I. Cov Haujlwm Tseem Ceeb: Tshaj Li "Kev Tiv Thaiv"
Lub qhov rais LiDAR yog ib daim ntaub thaiv uas muaj lub teeb tiaj tiaj los yog lub voj voog puag ncig uas npog sab nraud ntawm lub sensor LiDAR. Nws cov haujlwm tseem ceeb suav nrog:

1. Kev Tiv Thaiv Lub Cev:Tshem tawm cov hmoov av, cov dej noo, roj, thiab txawm tias cov khib nyiab ya, tiv thaiv cov khoom sab hauv (piv txwv li, cov tshuab laser, cov khoom ntes, cov iav scanning).
2. Kev Sib Txuas Ib puag ncig:Ua ib feem ntawm lub tsev, nws tsim cov foob airtight nrog cov khoom sib xyaw ua ke kom ua tiav qhov xav tau IP ratings (piv txwv li, IP6K7 / IP6K9K), kom ntseeg tau tias kev ua haujlwm ruaj khov hauv cov xwm txheej hnyav xws li nag, daus, thiab cua daj cua dub.
3. Kev xa xov optical:Nws lub luag haujlwm tseem ceeb tshaj plaws yog tso cai rau cov lasers tshwj xeeb-wavelength hla mus tau zoo nrog qhov tsis sib xws tsawg kawg nkaus. Txhua qhov kev thaiv, kev cuam tshuam, lossis kev hloov pauv ncaj qha txo qhov tseeb ntawm qhov ntau thiab qhov zoo ntawm cov ntsiab lus.

II. Cov Khoom Siv Tseem Ceeb: Kev Sib Ntaus ntawm Cov Iav​
Kev xaiv cov khoom siv ua rau lub qhov rais ua haujlwm tau zoo. Cov lag luam feem ntau siv cov khoom siv ua los ntawm iav, feem ntau yog ob hom:
1. Cov iav Silica sib xyaw

• Cov yam ntxwv:Qhov tseem ceeb tshaj plaws rau kev siv hauv tsheb thiab kev lag luam. Ua los ntawm cov silica ntshiab, nws muaj cov khoom siv kho qhov muag zoo heev.

• Qhov zoo:

1. Kev xa tawm zoo heev los ntawm UV mus rau IR nrog kev nqus dej tsawg heev.
2. Cov coefficient thermal expansion qis tuaj yeem tiv taus qhov kub thiab txias heev (-60 ° C txog + 200 ° C) yam tsis muaj kev hloov pauv.
3. Kev nyuaj siab (Mohs ~ 7), tiv taus kev puas tsuaj los ntawm xuab zeb / cua.

• Cov ntawv thov:Cov tsheb tsav tus kheej, cov AGVs kev lag luam siab heev, kev soj ntsuam LiDAR.

2. Sapphire iav

• Cov yam ntxwv:Cov khoom siv hluav taws xob ib leeg-siv lead ua α-alumina, sawv cev rau kev ua tau zoo heev.

• Qhov zoo:

1. Qhov nyuaj heev (Mohs ~ 9, thib ob tsuas yog pob zeb diamond), yuav luag tsis khawb.
2. Kev sib kis tau zoo ntawm lub teeb, kev tiv taus kub siab (melting point ~ 2040 ° C), thiab kev ruaj khov ntawm tshuaj lom neeg.

• Cov kev sib tw:Tus nqi siab, kev ua tiav nyuaj (yuav tsum tau siv cov pob zeb diamond abrasives), thiab qhov ceev ceev.
• ​Cov ntawv thov:Kev ntsuas tub rog siab heev, aerospace, thiab ultra-precision.

III. Txheej: Lub Tshuab Tseem Ceeb Uas Hloov Pob Zeb Mus Ua Kub

Txawm yog lub substrate twg los xij, cov coatings yog qhov tseem ceeb kom ua tau raws li LiDAR cov kev xav tau optical:

• ​Txheej Txheej Anti-Reflection (AR):Cov txheej tseem ceeb tshaj plaws. Tso rau ntawm lub tshuab nqus tsev (piv txwv li, e-beam evaporation, magnetron sputtering), nws txo qhov kev cuam tshuam ntawm qhov chaw mus rau <0.5% ntawm lub hom phiaj wavelengths, txhawb kev xa tawm ntawm ~ 92% mus rau > 99.5%.
• Txheej Hydrophobic / Oleophobic:Tiv thaiv kom tsis txhob muaj dej/roj lo rau, ua kom pom tseeb thaum los nag lossis muaj kuab paug.
• ​Lwm Cov Txheej Txheem Ua Haujlwm:Cov yeeb yaj kiab demisting cua sov (siv ITO), cov txheej tiv thaiv static, thiab lwm yam, rau cov kev xav tau tshwj xeeb.
