I. Core Functions: Tshaj "Kev Tiv Thaiv".
Lub LiDAR qhov rais npog yog ib qho kho qhov muag tiaj tus lossis lub ntsej muag kheej kheej encapsulating sab nraud ntawm LiDAR sensor. Nws cov haujlwm tseem ceeb suav nrog:

1. Kev tiv thaiv lub cev:Kev cais cov plua plav, noo noo, roj, thiab txawm tias ya cov khib nyiab, tiv thaiv cov khoom siv sab hauv (xws li laser emitters, detectors, scanning mirrors).
2. Environmental Sealing:Raws li ib feem ntawm cov vaj tsev, nws tsim ib qho airtight foob nrog cov qauv tsim kom ua tiav qhov kev ntsuam xyuas IP (xws li IP6K7 / IP6K9K), ua kom muaj kev ruaj ntseg hauv cov xwm txheej hnyav xws li los nag, daus, thiab cua daj cua dub.
3. Optical Transmission:Nws txoj haujlwm tseem ceeb tshaj plaws yog tso cai rau cov wavelength tshwj xeeb kom dhau los ntawm kev ua tau zoo nrog kev cuam tshuam tsawg. Txhua qhov thaiv, kev xav, lossis aberration ncaj qha txo qis qhov tseeb thiab taw tes huab zoo.

II. Mainstream Materials: Sib ntaus sib tua ntawm iavua
Cov khoom xaiv dictates qhov kev ua tau zoo qab nthab ntawm qhov rais npog. Kev lag luam mainstream siv cov khoom siv iav, feem ntau yog ob hom:
1. Fused Silica iav

• Yam ntxwv:Qhov tseem ceeb tshaj plaws rau kev siv tsheb thiab kev lag luam. Ua los ntawm high-purity silica, nws muaj cov khoom tshwj xeeb kho qhov muag.

• Qhov zoo:

1. Kev xa tawm zoo heev los ntawm UV mus rau IR nrog ultra-low absorption.
2. Tsawg thermal expansion coefficient withstands huab kub (-60 ° C rau + 200 ° C) yam tsis muaj deformation.
3. Siab hardness (Mohs ~ 7), resistant rau abrasion los ntawm xuab zeb / cua.

• Cov ntawv thov:Autonomous tsheb, high-end industrial AGVs, soj ntsuam LiDAR.

2. Sapphire iav

• Yam ntxwv:Synthetic ib leeg-crystal α-alumina, sawv cev rau kev ua haujlwm siab.

• Qhov zoo:

1. Hardness heev (Mohs ~ 9, thib ob tsuas yog pob zeb diamond), ze li khawb-pov thawj.
2. Kev sib npaug ntawm cov khoom siv kho qhov muag, qhov kub tsis kam (melting point ~ 2040 ° C), thiab tshuaj lom neeg ruaj khov.

• Cov kev sib tw:Tus nqi siab, kev ua haujlwm nyuaj (yuav tsum tau pob zeb diamond abrasives), thiab siab ceev.
• uaCov ntawv thov:High-end tub rog, aerospace, thiab ultra-precision ntsuas.

III. Txheej: Cov Txheej Txheem Txheej Txheem Uas Hloov Pob Zeb rau Kub

Txawm hais tias lub substrate, txheej txheej yog qhov tseem ceeb kom ua tau raws li LiDAR qhov kev xav tau kho qhov muag nruj:

• uaAnti-Reflection (AR) Txheej:Cov txheej txheem tseem ceeb tshaj plaws. Deposited ntawm lub tshuab nqus tsev txheej (xws li, e-nqaj evaporation, magnetron sputtering), nws txo qhov kev xav ntawm qhov chaw mus rau <0.5% ntawm lub hom phiaj wavelengths, boosting transmittance ntawm ~ 92% mus rau> 99.5%.
• Hydrophobic / Oleophobic Txheej:Tiv thaiv kom tsis txhob muaj dej / roj adhesion, tswj kom pom tseeb hauv cov nag lossis qhov chaw muaj kab mob.
• uaLwm Cov Txheej Txheem Txheej Txheem:Heated demisting films (siv ITO), anti-static txheej, thiab lwm yam, rau cov kev xav tau tshwj xeeb.

IV. Key Performance Parameters

Thaum xaiv lossis ntsuas LiDAR qhov rais npog, tsom mus rau cov kev ntsuas no:

1. Transmittance @ Lub Hom Phiaj Wavelength:Qhov feem pua ​​​​ntawm lub teeb xa tawm ntawm LiDAR qhov kev ua haujlwm wavelength (xws li,> 96% ntawm 905nm / 1550nm post-AR txheej).
2. Band Compatibility:Yuav tsum phim laser wavelength (905nm / 1550nm); Kev xav yuav tsum tau txo qis (<0.5%).
3. Surface Figure Accuracy:Flatness thiab parallelism yuam kev yuav tsum yog ≤λ / 4 (λ = laser wavelength) kom tsis txhob beam distortion.
4. uaHardness & Wear Resistance:Ntsuas los ntawm Mohs nplai; tseem ceeb rau lub sij hawm ntev durability.
5. Environmental Endurance:
