Kushanduka-shanduka kwehunyanzvi hweAugmented Reality (AR) neVirtual Reality (VR) kuri kuwedzera kukosha kwezvinhu zve optical. Pakati pezvinhu izvi zvepamusoro pane chinhu chakakosha: girazi regirazi rakagadzirwa zvakanaka. Sezvo michina ichiva mitete, yakareruka, uye inonyudza zvakanyanya, zvinodiwa zvemagirazi zvinovatsigira zviri kuramba zvichiwedzera kuomarara.
Kune vagadziri vemaoptical system nevagadziri, kunzwisisa ma "technical nuances" aya hakusi kungotsvaga zvinhu chete - asi kunobatsira chizvarwa chinotevera che "spatial computing". PaZHHIMG, tinobatanidza musiyano uripo pakati pe "raw material science" ne "optical performance". Heano ma "specifications" akakosha aunofanira kuziva paunenge uchisarudza ma "glass wafers" ekushandisa AR/VR.
Substrate Material uye Refractive Index
Kusarudzwa kwezvinhu zvegirazi kunotungamira nzira yekuona uye chimiro chechinhu chekupedzisira.
- Girazi reHigh-Refractive-Index (n > 1.8): Kune mawaveguide-based AR displays, chiedza chinofanira kubatanidzwa zvinobudirira uye kutungamirirwa kuburikidza nekutarisa kwemukati kwese. Girazi reHigh-Index rinobvumira mainjini madiki, akareruka uye nzvimbo dzakafara dzekuona (FOV).
- Silica Yakasanganiswa: Inoshandiswa pakugadzirisa nelaser yeUV uye mashandisirwo ayo anoda kugadzikana kwakanyanya kwekupisa. Kuwanda kwayo kwekupisa kwakaderera kunoita kuti mashandiro emaziso arambe akafanana kunyangwe kana paine chiedza chine simba guru.
- Kufananidza Kupisa: Muma optics ane mwero wewafer, girazi rinowanzo fanirwa kusungirirwa kuma sensors esilicon kana ma displays. Kusarudza girazi rine thermal expansion coefficient inoenderana nesilicon (inenge 2.6 × 10⁻⁶/K) kwakakosha kudzivirira kutenderera kana kupatsanurwa panguva yekuchinja kwekushisa.
Kushivirira Kwemativi uye Hunhu Hwepamusoro
Munyaya yewafer level optics, kunyatsojeka kunoyerwa muma microns nema nanometers. Magadzirirwo egirazi ekutengeserana akajairika haashande pano.
- Dhayamita uye Ukobvu: Mafomati akajairika anosanganisira mawafer e200mm ne300mm, ane ukobvu hunotangira pa0.3mm kusvika 5mm.
- Kushivirira Ukobvu: Tinoramba tichishivirira zvakasimba, kazhinji ±5µm, kuti tive nechokwadi chekuti wafer yese yakafanana.
- Kusiyana Kwehukobvu Hwose (TTV): TTV ye <5µm inokosha pakuchengetedza kutarisisa uye kudzivirira kushanduka-shanduka kwemaziso mumagungano e optical akaunganidzwa.
- Kusatsetseka: Kuti mufananidzo usakanganiswe, uta newarp zvinofanirwa kudzorwa kusvika <20µm uye <5µm zvakateerana.
Kupera Kwepamusoro uye Kuoma
Hunhu hwepamusoro pegirazi hunokanganisa zvakananga kufambiswa kwechiedza uye kupararira kwacho.
- Kuomarara (Ra): Kune zvikamu zve optical zveAR VR zvinoshanda zvakanyanya, tinowana kukosha kwekuomarara kwepamusoro kweRa <1nm. Kuomarara uku kunoderedza kupararira kwechiedza uye mhute, zvichiita kuti pave nekusiyana kwakanyanya uye kujeka.
- Hunhu Hwepamusoro: Tichitevedzera mwero weMIL-PRF-13830B, tinowanzopa magirazi ane chiyero che40-20 chekukwenya kana kupfuura. Mukushandiswa kunonyanya kukanganisa senge lithography kana laser optics, kunyangwe kukuvara kwepasi pevhu kunofanirwa kubviswa kuburikidza nehunyanzvi hwepamusoro hwekupukuta.
Kugadziriswa Kwepamusoro uye Kuputira
Girazi risina kubikwa ingori mavambo. Mashandiro ewafer anotsanangurwa nekugadzirwa kwayo.
- Kupukuta Mativi Maviri (DSP): Zvakakosha pamashandisirwo anoda kupenya kwemaziso kumativi ese, akadai semabeam splitters kana magirazi ekufukidza masisitimu eLiDAR.
- Mapendi Anodzivirira Kupenya (AR): Kuti chiedza chiwedzere kupenya (kazhinji >98%), mapendi eAR akanyatsogadzirwa anoiswa. Spectrophotometry inoshandiswa kusimbisa mashandiro ependi mu spectrum inoonekwa (400-700nm) kana mawavelengths chaiwo elaser (semuenzaniso, 940nm ye3D sensing).
- Kucheka neKuumba neLaser: Kune ma geometries akagadzirwa kana kuti ma optics asina kutenderera, kucheka nelaser kunoita kuti mipendero ive yakachena uye ine mitsetse midiki midiki, zvichideredza kudiwa kwekukuya mipendero yakawanda.

Metrology uye Kuvimbisa Hunhu
Kuti zvive nechokwadi chekuti zvinhu izvi zvinodiwa zvinoda metrology yemazuva ano. Tinoshandisa interferometry kuti tiongorore kuti zvinhu zvakati sandara uye TTV zvakati sandara sei pamusoro pewafer yese. Kuti tisimbise coating, ma spectrophotometer anoyera transmission uye reflection pamhando dzakasiyana dzezviitiko (AOI).
Ungave uri kugadzira mamodule e3D sensing emafoni kana mawaveguides akaomarara e diffractive eAR magirazi, mhando ye substrate yako ndiyo inotsanangura muganho wekushanda kwesystem yako.
Batana neZHHIMG
KuZHHIMG, isu tine hunyanzvi mukugadzira magirazi ekugadzira mawafer akakodzera anoenderana nezvinodiwa zvakanyanya neindasitiri yemaziso. Kubva pakusarudza zvinhu kusvika pakuputira kwekupedzisira, tinopa mhinduro dzinobva kumagumo dzinokubatsira kusundira miganhu yezvinogona kuitika muAR neVR.
