Kusintha kwachangu kwa ukadaulo wa Augmented Reality (AR) ndi Virtual Reality (VR) kukuyika zofunikira kwambiri pazinthu zowunikira. Pakati pa makina apamwamba awa pali chinthu chofunikira kwambiri: galasi lolondola. Pamene zipangizo zikukhala zopyapyala, zopepuka, komanso zozama kwambiri, zofunikira za magalasi omwe amathandizira zikukhala zovuta kwambiri.
Kwa opanga makina opangira kuwala ndi opanga, kumvetsetsa mfundo zaukadaulo izi sikuti kungofuna kupeza zinthu zokha—komanso kulola mbadwo wotsatira wa makompyuta ozungulira. Ku ZHHIMG, timalumikiza kusiyana pakati pa sayansi ya zinthu zopangira ndi magwiridwe antchito a kuwala. Nazi mfundo zofunika zomwe muyenera kudziwa posankha ma wafer agalasi a mapulogalamu a AR/VR.
Zinthu Zoyambira ndi Chizindikiro Chowongolera
Kusankha magalasi kumatanthauza njira yowunikira komanso mawonekedwe a chipangizo chomaliza.
- Galasi Lokhala ndi Refractive-Index (n > 1.8): Pa zowonetsera za AR zochokera ku mafunde, kuwala kuyenera kulumikizidwa bwino ndikuwongoleredwa kudzera mu kuwunikira konse kwamkati. Galasi Lokhala ndi Refractive-Index limalola mainjini ang'onoang'ono, opepuka komanso malo ambiri owonera (FOV).
- Silika Yosakanikirana: Imagwiritsidwa ntchito popanga laser ya UV komanso kugwiritsa ntchito komwe kumafuna kukhazikika kwa kutentha kwambiri. Kuchuluka kwake kochepa kwa kutentha kumatsimikizira kuti magwiridwe antchito a kuwala amakhalabe ofanana ngakhale atakhala ndi kuwala kwamphamvu kwambiri.
- Kufananiza Kutentha: Mu ma optics a wafer-level, galasi substrate nthawi zambiri limafunika kulumikizidwa ku masensa a silicon kapena zowonetsera. Kusankha kapangidwe ka galasi komwe kali ndi thermal expansion coefficient yomwe imagwirizana ndi silicon (pafupifupi 2.6 × 10⁻⁶/K) ndikofunikira kwambiri kuti mupewe kupindika kapena kusweka kwa denga panthawi ya kutentha.
Kulekerera kwa Miyeso ndi Ubwino Wapamwamba
Mu gawo la ma optics a wafer level, kulondola kumayesedwa mu ma microns ndi nanometers. Ma specifications a galasi wamba sagwira ntchito pano.
- Kukula ndi Kukhuthala: Mawonekedwe ofala amakhala ndi ma wafer a 200mm ndi 300mm, okhala ndi makulidwe kuyambira 0.3mm mpaka 5mm.
- Kulekerera Kunenepa: Timasunga kulekerera kolimba, nthawi zambiri ± 5µm, kuti tiwonetsetse kuti chikwamacho chili chofanana.
- Kusiyanasiyana Konse kwa Makulidwe (TTV): TTV ya <5µm ndiyofunikira kuti isunge kukhazikika ndikuletsa kusokonekera kwa kuwala m'magawo ophatikizika a kuwala.
- Kusalala: Kuti chithunzi chisasokonezeke, uta ndi kupindika ziyenera kulamulidwa mpaka <20µm ndi <5µm motsatana.
Kumaliza Pamwamba ndi Kuuma
Ubwino wa pamwamba pa galasi umakhudza mwachindunji kutumiza ndi kufalikira kwa kuwala.
