E kitea ana te hītori o te hangarau tangata hei whai tonu i ngā "whakareitanga" - arā, he taputapu o waho e whakarei ake ana i ngā āheinga taiao.
Hei tauira, ko te ahi he pūnaha nakunaku "tāpiri", e tuku ana i te kaha mō te whanaketanga o te roro. Ko te reo irirangi, i whānau i te mutunga o te rautau 19, i huri hei "taura reo o waho", e āhei ai ngā reo ki te haere i te tere o te mārama puta noa i te ao.
I tēnei rā,AR (Motu Whakanuia)kei te puta ake hei "kanohi o waho" - e hono ana i te ao mariko me te ao tūturu, e whakarerekē ana i te tirohanga a tātou ki te taiao e karapoti nei i a tātou.
Ahakoa ngā kupu whakaari i te tīmatanga, kua roa te whanaketanga o te AR i muri i ngā tumanakohanga. Kua whakatau ētahi o ngā kaihanga auaha ki te whakateretere i tēnei panonitanga.
I te 24 o Hepetema, i pānuitia e Te Whare Wānanga o Westlake tētahi putanga nui i roto i te hangarau whakaaturanga AR.
Mā te whakakapi i te karāhe tuku iho, i te kapia rānei kikāpira silicon (SiC), i whakawhanakehia e rātou ngā karaihe AR tino angiangi me te māmā—he tata te taumaha o ia karaihe2.7 karamuā, anake0.55 mm te matotoru—he angiangi ake i ngā mōhiti kanohi noa. Ka taea hoki e ngā karāhe hou tewhakaaturanga whānui-tirohanga (FOV) tae-katoame te whakakore i ngā "taonga āniwaniwa" rongonui e whakararuraru ana i ngā mōhiti AR tuku iho.
Ka taea e tēnei mahi auaha tewhakahou i te hoahoa mōhiti ARā, ka tata ake te whakamahinga o te AR ki te nuinga o ngā kaihoko.
Te Mana o te Silicon Carbide
He aha i whiriwhiria ai te silicon carbide mō ngā karaihe AR? Ka tīmata te kōrero i te tau 1893, i te kitenga o te kaipūtaiao Wīwī a Henri Moissan i tētahi tioata kanapa i roto i ngā tauira meteorite mai i Arizona—he mea hanga ki te waro me te silicon. E mōhiotia ana i ēnei rā ko Moissanite, e arohaina ana tēnei rauemi rite ki te kohatu utu nui nā tōna taupū whakaata teitei ake me tōna kanapa ki te whakatauritea ki ngā taimana.
I waenganui o te rautau 20, i puta mai anō te SiC hei haurua-ā-ira o te whakatupuranga e whai ake nei. Nā ōna āhuatanga wera me te hiko pai rawa atu, kua tino whai hua ai i roto i ngā waka hiko, ngā taputapu whakawhitiwhiti kōrero, me ngā pūtau rā.
Ki te whakatauritea ki ngā taputapu silicon (300°C te mōrahi), ka mahi ngā wāhanga SiC tae atu ki te 600°C me te auau 10x teitei ake me te whai huatanga pūngao nui ake. Ka āwhina hoki tōna kawe wera teitei ki te whakamatao tere.
He mea onge noa iho—e kitea ana i roto i ngā kōhatu rangi—he uaua, he utu nui hoki te hanga SiC horihori. E whitu ngā rā e hiahiatia ana kia whakahaerehia he oumu 2300°C i muri i te tipu, nā te pakeke rite ki te taimana o te rauemi.
Ko te kaupapa matua o te taiwhanga a Ahorangi Qiu Min i Te Whare Wānanga o Westlake ko te whakaoti i tēnei raruraru—te whakawhanake i ngā tikanga e hangai ana ki te taiaho hei tapatapahi pai i ngā tioata SiC, kia tino pai ake ai te hua me te whakaiti i ngā utu.
I roto i tēnei tukanga, i kitea anō e te tīma tētahi atu āhuatanga ahurei o te SiC parakore: he taupū whakaata whakamiharo o te 2.65 me te māramatanga whatu ina tangohia te tāpiringa—he mea tino pai mō ngā whatu AR.
Te Pakaritanga: Te Hangarau Arataki Ngaru Whakarara
I Te Whare Wānanga o WestlakeTaiwhanga Nanophotonics me te Taputapu, ka tīmata tētahi rōpū tohunga tirohanga ki te tūhura me pēhea te whakamahi i te SiC i roto i ngā karāhe AR.
In AR e hangai ana ki te arataki ngaru whakarara, ka tukuna te mārama e tētahi pūwhakaata iti i te taha o ngā mōhiti mā tētahi ara i hangaia kia ātaahua.Ngā whariki nano-tauinekei runga i te arotahi ka whakahoro, ka ārahi i te mārama, ka whakaatahia kia maha ngā wā i mua i te tuku tika atu ki ngā kanohi o te kaimau.
I mua, nā te meate iti o te taupū whakaata o te karāhe (tata ki te 1.5–2.0), e hiahiatia ana ngā arataki ngaru tuku ihongā paparanga maha kua whakarārangihia—ka hua akengā karaihe matotoru, taumahame ngā taonga tirohanga kāore e hiahiatia ana pērā i ngā "tauira āniwaniwa" i puta mai i te wehewehenga o te māramatanga taiao. Ka tāpirihia atu ngā paparanga tiaki o waho ki te matotoru o te arotahi.
KiTe taupū whakaata tino teitei o SiC (2.65), hepaparanga arataki kotahihe rawaka inaianei mō te whakaahua tae katoa me teFOV neke atu i te 80°—whakarei rua i ngā āheinga o ngā rauemi tuku iho. Ka tino whakarei ake tēneite rumaki me te kounga o te ahuamō ngā petipeti, te whakaaturanga raraunga, me ngā tono ngaio.
Heoi anō, mā ngā hoahoa whatanga tika me te tukatuka tino pai ka whakaitihia ngā pānga āniwaniwa whakararuraru. I te whakakotahitanga me ngā SiCkawe wera tino pai, ka taea e ngā karāhe arotahi te āwhina ki te whakamarara i te wera e puta mai ana i ngā wāhanga AR—e whakaoti ana i tētahi atu wero i roto i ngā karāhe AR kiato.
Te Whakaaro Anō i ngā Ture o te Hoahoa AR
He mea whakamīharo, i tīmata tēnei putanga nui i tētahi pātai māmā mai i a Ahorangi Qiu:"Kei te mau tonu te rohenga o te taupū whakaata 2.0?"
Mō ngā tau maha, i whakaarohia e te tikanga ahumahi ko ngā taupū whakaata i runga ake i te 2.0 ka puta he whakapōturitanga whatu. Mā te wero i tēnei whakapono me te whakamahi i te SiC, i huakina e te tīma ngā huarahi hou.
Ināianei, ko te tauira mōhiti SiC AR—he māmā, he pumau ki te pāmahana, he mārama hoki te whakaahua tae katoa—kua rite ki te whakararuraru i te mākete.
Te Ao o Muri Mai
I tēnei ao ka huri te AR i tā tātou tirohanga ki te ao tūturu, ko tēnei kōrero mōte huri i tētahi "kohatu i whānau mai i te wāhi" onge hei hangarau whatu mahi teiteihe tohu mō te auahatanga o te tangata.
Mai i te whakakapinga mō ngā taimana ki te rauemi matatau mō te AR o te whakatipuranga e whai ake nei,karāhe silicone whakamārama ana i te huarahi whakamua.
