Ukuthuthuka okusheshayo kobuchwepheshe be-Augmented Reality (AR) kanye ne-Virtual Reality (VR) kubeka izidingo ezingakaze zibonwe ezingxenyeni ze-optical. Enhliziyweni yalezi zinhlelo ezithuthukisiwe kukhona isici esibalulekile: i-wafer yengilazi enembile. Njengoba amadivayisi eba mancane, alula, futhi ecwilisa kakhulu, imininingwane yezingxenye zengilazi eziwasekelayo iya ngokuya iba nzima.
Kubaklami bezinhlelo ze-optical kanye nabakhiqizi, ukuqonda la ma-nuances obuchwepheshe akukhona nje ukuthola izinto zokwakha—kumayelana nokuvumela isizukulwane esilandelayo sokubala kwendawo. Kwa-ZHHIMG, sihlanganisa igebe phakathi kwesayensi yezinto zokwakha kanye nokusebenza kwe-optical. Nazi izici ezibalulekile okudingeka uzazi lapho ukhetha ama-glass wafers ezinhlelo zokusebenza ze-AR/VR.
Izinto Ezingaphansi kanye ne-Refractive Index
Ukukhethwa kwezinto zengilazi kunquma indlela yokukhanya kanye nesici sokwakheka kwedivayisi yokugcina.
- Ingilazi Enenkomba Ephakeme (n > 1.8): Kuma-AR display asekelwe ku-waveguide, ukukhanya kudinga ukuhlanganiswa kahle futhi kuqondiswe ngokukhanya kwangaphakathi okuphelele. Ingilazi enenkomba ephezulu ivumela izinjini ezincane nezikhanyayo kanye nezinkambu ezibanzi zokubuka (FOV).
- I-Fused Silica: Ikhethwa kakhulu ekucutshungulweni kwe-laser ye-UV kanye nezinhlelo zokusebenza ezidinga ukuzinza okukhulu kokushisa. I-coefficient yayo yokwandisa ukushisa okuphansi iqinisekisa ukuthi ukusebenza kwe-optical kuhlala kufana ngisho nangaphansi kokukhanya okunamandla aphezulu.
- Ukufaniswa Kokushisa: Kuma-optics asezingeni le-wafer, i-substrate yengilazi ivame ukudinga ukuboshwa kuma-sensor e-silicon noma kuma-display. Ukukhetha ukwakheka kwengilazi okune-coefficient yokwandisa ukushisa efana ne-silicon (cishe 2.6 × 10⁻⁶/K) kubalulekile ukuvimbela ukugoba noma ukuhlukana ngesikhathi sokujikeleza kokushisa.
Ukubekezelelana Okulinganiselwe kanye Nekhwalithi Yomphezulu
Emkhakheni we-wafer level optics, ukunemba kulinganiswa ngama-micron nama-nanometer. Imininingwane ejwayelekile yengilazi yezentengiselwano ayisebenzi lapha.
- Ububanzi Nobukhulu: Amafomethi avamile afaka phakathi ama-wafer angu-200mm no-300mm, anobukhulu obusukela ku-0.3mm kuya ku-5mm.
- Ukubekezelela Ubukhulu: Sigcina ukubekezelelana okuqinile, ngokuvamile okungu-±5µm, ukuqinisekisa ukufana kuyo yonke i-wafer.
- Ukwehlukahluka Kobukhulu Obuphelele (TTV): I-TTV engu-<5µm ibalulekile ekugcineni ukugxila nokuvimbela ukuphazamiseka kwe-optical kuma-stacked optical assembly.
- Ukuthamba: Ukuze kuvinjelwe ukuphambuka kwesithombe, umnsalo kanye nokugoba kumele kulawulwe ku-<20µm kanye <5µm ngokulandelana.
Ukuqeda Okungaphezulu Nokuhluzeka
Ikhwalithi engaphezulu yengilazi ithinta ngqo ukudluliswa kokukhanya kanye nokuhlakazeka.
