Silicon Carbide Imayatsa Magalasi a AR, Kutsegula Zokumana Nazo Zatsopano Zopanda Malire

Mbiri ya ukadaulo wa anthu nthawi zambiri imawonedwa ngati kufunafuna kosalekeza "zowonjezera" - zida zakunja zomwe zimakulitsa luso lachilengedwe.

Mwachitsanzo, moto unagwira ntchito ngati njira yowonjezera kugaya chakudya, kumasula mphamvu zambiri kuti ubongo ukule. Radio, yomwe inayamba kumapeto kwa zaka za m'ma 1800, inakhala "cholumikizira mawu chakunja," chomwe chimalola mawu kuyenda pa liwiro la kuwala padziko lonse lapansi.

Lero,AR (Zoona Zowonjezereka)ikubwera ngati "diso lakunja" - kulumikiza maiko enieni ndi enieni, kusintha momwe timaonera malo otizungulira.

Ngakhale kuti zinthu zinayamba kuoneka ngati zachitika kale, kusintha kwa AR sikunachitike bwino. Akatswiri ena opanga zinthu zatsopano atsimikiza mtima kupititsa patsogolo kusinthaku.

Pa Seputembala 24, Westlake University, idalengeza kupita patsogolo kwakukulu muukadaulo wowonetsera AR.

Mwa kusintha galasi lachikhalidwe kapena utomoni ndisilicon carbide (SiC), adapanga magalasi a AR opyapyala kwambiri komanso opepuka—onse olemera okhaMagalamu 2.7ndipo kokha0.55 mm makulidwe—woonda kuposa magalasi a dzuwa wamba. Magalasi atsopanowa amathandizansochiwonetsero chamitundu yonse (FOV) cha malo owonera bwinondi kuchotsa "zinthu zakale zodziwika bwino za utawaleza" zomwe zimawononga magalasi achikhalidwe a AR.

Luso limeneli likhozaSinthani mawonekedwe a maso a ARndipo bweretsani AR pafupi ndi kugwiritsa ntchito anthu ambiri.

Mphamvu ya Silicon Carbide

N’chifukwa chiyani mungasankhe silicon carbide pa magalasi a AR? Nkhaniyi imayamba mu 1893, pamene wasayansi wa ku France Henri Moissan anapeza galasi lowala kwambiri m’zitsanzo za miyala ya m’mlengalenga kuchokera ku Arizona—lopangidwa ndi kaboni ndi silicon. Masiku ano, chinthu chonga miyala yamtengo wapatalichi chimadziwika kuti Moissanite, ndipo chimakondedwa chifukwa cha kuchuluka kwa kuwala kwake poyerekeza ndi diamondi.

Pakati pa zaka za m'ma 1900, SiC inayambanso kukhala semiconductor ya m'badwo wotsatira. Mphamvu zake zabwino kwambiri zotenthetsera ndi zamagetsi zapangitsa kuti ikhale yofunika kwambiri m'magalimoto amagetsi, zida zolumikizirana, ndi ma solar cell.

Poyerekeza ndi zipangizo za silicon (300°C max), zigawo za SiC zimagwira ntchito pa kutentha mpaka 600°C ndi ma frequency okwera ka 10 komanso mphamvu zambiri. Kutentha kwake kwakukulu kumathandizanso kuziziritsa mofulumira.

Mwachilengedwe, zomwe zimapezeka kawirikawiri m'miyala ya miyala, kupanga SiC yopangidwa ndi zinthu zopanga n'kovuta komanso kokwera mtengo. Kupanga kristalo ya 2 cm yokha kumafuna ng'anjo ya 2300°C yomwe imagwira ntchito kwa masiku asanu ndi awiri. Pambuyo pokula, kuuma kwa chinthucho ngati diamondi kumapangitsa kudula ndi kukonza kukhala kovuta.

Ndipotu, cholinga choyambirira cha labu ya Pulofesa Qiu Min ku Westlake University chinali kuthetsa vutoli—kupanga njira zogwiritsa ntchito laser kuti zidule bwino makhiristo a SiC, zomwe zimapangitsa kuti phindu likhale lochepa kwambiri komanso kuchepetsa ndalama.

Pa nthawi imeneyi, gululi linaonanso khalidwe lina lapadera la SiC yoyera: chizindikiro chochititsa chidwi cha refractive cha 2.65 ndi kuwala kowonekera bwino pamene sikunatsegulidwe—koyenera kwa AR optics.

