Iterambere ryihuse ry’ikoranabuhanga rya Augmented Reality (AR) na Virtual Reality (VR) ririmo gushyira ibintu byinshi ku buryo budasanzwe ku bice by’urumuri. Ishingiro ry’izi sisitemu zigezweho ni ikintu cy’ingenzi: ikirahure cy’ubuziranenge. Uko ibikoresho bigenda birushaho kuba bito, byoroheje, kandi birushaho kuba bito, ibipimo by’ibirahure bizishyigikira bigenda birushaho gukomera.
Ku bashushanya sisitemu z'amatara n'abakora ibikoresho by'ikoranabuhanga, gusobanukirwa izi ngingo z'ikoranabuhanga si ugushaka ibikoresho gusa - ahubwo ni ugutuma habaho icyiciro gitaha cy'ikoranabuhanga ry'ikoranabuhanga. Muri ZHHIMG, duhuza icyuho kiri hagati y'ubumenyi bw'ibikoresho fatizo n'imikorere y'ikoranabuhanga. Dore ibisobanuro by'ingenzi ugomba kumenya mu gihe uhitamo utubati tw'ikirahure two gukoresha muri porogaramu za AR/VR.
Ibikoresho byo mu gice cy'ubutaka n'ibipimo bya Refractive
Guhitamo ibikoresho by'ikirahure bigena inzira y'urumuri n'imiterere y'igikoresho cya nyuma.
- Ikirahure cy’urumuri gifite isura ya Refractive (n > 1.8): Ku byuma bya AR bishingiye ku muyoboro w’amazi, urumuri rugomba guhuzwa neza kandi rukayoborwa binyuze mu mucyo w’imbere. Ikirahure gifite isura ya refractive gitanga moteri nto, zoroheje kandi zifite imiterere migari (FOV).
- Silika Ivanze: Ikoreshwa cyane mu gutunganya na laser ya UV no kuyikoresha bisaba ubushyuhe bukabije. Ifite ubushyuhe buke bwo kwaguka butuma imikorere y'urumuri ikomeza kuba myiza nubwo haba hari urumuri rwinshi.
- Guhuza Ubushyuhe: Muri optique ingana na wafer, substrate y'ikirahure ikunze kuba igomba guhuzwa na sensor za silikoni cyangwa ecran. Guhitamo imiterere y'ikirahure ifite coefficient yo kwagura ubushyuhe ihuye na silikoni (hafi 2.6 × 10⁻⁶/K) ni ingenzi cyane kugira ngo hirindwe kugorama cyangwa gutandukana mu gihe cy'ubushyuhe.
Ubwihangane mu Bipimo n'Ubwiza bw'Ubuso
Mu rwego rwa optike y’urwego rwa wafer, ubuziranenge bupimirwa muri mikoroni na nanometero. Ibipimo bisanzwe by’ibirahure by’ubucuruzi ntabwo bikurikizwa hano.
- Ubugari n'Ubunini: Imiterere isanzwe irimo utubuto twa 200mm na 300mm, dufite ubunini buri hagati ya 0.3mm na 5mm.
- Kwihanganira ubunini: Dukomeza kwihanganira ubunini buto, ubusanzwe ± 5µm, kugira ngo dushobore kubona ibintu bimwe kuri wafer.
- Ihindagurika ry'Ubunini Rusange (TTV): TTV ifite <5µm ni ingenzi mu gukomeza kwibanda no gukumira ihindagurika ry'amatara mu matsinda y'amatara afatanye.
- Ubugari: Kugira ngo hirindwe kwangirika kw'ishusho, umuheto n'ubugari bigomba kugenzurwa kugeza kuri <20µm na <5µm uko bikurikirana.
Irangi ry'ubuso n'ubukonje
Ubwiza bw'ikirahure bugira ingaruka zitaziguye ku ihererekanya ry'urumuri no gukwirakwira kwarwo.
