Gukwirakwiza ubushyuhe ni ikibazo cy'ingenzi ku birahure bya AR, cyane cyane mu gihe cyo kwerekana urumuri rwinshi no gukoreshwa igihe kirekire. Indorerwamo za silikoni za silikoni zishobora kwimura ubushyuhe buva mu bice by'urumuri, bikongera ubuziranenge n'ubuzima bw'igikoresho. Dushobora gutanga wafer ya SiC ifasha gucunga neza ubushyuhe muri ubwo buryo.
Ubukomere Bukomeye no Kudashira: Karubide ya silicon ni kimwe mu bikoresho bigoye cyane bizwi, kiza ku mwanya wa kabiri nyuma ya diyama. Ibi bituma lenzi za karubide ya silicon zidashira, zikwiriye gukoreshwa buri munsi. Mu buryo bunyuranye, ibikoresho by'ikirahure na resin bikunze gushwaragurika, ibyo bigira ingaruka ku buzima bw'umukoresha.
Ingaruka zo kurwanya umukororombya: Ibikoresho gakondo by'ikirahure mu birahuri bya AR bikunze gutanga ingaruka z'umukororombya, aho urumuri rwo mu kirere rugaragara ku buso bw'umuraba, bigatanga imiterere y'urumuri rw'amabara ahindagurika. Karubide ya silicon ishobora gukemura iki kibazo neza binyuze mu kunoza imiterere y'urumuri, bityo ikanoza ubwiza bw'urumuri kandi ikavanaho ingaruka z'umukororombya ziterwa no kugaragara k'urumuri rwo mu kirere ku buso bw'umuraba.
Iterambere ry'ikoranabuhanga rya Silicon Carbide mu birahuri bya AR
Mu myaka ya vuba aha, iterambere ry'ikoranabuhanga rya silicon carbide mu ndorerwamo za AR ryibanze cyane cyane ku iterambere rya lenses za diffraction waveguide. Diffraction waveguide ni ikoranabuhanga ryo kwerekana rihuza imiterere ya diffraction y'urumuri n'imiterere ya waveguide kugira ngo rikwirakwize amashusho akomoka ku bice by'urumuri binyuze mu gasanduku kari muri lense. Ibi bigabanya ubunini bwa lense, bigatuma indorerwamo za AR zisa neza n'izisanzwe.
Mu Ukwakira 2024, Meta (yahoze ari Facebook) yatangije ikoreshwa ry'amakuru y'urumuri ya silicon carbide ahujwe na microLED mu ndorerwamo zayo za Orion AR, ikemura ibibazo by'ingenzi mu nzego nko kureba, uburemere, n'ibikoresho by'urumuri. Umuhanga mu bya siyansi ya Meta Pascual Rivera yavuze ko ikoranabuhanga rya silicon carbide waveguide ryahinduye burundu ubwiza bw'indorerwamo za AR, rihindura uburambe kuva ku "matara asa n'umukororombya" kugeza ku "uburambe butuje nk'ubw'igitaramo."
Mu Ukuboza 2024, XINKEHUI yashoboye gukora neza substrate ya mbere ku isi ya silicon carbide imwe ya santimetero 12 ifite ubuziranenge buhanitse, ikaba ari intambwe ikomeye mu bijyanye n'ibikoresho binini. Iri koranabuhanga rizihutisha ikoreshwa rya silicon carbide mu bikoresho bishya nk'indorerwamo za AR n'ibikoresho bishyushya. Urugero, wafer ya silicon carbide ya santimetero 12 ishobora gukora lenses 8-9 z'indorerwamo za AR, bikanoza cyane umusaruro. Dushobora gutanga wafer ya SiC kugira ngo ishyigikire iyo mikoreshereze mu nganda z'indorerwamo za AR.
Vuba aha, ucuruza substrate ya silicon carbide XINKEHUI yafatanyije na sosiyete y’ibikoresho bya micro-nano optoelectronic MOD MICRO-NANO kugira ngo bashyinge umushinga w’ubufatanye wibanda ku iterambere no guteza imbere isoko ry’ikoranabuhanga rya AR diffraction waveguide lens. XINKEHUI, hamwe n’ubuhanga bwayo mu bya tekiniki bya silicon carbide, izatanga substrate nziza za MOD MICRO-NANO, izakoresha ibyiza byayo mu ikoranabuhanga rya micro-nano optique no gutunganya waveguide ya AR kugira ngo irusheho kunoza imikorere ya diffraction waveguide. Ubu bufatanye bwitezweho kwihutisha iterambere ry’ikoranabuhanga mu birahuri bya AR, bigateza imbere intambwe y’inganda igana ku mikorere myiza no ku miterere yoroheje.
