905nm Vs . 1535nm Laser Ranging Modules For UAV Applications

Laser Ranging ModulesNws yog ib qho tseem ceeb rau UAV lub peev xwm, ua kom muaj kev ua haujlwm zoo xws li kev zam kev cuam tshuam, struts nram qab no, 3D mapping, thiab lub hom phiaj tsim. Kev khiav hauj lwm wavelength ntawm LRF yog ib qho tseem ceeb parameter uas tswj nws kev cuam tshuam nrog huab cua, tib neeg lub qhov muag kev nyab xeeb, sensor technology, thiab system economics. Thaum 905nm modules tswj cov neeg siv khoom thiab kev lag luam teeb pom kev lag luam, 1535nm modules muaj nyob rau hauv siab -kawg tub rog thiab kev ua haujlwm.

1. Kev sib piv cov txuj ci tseem ceeb

1.1. Photonics & Atmospheric Propagation

905nm (Nyob ze -Infrared):Qhov no wavelength nyob rau hauv lub siab - cheeb tsam teb ntawm silicon-raws li photodetectors (xws li, APDs, PIN diodes), ua kom tsawg- nqi, tsim tau txais txiaj ntsig zoo heev. Txawm li cas los xij, nws luv luv wavelength ua rau nce Rayleigh thiab Mie tawg los ntawm atmospheric aerosols, dej tee, thiab hmoov av. Qhov no ua rau txo qis cov teeb liab lub zog hauv huab cua tsis zoo xws li huab cua, huab cua, lossis haze.

1535nm (luv luv -Wave Infrared - SWIR):Muab tso rau hauv qhov chaw "qhov rais kis tau tus mob," 1535nm muaj kev cuam tshuam qis dua thiab nqus los ntawm cov pa dej thiab cov aerosols. Qhov no ua rau muaj kev nkag tau zoo dua los ntawm qhov pom qhov tsis zoo (DVE). Cov cuab yeej ntsuas yuav tsum tau indium gallium arsenide (InGaAs) lossis lwm yam khoom siv hluav taws xob, uas yog kim dua thiab tej zaum yuav muaj suab nrov dua li silicon.

1.2. Kev txiav txim siab txog kev nyab xeeb Laser

905nm :ua.Qhov wavelength no yog tsom los ntawm lub cornea thiab lo ntsiab muag mus rau retina, tsim kom muaj lub zog loj ntawm qhov chaw me me. Txawm tias nruab nrab -lub zog hluav taws xob lasers tuaj yeem ua rau muaj kev pheej hmoo loj ntawm kev puas hlwb. Kev ua tiav qhov muag- kev ua raws li kev nyab xeeb (feem ntau nyob rau hauv IEC 60825-1 Chav Kawm 1) feem ntau yuav tsum muaj kev txwv lub zog, kev sib txawv ntawm lub nqaj nce, lossis kev tswj xyuas kev ua haujlwm nruj.

1535nm :ua.Muaj zog absorbed los ntawm ocular media (cornea thiab aqueous / vitreous lom zem) ua ntej mus txog lub retina. Cov cuab yeej tseem ceeb ntawm lub cev no tso cai rau kev txwv ntau dua qhov tso cai raug txwv (MPE). 1535nm tshuab tuaj yeem ua haujlwm ntawm lub zog tso zis ntau dua thaum tseem ua tiav Qib 1 qhov muag- ntawv pov thawj kev nyab xeeb, ua kom muaj kev ua tau zoo hauv qhov chaw tsis muaj kev txwv.

1.3. System Performance & Integration

Maximum Range & Accuracy:Rau qhov muab lub zog siab tshaj plaws laser, 1535nm modules feem ntau ua tiav ntau qhov kev ua haujlwm siab tshaj plaws, tshwj xeeb tshaj yog nyob rau hauv qhov tseeb, tsis yog - zoo tagnrho atmospheric tej yam kev mob. Ob lub wavelengths tuaj yeem ua tiav sub-meter mus rau centimeter- qib raug, nyob ntawm ntau lub sijhawm siv hluav taws xob thiab teeb liab ua ntau dua li ntawm wavelength nws tus kheej.

Covertness & Detectability:905nm hluav taws xob tuaj yeem kuaj pom los ntawm cov khoom siv silicon-raws li cov duab sensors (CCD/CMOS), muaj peev xwm nthuav tawm UAV lub xub ntiag. 1535nm pom tsis tau rau cov koob yees duab kev lag luam feem ntau thiab tib neeg lub qhov muag, muab cov txiaj ntsig zoo rau kev soj ntsuam thiab kev ua tub rog.

