Tig atop autonomous tsheb, scanning ntsiag to hla hav zoov loj, txawm tias daim ntawv qhia struts ntawm qhov chaw nyob deb ntawm lub ntiaj teb -tom qab cov kev txiav no - Ntug thev naus laus zis scenes, ib qho tseem ceeb feem ntau yog ua hauj lwm: 1550nm wavelength LiDAR (Light Detection and Ranging). Piv nrog rau 905nm LiDAR yav dhau los, 1550nm LiDAR tau dhau los ua "qhov muag nyab xeeb" uas tho qhov pos huab ntawm lub neej yav tom ntej, qhib qhov ntev tshiab ntawm daim ntawv thov thoob plaws ntau qhov chaw tseem ceeb ua tsaug rau nws qhov tshwj xeeb zoo.
Technical Advantages: Kev nyab xeeb, rhiab heev, thiab nkag mus
Cov txiaj ntsig tseem ceeb ntawm 1550nm LiDAR qia ua ntej los ntawm nws "qhov muag- nyab xeeb" yam ntxwv. Qhov no wavelength nyob rau hauv ib tug "optical qhov rais" qhov twg tib neeg lub qhov muag muaj tsawg nqus, cia lub system siv mem tes zog theem kaum ntawm lub sij hawm siab tshaj cov 905nm lasers tsis muaj kev pheej hmoo ntawm retinal puas. Qhov no tsis tsuas yog txhim kho kev nyab xeeb tab sis txhais ncaj qha mus rau qhov kev tshawb pom ntau ntxiv (nce txog 200 meters, txawm tias ob peb mais) thiab siab dua thiab qhov tseeb ntawm cov ntaub ntawv huab cua.
Qhov thib ob, 1550nm band nyob rau hauv "kwj" ntawm hnub ci keeb kwm yav dhau los thiab muaj kev nkag mus rau huab cua zoo dua. Qhov no ua rau muaj kev ua tau zoo tshaj li 905nm lasers, tshwj xeeb tshaj yog nyob rau hauv huab cua phem xws li huab cua, haze, thiab lub teeb los nag. Tsis tas li ntawd, photodetectors rau cov qhab no (xws li indium gallium arsenide detectors) muaj suab nrov tsis tshua muaj suab nrov, zoo heev txhim kho lub teeb liab - rau - suab nrov piv thiab kev tshawb pom rhiab heev.
Core Application Scenarios
Siab -Level Autonomous Tsav Tsheb thiab Kev Tsav Tsheb Txawj Ntse: Qhov no yog qhov tseem ceeb tshaj plaws rau 1550nm LiDAR. Nws ultra- ntev nrhiav tau ntau yam thiab siab precision muab cov tsheb mus los ntawm kev kub ceev nrog lub sij hawm ntev cov tshuaj tiv thaiv, ua kom paub tseeb ntawm cov teeb meem me me nyob deb, txoj hauv kev, thiab cov cim kab. Nws muaj zog tiv thaiv kev cuam tshuam thiab kev ruaj ntseg hauv huab cua tsis zoo yog qhov tseem ceeb rau kev ua tiav kev nkag siab zoo rau L4 / L5 autonomy. Hauv tsheb-cov kev koom tes hauv kev koom tes hauv kev sib koom ua ke, txoj kev LiDAR kuj tseem tuaj yeem siv 1550nm thev naus laus zis rau holistic, dav - cheeb tsam kev nkag siab ntawm kev khiav tsheb.
Geographic Mapping thiab Resource Exploration: Hauv kev soj ntsuam hauv huab cua los yog qhov chaw hauv ntiaj teb, 1550nm LiDAR tuaj yeem nkag mus rau cov nroj tsuag me me kom tau txais cov qauv kev nce siab hauv av kom raug, siv rau cov duab kos duab, cov khoom siv hauv hav zoov, kev tshuaj xyuas kab hluav taws xob, thiab kev tshawb pom archaeological. Nws qhov ntev - muaj peev xwm ntau kuj ua rau nws yog ib qho cuab yeej zoo tshaj plaws rau loj -scale 3D lub nroog qauv.
Kev Tshawb Fawb thiab Kev Ruaj Ntseg: Hauv cov cheeb tsam uas xav tau qhov dav - cheeb tsam saib xyuas xws li cov chaw nres nkoj loj, mines, thiab ciam teb perimeters, 1550nm LiDAR tuaj yeem tsim kom muaj siab-paj nrig perimeter intrusion detection systems, enabling 24/7, tag nrho - huab cua taug qab thiab 预警 ntawm kev txav lub hom phiaj. Hauv kev lag luam automation, nws tuaj yeem siv rau ultra-ntev-ntau yam khoom ntim ntsuas thiab deformation xyuas ntawm cov qauv loj (xws li, cua turbine hniav).
Tshwj xeeb thiab Kev Tshawb Fawb Kev Tshawb Fawb: Nyob rau hauv daim ntawv thov nrog huab xav tau kev ntseeg siab thiab ntau yam, xws li UAV obstacle kev zam, robotic navigation, thiab kev tshawb nrhiav chaw (xws li, planetary landing guidance), 1550nm LiDAR muab ib tug irreplaceable tshuaj.
Kev sib tw thiab yav tom ntej Outlook
Txawm hais tias nws cov txiaj ntsig tseem ceeb, kev siv dav dav ntawm 1550nm LiDAR ntsib cov teeb meem. Nws cov khoom tseem ceeb -fiber lasers thiab InGaAs detectors- yog tus nqi ntau dua li cov semiconductor lasers thiab silicon detectors siv nyob rau hauv 905nm kev daws teeb meem, thiab kev sib koom ua ke yog ntau dua. Txawm li cas los xij, cov nqi tau poob sai heev ua tsaug rau cov thev naus laus zis, kev txhim kho cov saw hlau, thiab kev thawb rau tsheb- qib ntau lawm.
Saib tom ntej, 1550nm LiDAR modules yuav hloov mus rau kev ua tau zoo dua (xws li, kev daws teeb meem nce ntxiv, tus nqi ncej), cov qauv me me, tus nqi qis dua, thiab kev txawj ntse ntau dua (kho rau pem hauv ntej-kawg ua algorithms). Lawv sib sib zog nqus fusion nrog cov koob yees duab thiab millimeter -wave radar yuav dhau los ua tus qauv tsim rau kev tsim kom muaj kev nkag siab zoo.
Los ntawm kev ua kom muaj peev xwm siv tau ntawm cov tsheb uas muaj kev ywj pheej los txhawb kev tsim kho cov menyuam ntxaib digital thiab lub ntiaj teb ntse dua, 1550nm LiDAR, nrog rau nws qhov tshwj xeeb "lub zeem muag," yog qhib lub ntiaj teb uas peb tuaj yeem pom nyob deb dua, meej dua, thiab muaj kev nyab xeeb dua. Nws tsis yog ib yam khoom ntawm kev siv thev naus laus zis nkaus xwb tab sis yog qhov tseem ceeb ntawm kev qhib cov ntawv thov uas xav tau siab - kev ntseeg siab, ntev - ntau yam, thiab kev nkag siab meej.
