| Nqi | - Cov khoom pheej yig dua, cov khoom siv ntau dua. | - Ntau dua, siv cov khoom tshwj xeeb. |
| Qhov zoo tshaj plaws siv rau | - Cov ntawv thov raug nqi nrog cov kev xav tau nruab nrab. | - Kev siv high-end zoo li kev tsav tsheb tsis siv neeg xav tau ntev thiab kev nyab xeeb. |
Qhov kev sib piv ntawm 1550/1535nm thiab 905nm LiDAR systems qhia txog ntau qhov zoo ntawm kev siv lub tshuab ntev dua (1550/1535nm), tshwj xeeb tshaj yog hais txog kev nyab xeeb, ntau yam, thiab kev ua haujlwm hauv ntau yam ib puag ncig.Cov txiaj ntsig no ua rau 1550/1535nm LiDAR systems tshwj xeeb tshaj yog haum rau cov ntawv thov uas xav tau siab precision thiab kev ntseeg siab, xws li kev tsav tsheb.Nov yog cov ncauj lus kom ntxaws txog cov txiaj ntsig no:
1. Txhim kho qhov muag kev nyab xeeb
Qhov zoo tshaj plaws ntawm 1550/1535nm LiDAR systems yog lawv qhov kev nyab xeeb zoo dua rau tib neeg lub qhov muag.Qhov ntev wavelengths poob rau hauv ib pawg uas yog absorbed ntau npaum li cas los ntawm lub cornea thiab lens ntawm lub qhov muag, tiv thaiv lub teeb los mus txog rau rhiab retina.Cov yam ntxwv no tso cai rau cov tshuab no ua haujlwm ntawm qib siab zog thaum nyob hauv qhov txwv tsis pub muaj kev nyab xeeb, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau kev ua haujlwm siab LiDAR tsis muaj kev cuam tshuam rau tib neeg kev nyab xeeb.
2. Kev tshawb pom ntev dua
Ua tsaug rau lub peev xwm los tawm ntawm lub zog siab dua kom nyab xeeb, 1550/1535nm LiDAR systems tuaj yeem ua tiav qhov kev tshawb pom ntev dua.Qhov no yog qhov tseem ceeb rau cov tsheb uas tsis muaj zog, uas yuav tsum tau ntes cov khoom ntawm qhov deb kom txiav txim siab raws sijhawm.Qhov kev nthuav dav uas muab los ntawm cov wavelengths no ua kom muaj kev cia siab zoo dua thiab muaj peev xwm ua rau muaj peev xwm, txhim kho tag nrho kev nyab xeeb thiab kev ua tau zoo ntawm kev siv lub tshuab navigation.
3. Txhim kho kev ua tau zoo hauv huab cua tsis zoo
LiDAR cov tshuab ua haujlwm ntawm 1550/1535nm wavelengths qhia tau hais tias kev ua tau zoo dua hauv huab cua tsis zoo, xws li huab cua, nag, lossis plua plav.Cov wavelengths ntev no tuaj yeem nkag mus rau hauv cov huab cua zoo tshaj qhov luv wavelengths, tswj kev ua haujlwm thiab kev ntseeg siab thaum pom kev tsis zoo.Qhov kev muaj peev xwm no yog qhov tseem ceeb rau kev ua haujlwm zoo ib yam ntawm autonomous systems, tsis hais txog ib puag ncig.
4. Txo kev cuam tshuam los ntawm tshav ntuj thiab lwm yam teeb pom kev zoo
Lwm qhov zoo dua ntawm 1550/1535nm LiDAR yog nws qhov txo qis rau kev cuam tshuam los ntawm lub teeb ci, suav nrog hnub ci.Qhov tshwj xeeb wavelengths siv los ntawm cov tshuab no tsis tshua muaj nyob rau hauv tej yam ntuj tso thiab khoom siv teeb pom kev zoo, uas txo qhov kev pheej hmoo ntawm kev cuam tshuam uas tuaj yeem cuam tshuam qhov tseeb ntawm LiDAR's environmental mapping.Qhov no feature yog tshwj xeeb tshaj yog muaj txiaj ntsig nyob rau hauv cov xwm txheej uas qhov kev kuaj pom tseeb thiab daim ntawv qhia tseem ceeb heev.
5. Cov khoom nkag
Txawm hais tias tsis yog ib qho tseem ceeb rau txhua daim ntawv thov, qhov ntev wavelengths ntawm 1550/1535nm LiDAR systems tuaj yeem muab kev sib cuam tshuam me ntsis nrog qee cov ntaub ntawv, muaj peev xwm muab qhov zoo rau cov kev siv tshwj xeeb uas nkag mus rau lub teeb los ntawm cov khoom siv los yog qhov chaw (rau qee yam) tuaj yeem tau txais txiaj ntsig zoo. .
Txawm hais tias qhov zoo li no, kev xaiv ntawm 1550/1535nm thiab 905nm LiDAR systems kuj suav nrog kev txiav txim siab ntawm tus nqi thiab daim ntawv thov.Thaum 1550/1535nm systems muaj kev ua tau zoo thiab kev nyab xeeb, lawv feem ntau kim dua vim qhov nyuaj thiab qis qis ntawm lawv cov khoom.Yog li ntawd, kev txiav txim siab siv 1550/1535nm LiDAR tshuab feem ntau nyob ntawm cov kev xav tau tshwj xeeb ntawm daim ntawv thov, suav nrog ntau yam xav tau, kev xav txog kev nyab xeeb, ib puag ncig, thiab kev txwv nyiaj txiag.