Qhov loj me, qhov hnyav, lub zog, thiab tus nqi (SWaP-C):905nm systems leverage mature, siab -Volume laser diode thiab detector manufacturing, ua rau compact, tsawg- zog, thiab nqi-zoo modules. 1535nm systems, feem ntau raws li fiber ntau los yog cov khoom-xeev lasers ua ke nrog InGaAs detectors, feem ntau loj dua, ntau dua, ntau dua, thiab ntau dua {6} nm.

2. Daim ntawv thov -Cov lus qhia tshwj xeeb

2.1. Txaus siab rau 905nm Module rau:

Consumer & Prosumer Drones:Tus nqi thiab qhov loj me yog thawj tus tsav tsheb. Cov ntawv thov suav nrog kev zam yam khoom yooj yim thiab siv ua si.

Kaw -Range Mapping & Inspection (<200m):Siab- daws teeb meem 3D qauv ntawm cov qauv, sab hauv tsev SLAM, thiab kev saib xyuas kev noj qab haus huv ntawm qoob loo hauv cov xwm txheej meej.

High-Frequency, Short-Ntau Yam Kev Tiv Thaiv:Qhov twg nrawm, ze- qhov ze ze yog xav tau rau kev ya davhlau nyob rau hauv qhov chaw paub, tswj tau.

Siab -Ntau, Tus Nqi-Sensitive Deployments:Xws li loj -scale precision ua liaj ua teb (txhaj tshuaj, noob) qhov twg units yog deployed nyob rau hauv fleets.

3. Kev tswj hwm & kev ua haujlwm cuam tshuam

Kev tswj hwm lub cev (piv txwv li, FAA, EASA) nce kev tshuaj xyuas UAV kev ua haujlwm, tshwj xeeb tshaj yog hais txog kev siv hluav taws xob laser. Kev xa tawm 905nm systems feem ntau xav tau cov ncauj lus kom ntxaws txog kev nyab xeeb, thaj chaw muaj kev phom sij, thiab kev txwv kev ua haujlwm . 1535nm systems, vim lawv cov kev faib ua kom muaj kev nyab xeeb dua, ua kom yooj yim rau kev ua raws cai thiab ua kom yooj yim rau kev npaj lub hom phiaj. Cov nqi khiav lag luam yuav tsum yog qhov tseem ceeb tsis yog tus nqi kho vajtse nkaus xwb tab sis kuj yog tus nqi ntawm kev ua raws cai, txo kev pheej hmoo, thiab kev txwv lub luag haujlwm.

4. Xaus & Yav Tom Ntej Outlook

Qhov kev xaiv ntawm 905nm thiab 1535nm LRF modules tsis yog tsuas yog cov txuj ci tab sis muaj tswv yim, cuam tshuam rau UAV lub hnab ntawv ua haujlwm, kev tswj hwm kev tswj hwm, thiab tus nqi ntawm lub neej.

xaiv 905nmrau missions prioritizingtus nqi qis, tsawg kawg SWaP, thiab siab -kev ua tau zoo nyob rau hauv meej, tswj, los yog luv luv - ib puag ncig.Nws tseem yog tus neeg ua haujlwm rau kev lag luam thiab kev lag luam kev lag luam uas cov xwm txheej tswj tau.

Xaiv 1535nmrau missions xav taukev ua tau zoo nyob rau hauv ib puag ncig nyuaj, qhov muag qhov muag -kev nyab xeeb rau kev siv tsis txwv, thiab siv tau ntev dua.Nws yog qhov kev xaiv meej rau kev tshaj lij, kev nyab xeeb- tseem ceeb, thiab kev tiv thaiv daim ntawv thov.

Lub neej yav tom ntej yuav pom kev sib koom ua ke, nrog rau kev nce qib hauv kev hloov kho qhov muag zaus thiab cov khoom siv semiconductor tshiab tuaj yeem txo tus nqi ntawm qhov muag - nyab xeeb, ntev - wavelength systems. Txawm li cas los xij, rau lub neej yav tom ntej, qhov dichotomy wavelength no yuav nyob twj ywm, coj los ntawm kev lag luam tseem ceeb - tawm ntawm kev lag luam ntawm silicon photonics thiab kev ua tau zoo / kev nyab xeeb zoo ntawm luv luv -wave infrared band. Cov kws tsim qauv tsim qauv yuav tsum nruj me ntsis ntsuas lawv qhov chaw ua haujlwm, kev pheej hmoo siab, thiab kev ua haujlwm tau zoo los ua qhov kev xaiv zoo.