- Kukhwima (Ra): Pazigawo zowunikira za AR VR zomwe zimagwira ntchito bwino kwambiri, timapeza kuchuluka kwa kukhwima pamwamba pa Ra <1nm. Kusalala kwapafupi ndi atomiki kumeneku kumachepetsa kufalikira kwa kuwala ndi chifunga, zomwe zimapangitsa kuti kusiyana kwakukulu ndi kumveka bwino.
- Ubwino wa Pamwamba: Potsatira miyezo ya MIL-PRF-13830B, nthawi zambiri timapereka magalasi okhala ndi kukanda kwa 40-20 kapena kupitirira apo. Mu ntchito zomwe zimakhudzidwa ndi zolakwika monga lithography kapena laser optics, ngakhale kuwonongeka kwa pansi pa nthaka kuyenera kuchotsedwa pogwiritsa ntchito njira zapamwamba zopukutira.
Kukonza ndi Kuphimba Zapamwamba
Galasi losaphika ndi chiyambi chabe. Kagwiridwe ka ntchito ka wafer kamatanthauzidwa ndi momwe imagwiritsidwira ntchito.
- Kupukuta Mbali Ziwiri (DSP): Kofunikira pa ntchito zomwe zimafuna kuwala kowala mbali zonse ziwiri, monga zopatulira za beam kapena galasi lophimba makina a LiDAR.
- Zophimba Zosawala (AR): Kuti kuwala kupitirire kwambiri (nthawi zambiri >98%), zophimba zolondola za AR zimayikidwa. Spectrophotometry imagwiritsidwa ntchito kutsimikizira magwiridwe antchito a zophimba pa spectrum yowoneka (400-700nm) kapena mafunde enaake a laser (monga, 940nm ya 3D sensing).
- Kudula ndi Kupanga Mawonekedwe a Laser: Pa ma geometries apadera kapena ma optics osazungulira, kudula kwa laser kumapereka m'mbali zoyera komanso zopanda ming'alu yaying'ono, zomwe zimachepetsa kufunikira kopera m'mphepete kwambiri.
Kuyerekeza Mitundu ya Magalasi ya AR/VR
| Chizindikiro | Galasi Lokhala ndi Zizindikiro Zapamwamba | Silika Yosakanizidwa | Borofloat / Alkali-Aluminosilicate |
|---|---|---|---|
| Chizindikiro Chowunikira (nd) | > 1.80 | ~ 1.46 | ~ 1.52 |
| Kukula kwa Kutentha | Wocheperako | Zochepa Kwambiri | Zochepa |
| Kugwiritsa Ntchito Koyamba | Zosakaniza za Waveguide | Ma UV Optics / Zophimba Masamba | Chivundikiro cha Galasi / Masensa |
| Ubwino Waukulu | Kuchepetsa mphamvu ya thupi | Kukhazikika kwa Kutentha | Mtengo / Kukhalitsa |
Metrology ndi Chitsimikizo Cha Ubwino
Kutsimikizira izi kumafuna metrology yapamwamba kwambiri. Timagwiritsa ntchito interferometry kuti tipeze kusalala ndi TTV pamwamba pa wafer yonse. Kuti titsimikizire chophimba, ma spectrophotometer amayesa kutumiza ndi kuwunikira pa ma angles osiyanasiyana a zochitika (AOI).
Kaya mukupanga ma module ozindikira a 3D a mafoni a m'manja kapena ma waveguide ovuta a diffractive a magalasi a AR, ubwino wa substrate yanu umatsimikizira malire a magwiridwe antchito a makina anu.
Gwirizanani ndi ZHHIMG
Ku ZHHIMG, timapanga ma wafer agalasi olondola omwe amakwaniritsa zofunikira za makampani opanga kuwala. Kuyambira kusankha zinthu mpaka kuphimba komaliza, timapereka mayankho ochokera kumapeto mpaka kumapeto omwe amakuthandizani kukankhira malire a zomwe zingatheke mu AR ndi VR.
Kodi mwakonzeka kukonza kapangidwe kanu ka kuwala?
