Nhoroondo yeruzivo rwevanhu inogona kuwanzoonekwa sekutsvaga kusinganeti kwe "zvinatsiridza" - zvishandiso zvekunze zvinosimudzira kugona kwechisikigo.
Moto, semuenzaniso, wakashanda se "add-on" digestive system, ichisunungura simba rakawanda rekukura kwehuropi. Redhiyo, yakazvarwa mukupera kwezana ramakore rechi 19, yakava “rwonzi rwokunze,” ichibvumira manzwi kufamba nokumhanya kwechiedza kupota pasi.
Nhasi,AR (Augmented Reality)riri kubuda se“ziso rokunze”—rinobatanidza nyika chaidzo uye chaidzo, richishandura maonero atinoita zvakatipoteredza.
Asi zvisinei nevimbiso yekutanga, shanduko yeAR yakasaririra kumashure kwetarisiro. Vamwe vagadziri vakatsunga kukurumidzisa shanduko iyi.
Musi waGunyana 24, Westlake University, yakazivisa budiriro yakakosha muAR kuratidza tekinoroji.
Nekutsiva girazi rechinyakare kana resin nesilicon carbide (SiC), vakagadzira ultra-thin and lightweight AR lenzis-imwe neimwe ichirema zvakafanira2.7 magiramuuye chete0.55 mm mukobvu-kutetepa kudarika magirazi ezuva. Iwo ma lenzi matsva anogonesawowide field-of-view (FOV) full-color displayuye bvisa izvo zvinozivikanwa "murarabungu zvigadzirwa" zvinotambudza magirazi eAR.
Hutsva uhu hwaigonagadzirisa AR eyewear dhizainiuye kuunza AR pedyo nekugamuchirwa kwevatengi vakawanda.
Simba reSilicon Carbide
Sei uchisarudza silicon carbide yeAR lenzi? Nyaya inotanga muna 1893, apo musayendisiti wechiFrench Henri Moissan akawana kristaro inopenya mumasampuli emeteorite kubva kuArizona-yakagadzirwa nekabhoni nesilicon. Inozivikanwa nhasi seMoissanite, iyi gem-yakaita senge inodiwa nekuda kweiyo yepamusoro refractive index uye kupenya kana ichienzaniswa nedhaimani.
Pakati pezana remakore rechi20, SiC yakabudawo semiconductor yechizvarwa chinotevera. Hunhu hwayo hwepamusoro hwekupisa nemagetsi hwakaita kuti ive yakakosha mumotokari dzemagetsi, midziyo yekutaurirana, uye maseru ezuva.
Zvichienzaniswa nemidziyo yesilicon (300°C max), maSiC components anoshanda anosvika 600°C ane 10x yakakwirira frequency uye yakakura kwazvo simba rekushandisa. Yayo yakakwirira yekupisa conductivity inobatsirawo mukukurumidza kutonhora.
Nenzira isingawanzoitiki-kunyanya inowanikwa mumateorite-yakagadzirwa SiC kugadzirwa kwakaoma uye kunodhura. Kukura chete 2 cm crystal kunoda 2300 ° C choto chemazuva manomwe. Mushure mekukura, kuomarara kwedhaimani kunoita kuti kucheka nekugadzirisa kuve dambudziko.
Kutaura zvazviri, chinangwa chepakutanga cheLebhu yaProf Qiu Min kuWestlake University kwaiva kugadzirisa chaizvo dambudziko iri-kugadzira nzira dzelaser-based kuti dzinyatsocheka makristasi eSiC, kuvandudza zvinoshamisa goho uye kuderedza mari.
Munguva iyi, timu yakaonawo imwe yakasarudzika pfuma yeSiC yakachena: inoyevedza refractive index ye2.65 uye kujeka kwemaziso kana isina kubviswa-yakanakira AR optics.
Zvakawanda: Diffraactive Waveguide Technology
KuWestlake UniversityNanophotonics uye Instrumentation Lab, chikwata chenyanzvi dzemaziso chakatanga kuongorora nzira yekushandisa SiC mumalenzi eAR.
In diffractive waveguide-based AR, purojekita diki padivi pemagirazi inoburitsa chiedza kuburikidza nenzira yakanyatsogadzirwa.Nano-scale gratingspa lens patsanura uye tungamira mwenje, uchiratidzira kakawanda usati wainangisa mumaziso eanoripfeka.
Kare, nekuda kweyakaderera refractive index yegirazi (yakatenderedza 1.5-2.0), magadhi esaisai echinyakare anodiwaakawanda akaturikidzana akaturikidzana- zvichikonzeramakobvu, anorema lenziuye zvisingadiwi zvinoonekwa zvekugadzira se "muraraungu mapatani" anokonzerwa nemamiriro ekunze mwenje diffraction. Dziviriro dzekunze dzekunze dzinowedzerwa kune yakawanda lens.
WithSiC's yekupedzisira-yakakwirira refractive index (2.65), asingle waveguide layerikozvino yakwana kune yakazara-ruvara imaging neFOV inopfuura 80 °- kaviri kugona kwezvinhu zvakajairika. Izvi zvinowedzera zvakanyanyakunyudzwa uye kunaka kwemufananidzoyemitambo, kuona data, uye maapplication ehunyanzvi.
Zvakare, chaiwo madhizaini ekugadzira uye ultra-fine processing inoderedza zvinokanganisa muraraungu mhedzisiro. Yakasanganiswa neSiC'sunoshamisa thermal conductivity, ma lenzi anogona kutobatsira kubvisa kupisa kunokonzerwa neAR components-kugadzirisa imwe dambudziko mumagirazi e AR.
Kufunga patsva Mitemo yeAR Dhizaini
Sezvineiwo, budiriro iyi yakatanga nemubvunzo uri nyore kubva kuna Prof. Qiu:"Ko 2.0 refractive index muganho unobata chaizvo?"
Kwemakore, gungano reindasitiri raifungidzira refractive indices pamusoro pe2.0 yaizokonzera kukanganisa kwemaziso. Nekupikisa kutenda uku uye nekusimudzira SiC, timu yakavhura mikana mitsva.
Zvino, iyo prototype SiC AR magirazi-huremu, kugadzikana kwemafuta, nemifananidzo yekiristal-yakajeka yakazara-ruvara-vakagadzirira kukanganisa musika.
Ramangwana
Munyika umo AR ichakurumidza kugadzirisa maonero atinoita chokwadi, iyi nyaya yekushandura "gem-yakazvarwa" isingawanzo kuita tekinoroji yepamusoro-soroufakazi hwoungwaru hwomunhu.
Kubva pakutsiva madhaimondi kune yekubudirira zvinhu zveinotevera-gen AR,silicon carbideiri kuvheneka nzira yekumberi.
Nezvedu
TiriXKH, mugadziri anotungamira anoshanda muSilicon Carbide (SiC) wafers uye SiC makristasi.
Nehunyanzvi hwekugadzira uye makore ehunyanzvi, tinopayakakwirira-kuchena SiC zvinhuyechizvarwa chinotevera semiconductors, optoelectronics, uye ari kubuda AR/VR matekinoroji.
Pamusoro pekushandiswa kwemaindasitiri, XKH inogadzirawopremium Moissanite matombo anokosha (synthetic SiC), inoshandiswa zvakanyanya muzvishongo zvakanakisa nekuda kwekupenya kwazvo uye kugara kwenguva refu.
Kana zvemagetsi emagetsi, advanced optics, kana zvishongo zveumbozha, XKH inopa zvigadzirwa zveSiC zvakavimbika, zvemhando yepamusoro kuti zvizadzise zvinodiwa nemisika yepasi rose.