- Ubukana (Ra): Ku bice by'urumuri bya AR VR bifite imikorere myiza, tugera ku gaciro k'ubukana bw'urumuri rwa Ra <1nm. Ubu buryo bworoshye bwa atome bugabanya gukwirakwira k'urumuri n'ibicu, bigatuma habaho itandukaniro rikomeye n'ubusobanuro bwiza.
- Ubwiza bw'ubuso: Dukurikije amahame ya MIL-PRF-13830B, dukunze gutanga ikirahure gifite amanota 40-20 yo gukata cyangwa arenga. Mu buryo bworoshye bwo kwangirika nk'ubuhanga bwa lithography cyangwa laser optics, ndetse n'ibyangiritse munsi y'ubuso bigomba gukurwaho hakoreshejwe uburyo bugezweho bwo gusiga irangi.
Gutunganya no Gusiga Irangi Bigezweho
Ikirahure kibisi ni intangiriro gusa. Imikorere ya wafer igaragazwa n'uburyo itunganywa.
- Gusukura impande ebyiri (DSP): Ni ngombwa cyane ku bikoresho bisaba ubwiza bw'urumuri ku mpande zombi, nk'ibice bigabanya imirasire cyangwa ikirahuri cyo gupfuka kuri sisitemu za LiDAR.
- Imyambaro Idasubiramo Isura (AR): Kugira ngo urumuri rugere ku rugero rwo hejuru (akenshi >98%), hashyirwaho ibishushanyo bya AR by’ubuziranenge. Spectrophotometry ikoreshwa mu kugenzura imikorere y’ibishushanyo muri spectrum igaragara (400-700nm) cyangwa uburebure bwihariye bwa laser (urugero, 940nm kugira ngo harebwe 3D).
- Gukata no Gushushanya hakoreshejwe Laser: Ku bijyanye n'imiterere yihariye y'ibishushanyo cyangwa optique idakora nk'uruziga, guca hakoreshejwe laser bitanga impande nziza kandi zidafite uduce duto, bigagabanya gukenera gusya impande nyinshi.
Kugereranya Ubwoko bw'Ikirahure kuri AR/VR
| Igipimo | Ikirahure gifite uburebure bunini | Silika ivanze | Borofloat / Alkali-Aluminosilicate |
|---|---|---|---|
| Igipimo cy'ikirahure (nd) | > 1.80 | ~ 1.46 | ~ 1.52 |
| Kwaguka k'ubushyuhe | Iringaniye | Hasi cyane | Hasi |
| Porogaramu y'ibanze | Ibikoresho bihuza Waveguide | Udupfukamunwa twa UV / Udupfukamunwa | Ikirahure gipfundikiye / Ibikoresho byo gupima |
| Akamaro k'ingenzi | Guhindura ibintu mu buryo buto | Guhagarara neza k'ubushyuhe | Ikiguzi / Kuramba |
Ubumenyi bw'Ibintu n'Ubuziranenge
Kugira ngo umenye neza ibi bisabwa bisaba ubuziranenge buhanitse. Dukoresha interferometry kugira ngo tumenye ubugari n'ubugari bw'izuba ku buso bwose bwa wafer. Kugira ngo harebwe neza irangi, spectrophotometers zipima uburyo bwo kohereza no gusubiza urumuri ku mfuruka zitandukanye (AOI).
Waba urimo gutegura module zo kumenya 3D kuri telefoni zigendanwa cyangwa se uduce duto two gupima imiterere y'amatara ku birahuri bya AR, ubwiza bw'aho utuye bugena aho imikorere ya sisitemu yawe igarukira.
Gukorana na ZHHIMG
Muri ZHHIMG, twibanda ku gukora utubati tw’ibirahure tw’ubuziranenge bujyanye n’ibyo urwego rw’amatara rukeneye. Kuva ku guhitamo ibikoresho kugeza ku gusiga irangi rya nyuma, dutanga ibisubizo biva ku mpera kugeza ku mpera bigufasha kugera ku mbibi z’ibyo bishoboka muri AR na VR.
Witeguye kunoza imiterere yawe y'amatara?
