Nhoroondo yetekinoroji yevanhu inogona kuonekwa sekutsvaga "kuvandudza" kusingadzoreki - zvishandiso zvekunze zvinosimudzira kugona kwechisikigo.
Semuenzaniso, moto wakashanda senzira ye "kuwedzera" kugaya, uchiburitsa simba rakawanda rekukura kwehuropi. Redhiyo, yakazvarwa mukupera kwezana remakore rechi19, yakava "tambo yezwi yekunze," ichibvumira manzwi kufamba nekumhanya kwechiedza pasi rese.
Nhasi,AR (Augmented Reality)iri kubuda se "ziso rekunze" - richibatanidza nyika dzepaindaneti nedzechokwadi, richichinja maonero atinoita zvakatipoteredza.
Asi pasinei nekuvimbisa kwekutanga, shanduko yeAR yave kunonoka. Vamwe vagadziri vezvinhu zvitsva vakatsunga kukurumidzisa shanduko iyi.
Musi wa24 Gunyana, Westlake University, yakazivisa kufambira mberi kukuru mu tekinoroji yeAR display.
Nekutsiva girazi rechinyakare kana resin nekabhidhi yesilicon (SiC), vakagadzira magirazi eAR akatetepa zvikuru uye akareruka—rimwe nerimwe richirema chetemagiramu 2.7uye chete0.55 mm ukobvu—matete pane magirazi ezuva akajairika. Magirazi matsva anogonesawokuratidzwa kwemavara akazara (FOV)uye kubvisa "zvinhu zvemuraraungu" zvine mukurumbira zvinobata magirazi ekare eAR.
Utsva uhwu hunogonagadzirisa dhizaini yemaziso eARuye kuunza AR pedyo nekushandiswa kwevatengi vakawanda.
Simba reSilicon Carbide
Sei uchifanira kusarudza silicon carbide yeAR lenses? Nyaya iyi inotanga muna 1893, apo musayendisiti wekuFrance Henri Moissan akawana kristaro inopenya mumienzaniso yemeteorite kubva kuArizona—yakagadzirwa nekabhoni nesilicon. Nhasi inozivikanwa seMoissanite, chinhu ichi chakafanana nematombo anokosha chinodiwa nekuda kwekuwedzera kwayo kupenya uye kupenya kwayo zvichienzaniswa nemadhaimani.
Pakati pezana remakore rechi20, SiC yakabudawo semuchina wemagetsi wechizvarwa chinotevera. Hunhu hwayo hwepamusoro hwekupisa nemagetsi hwakaita kuti ive yakakosha mumotokari dzemagetsi, michina yekutaurirana, uye maseru ezuva.
Zvichienzaniswa nemidziyo yesilicon (300°C max), zvikamu zveSiC zvinoshanda kusvika ku600°C nefrequency yakakwira ka10 uye simba rakawanda. Kupisa kwayo kwakanyanya kunobatsirawo mukutonhora nekukurumidza.
Zvisingawanzoitiki—zvinowanikwa mumameteorite—kugadzirwa kweSiC yekugadzira kwakaoma uye kunodhura. Kurima kristaro ye2 cm chete kunoda kuti 2300°C ishande kwemazuva manomwe. Mushure mekukura, kuomarara kwechinhu ichi kwakaita sedhaimani kunoita kuti kucheka nekugadzirisa kuve kwakaoma.
Kutaura zvazviri, chinangwa chekutanga cherabhoritari yaProf. Qiu Min paWestlake University chaive chekugadzirisa dambudziko iri chaizvo—kugadzira matekiniki akavakirwa palaser ekucheka makristaro eSiC zvinobudirira, zvichivandudza goho uye kuderedza mitengo.
Munguva iyi, timu iyi yakaonawo chimwe chinhu chakasiyana che pure SiC: chiratidzo chinoshamisa che refractive che2.65 uye optical clearness kana isina kuvhurwa—yakanakira AR optics.
Kubudirira Kwacho: Tekinoroji yeDiffractive Waveguide
PaWestlake University'sNanophotonics uye Instrumentation Lab, chikwata chenyanzvi dzemaziso chakatanga kutsvaga mashandisirwo eSiC mumagirazi eAR.
