I. Core Functions: Ka Nģ'ane ho "Tšireletso"
Sekoaelo sa fensetere sa LiDAR ke thebe ea optical flat kapa spherical thebe e koahelang karolo e kantle ea sensor ea LiDAR. Mesebetsi ea eona ea bohlokoa e kenyelletsa:

1. Tšireletso ea 'Mele:E arola ka katleho lerōle, mongobo, oli, esita le lithōle tse fofang, e sireletsa likarolo tsa ka hare (mohlala, li-emitters tsa laser, li-detectors, liipone tse hlahlobang).
2. Tiiso ea Tikoloho:E le karolo ea matlo, e etsa tiiso e thibelang moea e nang le likarolo tsa moralo ho finyella litekanyetso tse hlokahalang tsa IP (mohlala, IP6K7/IP6K9K), ho netefatsa ts'ebetso e tsitsitseng maemong a thata joalo ka pula, lehloa le lifefo tsa lehlabathe.
3. Phetiso ea Optical:Mosebetsi oa eona oa bohlokoa ka ho fetisisa ke ho lumella li-lasers tsa maqhubu a khethehileng hore li fete ka mokhoa o atlehileng le ho khopama ho fokolang. Thibelo leha e le efe, ho thuisa, kapa ho kheloha ho fokotsa ka ho toba ho nepahala le boleng ba maru.

II. Lisebelisoa tse Ka sehloohong: Ntoa ea Likhalase.
Khetho ea thepa e laola siling ea ts'ebetso ea likoahelo tsa fensetere. Indasteri e kholo e sebelisa lisebelisoa tse entsoeng ka khalase, haholo-holo mefuta e 'meli:
1. Khalase ea silika e kopantsoeng

• Litšobotsi:Kakaretso ea mantlha bakeng sa lits'ebetso tsa likoloi le tsa indasteri. E entsoe ka silika e hloekileng haholo, e fana ka lisebelisoa tse ikhethang tsa optical.

• Melemo:

1. Phetisetso e ntle haholo ho tloha ho UV ho ea ho IR ka ho monya ho tlase haholo.
2. Mocheso o tlase oa ho eketsa mocheso o mamella mocheso o feteletseng (-60 ° C ho ea + 200 ° C) ntle le ho senyeha.
3. Boima bo phahameng (Mohs ~ 7), bo hananang le ho khoptjoa ke lehlabathe / moea.

• Lisebelisoa:Likoloi tse ikemetseng, li-AGV tsa indasteri tse phahameng, ho hlahloba LiDAR.

Fensetere ea mehato ea Sapphire

2. Khalase ea Sapphire

• Litšobotsi:Synthetic single-crystal α-alumina, e emelang ts'ebetso e phahameng haholo.

• Melemo:

1. Ho thatafala ho feteletseng (Mohs ~ 9, ea bobeli ka mor'a daemane), hoo e batlang e le bopaki ba ho ingoaea.
2. Transmittance optical e leka-lekaneng, ho hanyetsa mocheso o phahameng (ntlha ea ho qhibiliha ~ 2040 ° C), le botsitso ba lik'hemik'hale.

• Liqholotso:Litšenyehelo tse phahameng, ts'ebetso e thata (e hloka li-abrasives tsa daemane), le boima bo phahameng.
• .Lisebelisoa:Litekanyo tsa maemo a holimo tsa sesole, tsa sefofane le tse nepahetseng haholo.

III. Ho roala: Theknoloji ea Core e Fetolang Lejoe ho ba Khauta

Ho sa tsotelehe substrate, ho roala ho bohlokoa ho fihlela litlhoko tse thata tsa mahlo tsa LiDAR:

• .Anti-Reflection (AR) Coating:Lera bohlokoa ka ho fetisisa. E behiloe ka vacuum coating (mohlala, e-beam evaporation, magnetron sputtering), e fokotsa ponahalo ea bokaholimo ho <0.5% ho wavelengths e reriloeng, e matlafatsa phetisetso ho tloha ~ 92% ho isa> 99.5%.
• Ho roala ha Hydrophobic/Oleophobic:E thibela ho khomarela metsi / oli, ho boloka ho hlaka ha pula kapa libaka tse silafetseng.
• .Li-coatings tse ling tse sebetsang:Lifilimi tse futhumatsang tse senyang (tse sebelisang ITO), li-anti-static layers, joalo-joalo, bakeng sa litlhoko tse ikhethang.

IV. Lintlha tsa bohlokoa tsa ts'ebetso

Ha u khetha kapa u lekola sekoaelo sa fensetere sa LiDAR, tsepamisa maikutlo ho metrics ena:

1. Transmittance @ Target Wavelength:Peresente ea leseli le fetisoang ho leqhubu la tšebetso la LiDAR (mohlala,> 96% ho 905nm/1550nm post-AR coating).
2. Tšebelisano ea Band:E tlameha ho tsamaisana le maqhubu a laser (905nm/1550nm); ponahalo e lokela ho fokotsoa (<0.5%).
3. Ho Nepaha ha Sebopeho sa Bokaholimo:Liphoso tsa flatness le parallelism li lokela ho ba ≤λ/4 (λ = laser wavelength) ho qoba ho sotha ha mabala.
4. .Hardness & Wear Resistance:E lekantsoe ka sekala sa Mohs; bohlokoa bakeng sa ho tšoarella nako e telele.
5. Tikoloho Endurance:

• Ho hanyetsa metsi / lerole: Tekanyetso e tlase ea IP6K7.
• Mocheso oa ho palama baesekele: Sebaka sa ts'ebetso hangata -40°C ho ea +85°C.
• Ho hanyetsa ha mahlaseli a UV / letsoai ho thibela ho senyeha.

V. Maemo a Kopo

Hoo e ka bang lits'ebetso tsohle tsa LiDAR tse pepesitsoeng tikolohong li hloka sekoaelo sa lifensetere:

• Likoloi tse Ikemetseng:E lutse holim'a marulelo, li-bumpers, kapa mahlakoreng, e tobane le boemo ba leholimo le UV.
• Sistimi e tsoetseng pele ea Thuso ea Bakhanni (ADAS):E kopantsoe le 'mele oa likoloi, e hlokang tumellano ea botle.
• Liindasteri AGVs/AMRs:Ho sebetsa matlong a polokelo/ lifeme tse nang le lerole le likotsi tsa ho thulana.
• Boithuto le Boikutlo ba Remote:Litsamaiso tse tsamaeang ka moea / tsa koloi tse mamellang liphetoho tsa bophahamo le ho fetoha ha mocheso.
