Ci ntsa iab rau yav tom ntej ntawm Kev Tshawb Nrhiav Chaw Nyob: Lumispot Tech's 1.5μm Pulsed Fiber Laser

Hauv kev ntsuas qhov tseeb thiab kev saib xyuas ib puag ncig, LiDAR thev naus laus zis sawv cev rau lub teeb ci ntsa iab uas tsis muaj lwm tus sib piv. Hauv nws lub hauv paus muaj ib qho tseem ceeb - lub hauv paus laser, uas yog lub luag haujlwm rau kev tso tawm cov teeb pom kev zoo uas ua rau ntsuas qhov deb tau zoo. Lumispot Tech, tus thawj coj hauv kev siv tshuab laser, tau tshaj tawm cov khoom hloov pauv kev ua si: 1.5μm pulsed fiber laser tsim rau LiDAR daim ntawv thov.

 

Ib qho kev pom rau hauv Pulsed Fiber Lasers

Lub laser fiber pulsed 1.5μm yog ib qho chaw tshwj xeeb uas tsim los kom tso tawm lub teeb luv luv thiab muaj zog ntawm qhov ntev ntawm kwv yees li 1.5 micrometers (μm). Nyob hauv qhov ze-infrared ntawm lub electromagnetic spectrum, qhov ntev tshwj xeeb no yog lub npe nrov rau nws qhov tso zis hluav taws xob siab tshaj plaws. Cov laser fiber pulsed tau pom ntau daim ntawv thov hauv kev sib txuas lus, kev kho mob, kev ua cov ntaub ntawv, thiab qhov tseem ceeb tshaj plaws, hauv LiDAR systems mob siab rau kev tshawb nrhiav chaw deb thiab kev kos duab.

 

Qhov Tseem Ceeb ntawm 1.5μm Wavelength hauv LiDAR Technology

Cov tshuab LiDAR siv cov laser pulses los ntsuas qhov deb thiab tsim cov duab 3D ntawm cov av lossis cov khoom. Kev xaiv ntawm qhov wavelength yog qhov tseem ceeb rau kev ua tau zoo tshaj plaws. Qhov wavelength 1.5μm ntaus qhov sib npaug ntawm kev nqus cua, kev tawg, thiab kev daws teeb meem ntau yam. Qhov chaw qab zib no hauv spectrum qhia txog kev nce qib zoo kawg nkaus hauv thaj chaw ntawm kev kos duab meej thiab kev saib xyuas ib puag ncig.

 

Lub Symphony ntawm Kev Koom Tes: Lumispot Tech thiab Hong Kong ASTRI

 

Kev koom tes ntawm Lumispot Tech thiab Hong Kong Applied Science and Technology Research Institute Co., Ltd. ua piv txwv txog lub zog ntawm kev koom tes hauv kev txhawb nqa kev nce qib ntawm thev naus laus zis. Los ntawm kev siv Lumispot Tech txoj kev txawj ntse hauv kev siv tshuab laser thiab lub koom haum tshawb fawb txoj kev nkag siab tob txog kev siv tau, lub tshuab laser no tau tsim los ua tib zoo kom ua tau raws li cov qauv ntawm kev lag luam mapping chaw taws teeb.

 

Kev Nyab Xeeb, Kev Ua Haujlwm Zoo, thiab Kev Ntsuas Tseeb: Lumispot Tech Lub Hom Phiaj

Hauv kev nrhiav kev ua tau zoo tshaj plaws, Lumispot Tech muab kev nyab xeeb, kev ua haujlwm zoo, thiab kev ua kom raug ua ntej ntawm nws lub tswv yim engineering. Nrog kev txhawj xeeb tseem ceeb rau kev nyab xeeb ntawm tib neeg lub qhov muag, lub laser no tau dhau los ntawm kev sim ua kom nruj kom ntseeg tau tias ua raws li cov qauv kev nyab xeeb thoob ntiaj teb.

 

Cov Nta Tseem Ceeb

 

Lub Zog Tso Tawm Siab Tshaj Plaws:Lub laser lub zog siab tshaj plaws ntawm 1.6kW (@ 1550nm, 3ns, 100kHz, 25 ℃) ua rau lub zog teeb liab zoo dua thiab nthuav dav ntau yam peev xwm, ua rau nws yog ib qho cuab yeej tseem ceeb rau LiDAR daim ntawv thov hauv ntau qhov chaw sib txawv.

 

Kev Hloov Pauv Hluav Taws Xob-Optical Siab:Kev ua kom muaj txiaj ntsig zoo tshaj plaws yog qhov tseem ceeb heev rau txhua qhov kev nce qib hauv kev siv tshuab. Lub laser fiber pulsed no muaj kev hloov pauv hluav taws xob zoo heev, txo qis kev siv hluav taws xob thiab xyuas kom meej tias feem ntau ntawm lub zog tau hloov mus ua cov zis pom kev zoo.

 

Qis ASE thiab Nonlinear Effect Noise:Kev ntsuas kom meej yuav tsum tau txo qhov suab nrov tsis xav tau. Lub laser no ua haujlwm nrog qhov tsawg kawg nkaus Amplified Spontaneous Emission (ASE) thiab suab nrov tsis sib xws, lav qhov huv thiab raug LiDAR cov ntaub ntawv.

 

Kev Ua Haujlwm Kub Dav Dav:Tsim los kom tiv taus ntau qhov kub thiab txias, nrog rau qhov kub ua haujlwm ntawm -40 ℃ txog 85 ℃ (@shell), qhov chaw laser no muab kev ua haujlwm zoo ib yam txawm tias nyob rau hauv qhov xwm txheej ib puag ncig uas xav tau tshaj plaws.
