaweni yeedayimani ukuya kwizinto ezintsha ze-AR yesizukulwana esilandelayo,i-silicon carbidengokwenene ikhanyisa indlela eya phambili.
