I te tere o te whanaketanga o te hangarau mooni whakanuia (AR), ko ngā mōhiti atamai, hei kaikawe nui o te hangarau AR, kei te neke haere mai i te ariā ki te mooni. Heoi, kei te pā tonu te whānui o te whakamahinga o ngā mōhiti atamai ki ngā wero hangarau maha, inā koa mō te hangarau whakaatu, te taumaha, te whakamarara wera, me te mahi whatu. I ngā tau tata nei, kua whakamahia whānuitia te silicon carbide (SiC), hei rauemi hou, i roto i ngā taputapu me ngā kōwae hiko. Kei te uru atu inaianei ki te mara mōhiti AR hei rauemi matua. Ko te taupū whakaata teitei o te silicon carbide, ngā āhuatanga whakamarara wera pai rawa atu, me te pakeke teitei, me ētahi atu āhuatanga, e whakaatu ana i te kaha nui mō te tono i roto i te hangarau whakaatu, te hoahoa mama, me te whakamarara wera o ngā mōhiti AR. Ka taea e mātou te whakaratoWafer SiC, he mea nui tēnei hei whakapai ake i ēnei wāhanga. Kei raro nei, ka tūhuratia e mātou me pēhea e taea ai e te silicon carbide te kawe mai i ngā huringa hou ki ngā mōhiti atamai mai i ngā āhuatanga o ōna āhuatanga, ngā whanaketanga hangarau, ngā tono mākete, me ngā tirohanga ā-muri.
Ngā Āhuatanga me ngā Painga o te Silicon Carbide
He rauemi haurua-ā-rohe whānui te karawiti silicon, ā, he tino pai ōna āhuatanga pērā i te pakeketanga teitei, te kawe wera teitei, me te taupū whakaata teitei. Mā ēnei āhuatanga ka nui te kaha mō te whakamahi i roto i ngā taputapu hiko, ngā taputapu whatu, me te whakahaere wera. Ina koa i roto i te mara o ngā mōhiti atamai, ko ngā painga o te karawiti silicon e whakaatahia ana i roto i ngā āhuatanga e whai ake nei:
Teitei o te Taupū Whakaata: Ko te taupū whakaata o te karāhe silicon he neke atu i te 2.6, he teitei ake i ngā rauemi tuku iho pēnei i te kapia (1.51-1.74) me te karāhe (1.5-1.9). Ko te tikanga o te taupū whakaata teitei ka taea e te karāhe silicon te aukati i te horapa o te mārama, ka whakaiti i te ngaronga o te pūngao mārama, ā, ka whakapai ake i te kanapa o te whakaaturanga me te tirohanga whānui (FOV). Hei tauira, ka whakamahia e ngā mōhiti Orion AR a Meta te hangarau arataki ngaru karāhe silicon, ka tutuki ai te tirohanga whānui 70-tohu, he nui ake i te tirohanga whānui 40-tohu o ngā rauemi karāhe tuku iho.
He Tino Pai te Whakamarara Wera: He rau ngā wā he nui ake te kawe wera o te karāhe silicon carbide i tō te karāhe noa, e āhei ai te kawe wera tere. He take matua te whakamarara wera mō ngā mōhiti AR, inā koa i ngā whakaaturanga kanapa teitei me te whakamahinga roa. Ka taea e ngā karāhe silicon carbide te whakawhiti tere i te wera i hangaia e ngā wāhanga whatu, e whakarei ake ana i te pumau me te roa o te ora o te taputapu. Ka taea e mātou te whakarato i te anga SiC e whakarite ana i te whakahaere wera whai hua i roto i aua tono.
Te Pakari me te Ātete ki te Paka: Ko te karawiti silicon tētahi o ngā rauemi tino pakari e mōhiotia ana, tuarua i te taimana. Nā tēnei ka ātete ake te karawiti silicon ki te paka, ā, he pai mō te whakamahi i ia rā. He rerekē, he ngāwari ake te karawarawa o ngā rauemi karāhe me te kapia, ka pā ki te wheako o te kaiwhakamahi.
Pānga Ārai-Āniwaniwa: Ko ngā rauemi karāhe tuku iho i roto i ngā mōhiti AR ka puta he pānga āniwaniwa, ka whakaata te mārama taiao mai i te mata o te arataki ngaru, ka hangaia he tauira mārama tae hihiri. Ka taea e te karawiti silicon te whakakore i tēnei raruraru mā te arotau i te hanganga whatanga, ka whakapai ake i te kounga whakaaturanga me te whakakore i te pānga āniwaniwa i puta mai i ngā whakaata o te mārama taiao i runga i te mata o te arataki ngaru.
