I. Imisebenzi enguNdoqo: Ngaphaya “koKhuseleko”
Isigqubuthelo sefestile ye-LiDAR sisikhuselo se-optical flat okanye i-spherical shield edibanisa inxalenye yangaphandle ye-sensor ye-LiDAR. Imisebenzi yayo ephambili ibandakanya:

1. Ukhuseleko loMzimba:Ukwahlula ngokufanelekileyo uthuli, ukufuma, ioyile, kunye nobutyobo obubhabhayo, ikhusela izinto zangaphakathi (umzekelo, ii-laser emitters, detectors, izibuko zokuskena).
2. Ukutywinwa kokusiNgqongileyo:Njengenxalenye yezindlu, yenza itywina elingangeni moya elinamalungu olwakhiwo ukuze kuphunyezwe iireyithingi ezifunekayo ze-IP (umzekelo, IP6K7/IP6K9K), ukuqinisekisa ukusebenza okuzinzileyo kwiimeko ezinzima njengemvula, ikhephu, kunye nesanti.
3. Ugqithiso lwe-Optical:Owona msebenzi ubaluleke kakhulu kukuvumela i-laser-wavelength ethile ukuba idlule ngokufanelekileyo kunye nokugqwetheka okuncinci. Nakuphi na ukuvaleka, ukubonakalisa, okanye ukuphambuka ngokuthe ngqo kunciphisa ukuchaneka okusukela kunye nomgangatho welifu.

II. Izinto ezingundoqo: Idabi leeglasi.
Ukukhetha izinto eziphathekayo kuchaza isilingi yokusebenza kweefestile zefestile. Ishishini eliphambili lisebenzisa izixhobo ezisekwe kwiglasi, ngokuyintloko iindidi ezimbini:
1. Iglasi yeSilica edibeneyo

• Iimpawu:Eyona nto ingundoqo kwizicelo zeemoto nezoshishino. Yenziwe nge-silica ecocekileyo, inika iipropathi ezikhethekileyo zamehlo.

• Izinto eziluncedo:

1. Ukuhanjiswa okugqwesileyo ukusuka kwi-UV ukuya kwi-IR kunye ne-ultra-low absorption.
2. I-coefficient yokwandisa i-thermal ephantsi imelana nokushisa okugqithisileyo (-60 ° C ukuya ku-200 ° C) ngaphandle kokuguqulwa.
3. Ukuqina okuphezulu (Mohs ~ 7), ukumelana nokukrazuka kwisanti/umoya.

• izicelo:Izithuthi ezizimelayo, ii-AGV zamashishini aphezulu, uphononongo lwe-LiDAR.

Ifestile yefestile yenyathelo leSapphire

2. Iglasi yeSapphire

• Iimpawu:Synthetic single-crystal α-alumina, emele ukusebenza ultra-high.

• Izinto eziluncedo:

1. Ukuqina okugqithisileyo (Mohs ~9, okwesibini kuphela kwidayimane), phantse ubungqina bokukrweleka.
2. Ukuhanjiswa kwe-Optical balanced, ukumelana nokushisa okuphezulu (i-melting point ~ 2040 ° C), kunye nokuzinza kweekhemikhali.

• Imingeni:Iindleko eziphezulu, ukucutshungulwa okunzima (kufuna i-diamond abrasives), kunye nokuxinana okuphezulu.
• .izicelo:Umkhosi ophakamileyo, i-aerospace, kunye nemilinganiselo ye-ultra-precision.

III. Ukwaleka: Itekhnoloji engundoqo eJika ilitye libe yiGolide

Nokuba yeyiphi na i-substrate, iingubo zibalulekile ukuhlangabezana neemfuno ezingqongqo ze-LiDAR:

• .I-Anti-Reflection (AR) Coating:Owona maleko ubaluleke kakhulu. Ifakwe nge-vacuum coating (umzekelo, i-e-beam evaporation, i-magnetron sputtering), inciphisa ukubonakala komphezulu ukuya ku-<0.5% kumaza ekujoliswe kuwo, ukonyusa ukuhanjiswa ukusuka kwi- ~ 92% ukuya kwi->99.5%.
• I-Hydrophobic/Oleophobic Coating:Ikhusela ukunamathela kwamanzi / ioli, ukugcina ukucaca kwimvula okanye indawo engcolileyo.
• .Ezinye iiCoatings ezisebenzayo:Iifilimu ezitshisayo ezitshabalalisayo (usebenzisa i-ITO), i-anti-static layers, njl., kwiimfuno ezikhethekileyo.

IV. IiParameters zokuSebenza eziphambili

Xa ukhetha okanye uvavanya ikhava yefestile ye-LiDAR, gxila kwezi metrics:

1. Ukuhanjiswa @ Ubude bobude obujoliswe kuko:Ipesenti yokukhanya okuhanjiswe kwi-wavelength yokusebenza ye-LiDAR (umzekelo,> 96% kwi-905nm / 1550nm ye-post-AR coating).
2. Ukuhambelana kwebhendi:Kufuneka ihambelane ne-laser wavelengths (905nm/1550nm); ukubonakalisa kufuneka kuncitshiswe (<0.5%).
3. Ukuchaneka komzobo ongaphezulu:Iimpazamo ze-Flatness kunye ne-parallelism kufuneka zibe ≤λ/4 (λ = laser wavelength) ukuphepha ukuphazamiseka kwe-beam.
4. .Ukuqina kunye noKunganyangeki:Ilinganiswe ngesikali se-Mohs; ibaluleke kakhulu kwisigxina sexesha elide.
5. Ukunyamezela kokusingqongileyo:

• Ukuchasana kwamanzi / nothuli: Ubuncinci bokulinganisa kwe-IP6K7.
• Ubushushu bebhayisikile: Uluhlu lokusebenza ngokuqhelekileyo -40°C ukuya +85°C.
• Ukumelana ne-UV / ityuwa yokutshiza ukukhusela ukuthotywa.

V. Iimeko zeSicelo

Phantse zonke iinkqubo ze-LiDAR ezivezwe ngokusingqongileyo zifuna izigqubuthelo zefestile:

• Izithuthi eziZimelayo:Ifakwe eluphahleni, iibhampa, okanye emacaleni, ijongene nokuvezwa ngokuthe ngqo kwimozulu kunye ne-UV.
• IiNkqubo zoNcedo loMqhubi oPhezulu (ADAS):Idityaniswe kwimizimba yezithuthi, efuna imvisiswano yobuhle.
• Ii-AGV/AMRs zamashishini:Ukusebenza kwiindawo zokugcina/kwimizi-mveliso enothuli kunye neengozi zokungqubana.
• UVavanyo kunye noVavanyo ukude:Iinkqubo zomoya/ ezixhonywe kwinqwelo-mafutha ezinyamezela utshintsho lobude kunye nokuguquguquka kobushushu.

Ukuqukumbela.

Nangona iyinto elula yomzimba, isigqubuthelo sefestile ye-LiDAR sibalulekile ekuqinisekiseni "umbono" ocacileyo nothembekileyo we-LiDAR. Uphuhliso lwayo luxhomekeke ekudityanisweni okunzulu kwesayensi yezinto, i-optics, iinkqubo zokugquma, kunye nobunjineli bokusingqongileyo. Njengoko ixesha leenkqubela phambili zokuqhuba ngokuzimeleyo, le “festile” iya kuqhubeka nokuvela, ikhusela umbono othe ngqo koomatshini.