In AR yakavakirwa pakutungamira mafungu emvura, purojekita diki iri parutivi rwemagirazi inoburitsa chiedza munzira yakagadzirwa zvakanaka.Magirati ane saizi shomapa lenzi inopinza chiedza wochitungamirira, uchichiratidza kakawanda usati wachiisa mumaziso emunhu akapfeka.
Kare, nekuda kwegirazi rinoyera zvishoma (rinenge 1.5–2.0), nhungamiro dzemafungu echinyakare dzinodiwazvikamu zvakawanda zvakarongwa—zvichikonzeramagirazi akakora, anoremauye zvinhu zvisingadiwi zvinoonekwa zvakaita se "mapatani emuraraungu" anokonzerwa nekupararira kwechiedza munzvimbo inotonhorera. Zvidziviriro zvekunze zvakawedzerwawo kune lenzi yakawanda.
NaSiC's ultra-high refractive index (2.65), arukoko rumwe chete rwemafunguikozvino zvakakwana kuti mifananidzo ibude nemavara akazara neFOV inodarika 80°—zvinowedzera kaviri kugona kwezvinhu zvemazuva ose. Izvi zvinowedzera zvikuru kugona kwezvinhu zvemazuva osekunyudzwa uye kunaka kwemufananidzoyekutamba mitambo, kuratidza data, uye mashandisirwo ehunyanzvi.
Uyezve, magadzirirwo egridi akanyatsogadzirwa uye kugadziriswa zvakanaka kwazvo kunoderedza mhedzisiro inovhiringidza yerainbow.kufambiswa kwemhepo kwakanyanya kwekupisa, magirazi aya anogona kutobatsira kubvisa kupisa kunokonzerwa nezvinhu zveAR—kugadzirisa rimwe dambudziko mumagirazi eAR madiki.
Kufungazve nezveMitemo yeAR Design
Zvinofadza kuti kubudirira uku kwakatanga nemubvunzo uri nyore kubva kuna Purofesa Qiu:"Muganho we2.0 refractive index unoshanda zvechokwadi here?"
Kwemakore, tsika dzeindasitiri dzaifunga kuti ma refractive indices ari pamusoro pe2.0 aizokonzera kukanganiswa kwemaziso. Nekupikisa chitendero ichi nekushandisa SiC, timu iyi yakavhura mikana mitsva.
Zvino, magirazi eSiC AR emuenzaniso—yakareruka, yakasimba pakupisa, ine mifananidzo yakajeka uye ine mavara akazara—vakagadzirira kukanganisa musika.
Ramangwana
Munyika umo AR ichachinja maonero edu echokwadi munguva pfupi iri kutevera, nyaya iyi yekushandura "dombo rinokosha risingawanzoonekwi" kuita tekinoroji yemaziso inoshanda zvakanyanyahumbowo hwehungwaru hwevanhu.
Kubva pane chinotsiva madhaimani kuenda kune chinhu chitsva cheAR yechizvarwa chinotevera,kabhidhi yesiliconzviri kujekesa nzira yekufambira mberi zvechokwadi.
Nezvedu
TiriXKH, kambani inotungamira mukugadzira mawafer eSilicon Carbide (SiC) nemakristaro eSiC.
Tine hunyanzvi hwekugadzira hwepamusoro uye makore ehunyanzvi, tinopazvinhu zveSiC zvakachena kwazvoyezvigadzirwa zve semiconductor zvechizvarwa chinotevera, optoelectronics, uye matekinoroji ari kubuda eAR/VR.
Pamusoro pekushandiswa kwemaindasitiri, XKH inogadzirawomatombo anokosha eMoissanite (synthetic SiC), inoshandiswa zvakanyanya muzvishongo zvakanaka nekuda kwekubwinya kwazvo uye kugara kwenguva refu.
Kana kuti zvemagetsi emagetsi, optics yepamusoro, kana zvishongo zveumbozhaXKH inopa zvigadzirwa zveSiC zvemhando yepamusoro uye zvakavimbika kuti zvizadzise zvinodiwa nemisika yepasi rose.