Kupambana: Ukadaulo Wosiyanasiyana wa Mafunde

Ku Westlake UniversityLabu Yopangira Nanophotonics ndi Zida, gulu la akatswiri a maso linayamba kufufuza momwe angagwiritsire ntchito SiC mu magalasi a AR.

In AR yochokera ku diffractive waveguide, pulojekitala kakang'ono kumbali ya magalasi kamatulutsa kuwala kudzera munjira yokonzedwa bwino.Ma grating a nano-scalePa lenzi, tulutsani kuwala ndi kutsogolera kuwalako, mukuuwunikira kangapo musanakulowetse m'maso mwa wovalayo.

Kale, chifukwa chagalasi looneka ngati galasi losawoneka bwino (pafupifupi 1.5–2.0), malangizo achikhalidwe a mafunde ofunikirazigawo zingapo zodzaza-kutsatira mumagalasi okhuthala, olemerandi zinthu zosafunikira monga "mawonekedwe a utawaleza" omwe amayamba chifukwa cha kuwala kwachilengedwe. Zigawo zakunja zoteteza zinawonjezeredwa ku lens lalikulu.

NdiChizindikiro cha refractive cha SiC chapamwamba kwambiri (2.65), agawo limodzi la mafundetsopano ndi zokwanira kujambula zithunzi zamitundu yonse ndiFOV yoposa 80°—kuwirikiza kawiri mphamvu za zipangizo zachizolowezi. Izi zimawonjezera kwambirikumiza ndi khalidwe la chithunzipamasewera, kuwonetsa deta, ndi mapulogalamu aukadaulo.

Kuphatikiza apo, mapangidwe olondola a grating ndi kukonza bwino kwambiri kumachepetsa zotsatira zosokoneza za utawaleza.kutentha kwapadera, magalasiwa angathandizenso kuchotsa kutentha komwe kumapangidwa ndi zinthu za AR—kuthetsa vuto lina m'magalasi ang'onoang'ono a AR.

Kuganiziranso Malamulo a Kapangidwe ka AR

Chochititsa chidwi n'chakuti, kupita patsogolo kumeneku kunayamba ndi funso losavuta lochokera kwa Pulofesa Qiu:"Kodi malire a index ya 2.0 refractive index ndi othandizadi?"

Kwa zaka zambiri, malamulo a makampani ankaganiza kuti zizindikiro zowunikira pamwamba pa 2.0 zingayambitse kusokonekera kwa kuwala. Mwa kutsutsa chikhulupiriro ichi ndikugwiritsa ntchito SiC, gululo linatsegula mwayi watsopano.

Tsopano, magalasi a SiC AR oyambilira—wopepuka, wokhazikika pa kutentha, wokhala ndi zithunzi zowala bwino zamitundu yonse—akonzeka kusokoneza msika.

Tsogolo

M'dziko lomwe AR idzasintha momwe timaonera zenizeni, nkhani iyi yakusintha "mwala wamtengo wapatali wobadwira mumlengalenga" kukhala ukadaulo wapamwamba kwambiri wamagetsindi umboni wa nzeru za anthu.

Kuchokera m'malo mwa diamondi kupita ku zinthu zatsopano za AR ya m'badwo wotsatira,kabide ya silikoniikuwonetsadi njira yopitira patsogolo.

Zambiri zaife

Ife ndifeXKH, kampani yopanga zinthu zodziwika bwino kwambiri pogwiritsa ntchito ma wafer a Silicon Carbide (SiC) ndi ma crystal a SiC.
Ndi luso lapamwamba lopanga komanso zaka zambiri zaukadaulo, timaperekazipangizo za SiC zoyera kwambirikwa ma semiconductors a m'badwo wotsatira, ma optoelectronics, ndi ukadaulo watsopano wa AR/VR.

Kuwonjezera pa ntchito zamafakitale, XKH imapangansomiyala yamtengo wapatali ya Moissanite (SiC yopangidwa), zomwe zimagwiritsidwa ntchito kwambiri popanga zodzikongoletsera zabwino chifukwa cha kunyezimira kwawo kwapadera komanso kulimba kwawo.

Kaya zazamagetsi zamagetsi, kuwala kwapamwamba, kapena zodzikongoletsera zapamwamba, XKH imapereka zinthu zodalirika komanso zapamwamba za SiC kuti zikwaniritse zosowa zamisika yapadziko lonse lapansi.