Ngā Ahunga Hou o te Hangarau o te Silicon Carbide i roto i ngā Mōhiti AR
I ngā tau tata nei, ko ngā whanaketanga hangarau o te silicon carbide i roto i ngā mōhiti AR kua aro nui ki te whanaketanga o ngā karāhe arataki ngaru whakarara. Ko te arataki ngaru whakarara he hangarau whakaatu e whakakotahi ana i te āhuatanga whakarara o te mārama me ngā hanganga arataki ngaru hei hora i ngā whakaahua i hangaia e ngā wāhanga whatu mā roto i te whatanga o te karāhe. Mā tēnei ka whakaitihia te matotoru o te karāhe, ka tata ake te āhua o ngā mōhiti AR ki ngā mōhiti noa.
I te marama o Oketopa 2024, i whakaurua e Meta (i mua ko Facebook) te whakamahinga o ngā arataki ngaru kua whakairohia ki te silicon carbide me ngā microLED i roto i āna mōhiti Orion AR, hei whakaoti i ngā arai matua i roto i ngā mara pēnei i te tirohanga whānui, te taumaha, me ngā taonga whatu. I kī te kaipūtaiao whatu a Meta, a Pascual Rivera, nā te hangarau arataki ngaru silicon carbide i tino whakarerekē te kounga whakaaturanga o ngā mōhiti AR, i huri ai te wheako mai i ngā "ira rama āniwaniwa rite ki te pōro disco" ki tētahi "wheako marino rite ki te whare kōnohete."
I te marama o Tīhema 2024, i angitu a XINKEHUI ki te whakawhanake i te papa tuatahi o te ao mō te karaihe kotahi, he 12-inihi te roa, he mea hanga ki te silicon carbide, he mea whakamātao, he mea nui tēnei i roto i te ao o ngā papa rahi. Mā tēnei hangarau ka tere ake te whakamahinga o te silicon carbide i roto i ngā whakamahinga hou pēnei i ngā karāhe AR me ngā totohu wera. Hei tauira, ka taea e te papa silicon carbide 12-inihi te whakaputa i te 8-9 takirua o ngā karāhe AR, ka nui ake te pai o te whakaputa. Ka taea e mātou te whakarato i te papa SiC hei tautoko i aua whakamahinga i roto i te umanga karāhe AR.
Nō nā tata nei, i mahi tahi te kaiwhakarato papa whakarewa silicon carbide a XINKEHUI me te kamupene taputapu optoelectronic micro-nano a MOD MICRO-NANO ki te whakatū i tētahi hononga tahi e arotahi ana ki te whakawhanake me te whakatairanga mākete o te hangarau arotahi ngaru diffraction AR. Ka whakaratohia e XINKEHUI, me ōna tohungatanga hangarau i roto i ngā papa whakarewa silicon carbide, he papa whakarewa kounga teitei mō MOD MICRO-NANO, ka whakamahi i ōna painga i roto i te hangarau whatu micro-nano me te tukatuka ara whakarewa AR hei whakapai ake i te mahi a ngā ara whakarewa diffraction. E matapaetia ana ka tere ake te whanaketanga hangarau o ngā mōhiti AR i tēnei mahi tahi, ka whakatairanga i te nekehanga o te umanga ki te mahi teitei ake me ngā hoahoa mama ake.
I te whakaaturanga SPIE AR|VR|MR i te tau 2025, i whakaatu a MOD MICRO-NANO i ana karaihe mōhiti AR silicon carbide o te whakatipuranga tuarua, he 2.7 karamu anake te taumaha, ā, he 0.55 mirimita te matotoru, he mama ake i ngā mōhiti kanohi noa, e tuku ana i tētahi wheako mau e tata kore e kitea, e tutuki ai he hoahoa "māmā" tino.
Ngā Take Whakamahinga o te Silicon Carbide i roto i ngā Mōhiti AR
I roto i te tukanga hanga o ngā arataki ngaru silicon carbide, i wikitoria te tīma a Meta i ngā wero o te hangarau whakairo whakarara. I whakamārama te kaiwhakahaere rangahau a Nihar Mohanty ko te whakairo whakarara he hangarau whao kore-tuku iho e whakairo ana i ngā rārangi i te koki whakarara hei whakapai ake i te hononga mārama me te whai huatanga o te wetewete. Nā tēnei putanga hou i whakatakoto te turanga mō te whakamahinga nui o te silicon carbide i roto i ngā mōhiti AR.
Ko ngā mōhiti Orion AR a Meta he tono māngai mō te hangarau silicon carbide i roto i te AR. Mā te whakamahi i te hangarau arataki ngaru silicon carbide, ka tutuki i a Orion he tirohanga whānui 70-tohu, ā, ka aro pai ki ngā take pēnei i te wairua me te pānga āniwaniwa.
