V. Mamiriro ekushandisa: Panorama kubva kuAutonomous Driving kuenda kuIndustrial Sensing

VI. Tekinoroji Evolution uye Remangwana Trends

Mune tekinoroji yemazuva ano yekunzwa, LiDAR (Kuona Chiedza uye Kupenya) inoita se "maziso" emuchina, kunyatsoona iyo 3D nyika nekuburitsa uye kugamuchira laser matanda. Aya "maziso" anoda pachena "lens inodzivirira" kuchengetedza - iyi ndiyo LiDAR Window Cover. Haisi chidimbu chegiraziwo zvadzo asi chikamu chehunyanzvi hwepamusoro-soro chinobatanidza sainzi yemidziyo, dhizaini yemaziso, uye mainjiniya chaiwo. Kuita kwayo kunotarisisa kurongeka kwekunzwa, huwandu, uye kuvimbika kwese kweLiDAR masisitimu.

I. Mabasa Anokosha: Kupfuura "Kudzivirira"
Iyo LiDAR hwindo chivharo ndeye optical flat kana spherical shield yakavharira iyo yekunze chikamu cheLiDAR sensor. Mabasa ayo akakosha anosanganisira:

1. Physical Protection:Zvinonyatso paradzanisa guruva, unyoro, mafuta, uye kunyange marara anobhururuka, kuchengetedza zvinhu zvemukati (semuenzaniso, laser emitters, detectors, scanning magirazi).
2. Environmental Chisimbiso:Sechikamu chedzimba, inoumba chisimbiso chisina mhepo chine zvimiro zvemukati kuti zviwane zvinodiwa IP ratings (semuenzaniso, IP6K7/IP6K9K), kuve nechokwadi chekushanda kwakagadzikana mumamiriro ezvinhu akaoma semvura, chando, uye madutu ejecha.
3. Optical Transmission:Basa rayo rinonyanya kukosha kubvumira chaiyo-wavelength lasers kuti ipfuure nemazvo nekukanganisa kushoma. Chero kuvharika, kufungidzira, kana aberration kunoderedza zvakananga kuenzana uye point Cloud quality.

II. Mainstream Materials: Hondo Yemagirazi.
Sarudzo yezvinhu inoraira sirin'i yekuita yevhavha yehwindo. Indasitiri mainstream inoshandisa girazi-based materials, kunyanya marudzi maviri:
1. Yakasanganiswa Silica Girazi

• Characteristics:Iwo absolute mainstream yemotokari uye maindasitiri application. Yakagadzirwa ne-high-purity silica, inopa yakasarudzika optical zvivakwa.

• Advantages:

1. Yakanakisa kutapurirana kubva kuUV kuenda kuIR ine Ultra-yakaderera absorption.
2. Kudzikira kwekuwedzera kwekushisa kunomira kutonhora kwakanyanya (-60 ° C kusvika +200 ° C) pasina deformation.
3. Kuomarara kwepamusoro (Mohs ~ 7), kunopesana nekuputika kubva kujecha / mhepo.

• Applications:Mota dzinozvimiririra, dzepamusoro-magumo maindasitiri AGVs, kuongorora LiDAR.

2. Sapphire Girazi

• Characteristics:Synthetic single-crystal α-alumina, inomiririra ultra-high performance.

• Advantages:

1. Kunyanya kuoma (Mohs ~ 9, yechipiri chete kune dhaimani), ingangoita kukwenya-chiratidzo.
2. Balanced optical transmittance, yakakwirira tembiricha kuramba (melting point ~ 2040 ° C), uye kugadzikana kwemakemikari.

• Matambudziko:Mutengo wakakwira, wakaoma kugadzirisa (zvinoda madhaimondi abrasives), uye yakakwira density.
• .Applications:Yepamusoro-yekupedzisira mauto, aerospace, uye ekupedzisira-chaiyo zviyero.

III. Kupfeka: Iyo Core Tekinoroji Inoshandura Dombo kuita Goridhe

Pasinei neiyo substrate, machira akakosha kusangana neLiDAR's stringent optical zvinodiwa:

• .Anti-Reflection (AR) Coating:Iyo yakanyanya kukosha layer. Deposited via vacuum coating (semuenzaniso, e-beam evaporation, magnetron sputtering), inoderedza kutarisika kwepasi kusvika ku <0.5% pachinangwa chewavelengths, inowedzera transmittance kubva ~ 92% kusvika> 99.5%.
• Hydrophobic/Oleophobic Coating:Inodzivirira kunamatira kwemvura / mafuta, kuchengetedza kujeka mumvura kana nharaunda dzakasvibiswa.
• .Zvimwe zvinoshanda Coatings:Mafirimu ekupisa anopisa (uchishandisa ITO), anti-static layers, nezvimwewo, kune zvakakosha zvinodiwa.

IV. Key Performance Parameters

Paunenge uchisarudza kana kuongorora LiDAR hwindo kavha, tarisa pane aya metrics:

1. Transmittance @ Target Wavelength:Chiyero chechiedza chinofambiswa paLiDAR's wavelength yekushanda (semuenzaniso,> 96% pa905nm/1550nm post-AR coating).
2. Band Kuenderana:Inofanirwa kuenzanisa laser wavelengths (905nm/1550nm); kuratidza kunofanirwa kudzikiswa (<0.5%).
3. Kururamisa Kwemufananidzo Wepamusoro:Kukanganisa uye kuenderana kunofanirwa kuve ≤λ/4 (λ = laser wavelength) kudzivirira kukanganiswa kwedanda.
4. .Hardness & Wear Resistance:Kuyerwa neMohs scale; yakakosha pakusimba kwenguva refu.
5. Environmental Endurance:

• Mvura/guruva kuramba: Minimum IP6K7 rating.
• Tembiricha kubhasikoro: Operational range kazhinji -40°C kusvika +85°C.
• UV / munyu pfapfaidzo kuramba kudzivirira kudzikira.

Mota-yakaiswa LiDAR

V. Application Scenarios

Anenge ese akafumurwa nharaunda LiDAR masisitimu anoda mahwindo anovhara:

• Autonomous Vehicles:Yakaiswa pamusoro pematenga edzimba, mabhampa, kana mativi, yakatarisana nekutarisana nemamiriro ekunze uye UV.
• Advanced Driver-Assistance Systems (ADAS):Yakabatanidzwa mumitumbi yemotokari, inoda kuwirirana kwakanaka.
• Industrial AGVs/AMRs:Kushanda mumatura/mafekitori ane huruva uye njodzi dzekudhumhana.
• Kuongorora uye Remote Sensing:Airborne / mota-yakaiswa masisitimu anotsungirira kukwira kwekuchinja uye tembiricha kuchinja.

Mhedziso.

Kunyangwe chiri nyore chikamu chemuviri, iyo LiDAR hwindo kavha yakakosha pakuona kwakajeka uye kwakavimbika "chiratidzo" cheLiDAR. Kubudirira kwayo kunoenderana nekubatanidzwa kwakadzama kwesainzi yezvinhu, optics, maitiro ekupfekedza, uye engineering yezvakatipoteredza. Sezvo nguva yekutyaira uchizvitonga ichifambira mberi, iyi "hwindo" icharamba ichishanduka, ichichengetedza maonero chaiwo emichina.