- Ubulukhuni (Ra): Ngezingxenye ze-AR VR ezibonakalayo ezisebenza kahle kakhulu, sifinyelela amanani obulukhuni bomphezulu we-Ra <1nm. Lokhu kushelela okucishe kube yi-athomu kunciphisa ukusabalala kokukhanya kanye nomswakama, okuqinisekisa ukugqama okuphezulu nokucaca.
- Ikhwalithi Yomphezulu: Ngokunamathela ezindinganisweni ze-MIL-PRF-13830B, sivame ukunikeza ingilazi isilinganiso sokuklwebheka esingu-40-20 noma ngaphezulu. Ezinhlelweni ezibucayi njengeziphambeko njenge-lithography noma i-laser optics, ngisho nomonakalo ongaphansi komhlaba kumele ususwe ngamasu okupholisha athuthukile.
Ukucubungula Okuthuthukisiwe Nokumboza
Ingilazi eluhlaza iyisiqalo nje. Ukusebenza kwe-wafer kuchazwa ngokucutshungulwa kwayo.
- Ukupholisha Okukabili (i-DSP): Kubalulekile ezinhlelweni zokusebenza ezidinga ukucaca okubonakalayo kuzo zombili izinhlangothi, njengezihlukanisi ze-beam noma ingilazi yokumboza yezinhlelo ze-LiDAR.
- Izembozo Ezingabonisi Ukukhanya (AR): Ukuze kukhuliswe ukudluliswa kokukhanya (ngokuvamile >98%), kufakwa izembozo ze-AR ezinembile. I-Spectrophotometry isetshenziselwa ukuqinisekisa ukusebenza kwezembozo kulo lonke i-spectrum ebonakalayo (400-700nm) noma amaza athile e-laser (isb., 940nm yokuzwa kwe-3D).
- Ukusika Nokubumba Nge-Laser: Kumajiyometri enziwe ngokwezifiso noma ama-optics angewona ayindilinga, ukusika nge-laser kunikeza imiphetho ehlanzekile enokuphambuka okuncane, kunciphisa isidingo sokugaya imiphetho kakhulu.
Ukuqhathaniswa Kwezinhlobo Zengilazi ze-AR/VR
| Ipharamitha | Ingilazi Enenkomba Ephakeme | I-Silica Ehlanganisiwe | I-Borofloat / Alkali-Aluminosilicate |
|---|---|---|---|
| Inkomba Yokubukeza (nd) | > 1.80 | ~ 1.46 | ~ 1.52 |
| Ukwanda Kokushisa | Okumaphakathi | Okuphansi Kakhulu | Phansi |

| Inzuzo Eyinhloko | Ukwenziwa kube kuncane | Ukuzinza Kokushisa | Izindleko/Ukuqina |
I-Metrology kanye ne-Quality Assurance
Ukuqinisekisa lezi zincazelo kudinga i-metrology yesimanje. Sisebenzisa i-interferometry ukulinganisa ukuthamba kanye ne-TTV kulo lonke ubuso be-wafer. Ukuze kuqinisekiswe ukumbozwa, ama-spectrophotometer alinganisa ukudluliselwa kanye nokubonakaliswa ngama-engeli ahlukahlukene okwenzeka (i-AOI).
Kungakhathaliseki ukuthi uthuthukisa amamojula okuzwa e-3D kuma-smartphone noma ama-waveguide ayinkimbinkimbi okuhambisa amanzi ezingilazini ze-AR, ikhwalithi ye-substrate yakho ichaza umkhawulo wokusebenza kwesistimu yakho.
Hlanganyela ne-ZHHIMG
Kwa-ZHHIMG, singochwepheshe ekukhiqizeni ama-wafer engilazi anembile ahlangabezana nezidingo eziqinile zemboni ye-optical. Kusukela ekukhetheni izinto kuya ekumbozeni kokugcina, sinikeza izixazululo ezisuka ekugcineni ziye ekugcineni ezikusiza ukuthi udlule imingcele yalokho okungenzeka ku-AR kanye ne-VR.
Ukulungele ukwenza ngcono umklamo wakho we-optical?