Mu imurikagurisha rya SPIE AR|VR|MR ryo mu 2025, MOD MICRO-NANO yamuritse indorerwamo zayo za silicon carbide AR zo mu gisekuru cya kabiri, zipima garama 2.7 gusa kandi zifite ubugari bwa milimetero 0.55 gusa, zoroheje kurusha indorerwamo z'izuba zisanzwe, iha abayikoresha uburambe bwo kwambara budashobora kugaragara, bagera ku gishushanyo "cyoroheje" koko.
Imiterere ya Silicon Carbide mu birahuri bya AR
Mu gikorwa cyo gukora ibyuma bya silicon carbide waveguides, itsinda rya Meta ryatsinze imbogamizi z'ikoranabuhanga ryo gushushanya. Umuyobozi w'ubushakashatsi Nihar Mohanty yasobanuye ko gushushanya ibyuma bya slanted ari ikoranabuhanga ridasanzwe ryo gushushanya rikoresha ibyuma bito bito, rishyiraho imirongo ku nguni igororotse kugira ngo rirusheho guhuza urumuri no gutandukanya neza. Iri terambere ryashyizeho urufatiro rwo gukoresha silicon carbide mu birahuri bya AR.
Indorerwamo za Orion AR za Meta ni uburyo bugaragaza ikoranabuhanga rya silicon carbide muri AR. Ikoresheje ikoranabuhanga rya silicon carbide waveguide, Orion igera ku rwego rwo hejuru rwa dogere 70 kandi igakemura ibibazo nk'ibihuha n'ingaruka z'umukororombya.
Giuseppe Carafiore, umuyobozi w’ikoranabuhanga rya Meta mu bijyanye n’amashusho y’urumuri rwa AR, yavuze ko kuba silicon carbide ifite ubushobozi bwo kuzamuka cyane mu kirere ndetse n’ubushyuhe bituma iba ibikoresho byiza cyane ku birahuri bya AR. Nyuma yo guhitamo ibikoresho, ikibazo gikurikiraho cyari ugukora umurongo w’urumuri, cyane cyane inzira yo gushushanya urumuri rwa slanted kuri grating. Carafiore yasobanuye ko uru ruziga, rushinzwe guhuza urumuri rwinjira n’urusohoka muri lens, rugomba gukoresha umurongo w’urumuri rwa slanted. Imirongo y’urumuri idatondetse neza ahubwo ikwirakwizwa ku nguni ihanamye. Nihar Mohanty yongeyeho ko ari bo ba mbere ku isi bagezeho umurongo w’urumuri rwa slanted ku bikoresho. Mu 2019, Nihar Mohanty n’ikipe ye bubatse umurongo wihariye wo gukora. Mbere y’ibyo, nta bikoresho byari bihari byo gushushanya umurongo w’urumuri rwa silicon carbide, ndetse n’ikoranabuhanga ryari rishoboka hanze ya laboratwari.
Imbogamizi n'amahirwe y'ejo hazaza ya Silicon Carbide
Nubwo karubide ya silikoni igaragaza ubushobozi bukomeye mu ndorerwamo za AR, ikoreshwa ryayo riracyafite imbogamizi nyinshi. Muri iki gihe, ibikoresho bya silikoni bya silikoni birahenze bitewe n'uko bitinda gukura no gutunganywa bigoranye. Urugero, lenzi imwe ya silikoni ya silikoni ya Meta's Orion AR igura amadorari 1.000, bigatuma bigorana guhaza ibyifuzo by'abaguzi. Ariko, bitewe n'iterambere ryihuse ry'inganda zikora imodoka zikoresha amashanyarazi, ikiguzi cya silikoni cya silikoni kirimo kugabanuka buhoro buhoro. Byongeye kandi, iterambere ry'ibikoresho binini (nk'udupira twa santimetero 12) rizakomeza kugabanya ikiguzi no kunoza imikorere.
Ubukana bwinshi bwa silicon carbide nabwo butuma bigorana kuyitunganya, cyane cyane mu gukora imiterere ya micro-nano, bigatuma umusaruro uba muke. Mu gihe kizaza, hamwe n'ubufatanye bwimbitse hagati y'abatanga substrate ya silicon carbide n'abakora micro-nano optique, iki kibazo cyitezweho gukemuka. Ikoreshwa rya silicon carbide mu birahuri bya AR riracyari mu ntangiriro, bisaba amasosiyete menshi gushora imari mu bushakashatsi bwa silicon carbide yo mu rwego rwa optique no guteza imbere ibikoresho. Itsinda rya Meta ryiteze ko abandi bakinnyi bazatangira gukora ibikoresho byabo, uko amasosiyete menshi ashora imari mu bushakashatsi bwa silicon carbide yo mu rwego rwa optique n'ibikoresho, ni ko urwego rw'inganda z'indorerwamo za AR zo mu rwego rwa optique ruzakomera.