I kī a Giuseppe Carafiore, te kaiārahi hangarau arataki ngaru AR o Meta, nā te teitei o te taupū whakaata me te kawe wera o te silicon carbide he mea tino pai mō ngā mōhiti AR. Whai muri i te whiriwhiri i te rauemi, ko te wero i muri mai ko te whakawhanake i te arataki ngaru, inā koa ko te tukanga whakairo whakarara mō te whatu. I whakamārama a Carafiore me whakamahi te whatu whakarara, e hono ana i te mārama ki roto, ki waho hoki i te arotahi. Kāore ngā rārangi whakairo i whakaritea poutū engari ka tohatohahia ki te koki whakarara. I tāpiri atu a Nihar Mohanty ko rātou te tīma tuatahi o te ao ki te whakatutuki i te whakairo whakarara tika ki runga i ngā taputapu. I te tau 2019, i hanga e Nihar Mohanty me tana tīma he raina whakaputa motuhake. I mua atu i tērā, kāore he taputapu e wātea ana hei whakairo i ngā arataki ngaru silicon carbide, kāore hoki i taea te hangarau i waho o te taiwhanga.
Ngā Wero me ngā Tūmanako o te Silicon Carbide
Ahakoa he nui te kaha o te karāhe silicon carbide i roto i ngā mōhiti AR, he maha tonu ngā wero e pā ana ki tōna whakamahinga. I tēnei wā, he utu nui te rauemi silicon carbide nā te puhoi o te tipu me te uaua o te tukatuka. Hei tauira, ko te utu mō te karāhe silicon carbide kotahi mō ngā mōhiti Orion AR a Meta he $1,000, he uaua ki te whakatutuki i ngā hiahia o te mākete kaihoko. Heoi, i te tere o te whanaketanga o te umanga waka hiko, kei te heke haere te utu o te silicon carbide. Hei tāpiri, ko te whanaketanga o ngā papa nui (pēnei i ngā anga 12-inihi) ka akiaki ake i te whakaiti i ngā utu me te whakapai ake i te whai huatanga.
Nā te pakeketanga nui o te silicon carbide, he uaua hoki te tukatuka, inā koa i roto i te hanganga hanganga moroiti-nano, ka iti ake te hua. I te heke mai, me te mahi tahi hohonu ake i waenga i ngā kaiwhakarato papa silicon carbide me ngā kaihanga whatu moroiti-nano, e tumanakohia ana ka whakatauhia tēnei take. Kei te tīmatanga tonu te whakamahinga o te silicon carbide i roto i ngā mōhiti AR, me nui ake ngā kamupene ki te haumi ki te rangahau me te whakawhanake taputapu silicon carbide kounga-whatu. E tumanako ana te tīma a Meta kia tīmata ētahi atu kaihanga ki te whakawhanake i ā rātou ake taputapu, i te mea ka nui ake te haumi a ngā kamupene ki te rangahau me ngā taputapu silicon carbide kounga-whatu, ka kaha ake te pūnaha ahumahi mōhiti AR kounga-kiritaki.
Whakamutunga
Ko te karawiti silicon, me tōna taupū whakaata teitei, te tino pai o te tohatoha wera, me te pakeke teitei, kei te noho hei rauemi matua i roto i te mara o ngā mōhiti AR. Mai i te mahi tahi a XINKEHUI me MOD MICRO-NANO ki te tono angitu o te karawiti silicon i roto i ngā mōhiti Orion AR a Meta, kua tino whakaatuhia te kaha o te karawiti silicon i roto i ngā mōhiti atamai. Ahakoa ngā wero pēnei i te utu me ngā arai hangarau, i te pakeke haere o te mekameka ahumahi me te haere tonu o te hangarau ki te ahu whakamua, e tumanakohia ana ka tiaho te karawiti silicon i roto i te mara o ngā mōhiti AR, ka akiaki i ngā mōhiti atamai ki te mahi teitei ake, te taumaha mama ake, me te whakamahinga whānui. I te heke mai, ka noho pea te karawiti silicon hei rauemi matua i roto i te umanga AR, ka arahi i tētahi wā hou o ngā mōhiti atamai.
Kāore te pūmanawa o te silicon carbide i te herea noa ki ngā mōhiti AR; he nui hoki ngā tūmanakohanga mō āna tono ā-umanga i roto i ngā hikohiko me ngā photonics. Hei tauira, kei te tūhuratia te tono o te silicon carbide i roto i te rorohiko irahiko me ngā taputapu hiko mana-teitei. I te whanaketanga o te hangarau me te hekenga o ngā utu, e matapaetia ana ka whai wāhi nui te silicon carbide ki ngā mara maha atu, ka tere ake te whanaketanga o ngā ahumahi e pā ana. Ka taea e mātou te whakarato i te wafer SiC mō ngā tono maha, hei tautoko i ngā whanaketanga i roto i te hangarau AR me tua atu.
