Ntau tus neeg yuav xav tias yog vim li cas laser rangefinder modules tuaj nyob rau hauv txawv wavelengths. Qhov tseeb yog, qhov sib txawv hauv wavelengths tshwm sim los sib npaug daim ntawv thov kev xav tau nrog cov kev txwv. Laser wavelength ncaj qha cuam tshuam rau kev ua haujlwm, kev nyab xeeb, thiab tus nqi. Nov yog cov lus piav qhia ntxaws txog cov laj thawj:
1. Qhov cuam tshuam ntawm wavelength ntawm lub cev yam ntxwv ntawm Rangefinding
(1) Atmospheric Attenuation thiab kis tau tus mob
Laser kis tau tus mob los ntawm atmospheric absorption thiab scattering, ob qho tib si ntawm cov wavelength heev-nyob ntawm seb.. Luv Wavelengths (piv txwv li, 532nm):experience ntau tseem ceeb tawg tawg (rayleigh scattering). Hauv qhov chaw muaj plua plav, pos huab, lossis nag los nag, kev poob qis yog qhov tseem ceeb, ua rau lawv tsis haum rau kev siv mus ntev. Mid-Range Wavelengths (piv txwv li, 808nm, 905nm):have tsawg atmospheric absorption thiab tawg, ua rau lawv cov kev xaiv tseem ceeb rau rangefinders, tshwj xeeb tshaj yog siv sab nraum zoov. Ntev Wavelengths (piv txwv li, 1535nm, 1550nm):srhiab heev rau cov dej vapor absorption nyob rau hauv tej yam kev mob tab sis muaj tsawg tawg thiab concentrated zog, haum rau ntev mus thiab tshwj xeeb ib puag ncig.
(2) Reflective yam ntxwv ntawm lub hom phiaj nto
Qhov cuam tshuam ntawm laser wavelengths ntawm lub hom phiaj ntawm qhov chaw cuam tshuam qhov kev tshawb nrhiav qhov ua tau zoo.
Luv luvwavelengthspua tau zoo nrog lub hom phiaj muaj kev cuam tshuam zoo heev tab sis muaj qhov cuam tshuam tsawg rau ntawm qhov tsaus ntuj lossis ntxhib. Nruab nrab-rnpau tawswavelengthsoffer zoo adaptability hla ntau yam ntaub ntawv thiab muaj nyob rau hauv rangefinding modules. Ntev Wavelengthsprovide zoo dua nkag mus rau ntawm qhov chaw ntxhib, ua rau lawv zoo tagnrho rau daim ntawv qhia struts thiab complex scenarios.
2. Qhov muag kev nyab xeeb thiab kev xaiv wavelength
Tib neeg lub qhov muag yog qhov nkag siab zoo rau pom lub teeb (400-700nm) thiab ze-infrared teeb (700-1000nm). Laser beams nyob rau hauv cov kab no tuaj yeem tsom mus rau retina thiab ua rau muaj kev puas tsuaj, yuav tsum muaj kev tswj hwm lub zog nruj thiab txwv kev siv cov xwm txheej thiab cov peev xwm tso tawm. NtevwAvelengths (piv txwv li, 1535nm, 1550nm)yog safer raws li lawv lub zog yog absorbed los ntawm lub cornea thiab lens, tiv thaiv ncaj qha raug rau lub retina. Qhov no txo qis kev pheej hmoo ntawm kev nyab xeeb, ua rau cov wavelengths muaj txiaj ntsig zoo rau kev ua tub rog thiab lub zog siab ntev-ntev rangefinding.
3. Technical Complexity thiab nqi
Qhov nyuaj thiab tus nqi ntawm laser rangefinder modules sib txawv heev nyob ntawm wavelength.
- 532nm (Green Lasers): Feem ntau tsim los ntawm zaus-doubling infrared lasers (1064nm). Cov txheej txheem no muaj kev ua haujlwm tsawg, siab kub dissipation yuav tsum, thiab cov nqi siab.
- 808nm, 905nm (Zoo-Infrared Lasers): Tau txais txiaj ntsig los ntawm cov tshuab semiconductor paub tab, muab kev ua haujlwm siab thiab tus nqi qis, ua rau lawv zoo tagnrho rau cov khoom siv qib siab.
- 1535nm, 1550nm (Fiber Lasers): Yuav tsum tau tshwj xeeb fiber ntau lasers thiab txuam detectors (xws li, InGaAs). Cov modules no kim dua tag nrho.
4. Daim ntawv thov xav tau hauv cov xwm txheej sib txawv
Rau short-dqhov tseebmkev yooj yim, 532nm thiab 905nm yog cov kev xaiv zoo heev. Txawm hais tias qhov cuam tshuam tawg yog qhov tseem ceeb ntawm qhov luv wavelength, lawv muaj kev cuam tshuam tsawg tshaj plaws ntawm qhov luv luv. Tsis tas li ntawd, 905nm lasers muab qhov sib npaug ntawm kev ua tau zoo thiab tus nqi, dhau los ua qhov kev xaiv tseem ceeb rau rangefinder modules.Rau long-dqhov tseebmeasurement: 1064nm thiab 1550nm wavelengths yog tsim nyog, raws li ntev wavelengths concentrate lub zog thiab nkag mus tau zoo dua, zoo tagnrho rau industrial thiab tub rog daim ntaub ntawv uas yuav tsum tau ntev-ntau thiab high-precision ntsuas.Rau high-lyog-ikev cuam tshuamenvironments, 1550nm wavelengths ua tau zoo nyob rau hauv cov xwm txheej zoo li no, vim tias lawv tsis tshua cuam tshuam los ntawm hnub ci cuam tshuam. Qhov no ua kom muaj lub teeb liab-rau-suab nrov piv nyob rau hauv lub teeb muaj zog, ua rau lawv haum rau sab nraum zoov radar thiab cov cuab yeej soj ntsuam.
Nrog rau qhov kev piav qhia no, tam sim no koj yuav tsum muaj kev nkag siab tob dua ntawm vim li cas laser rangefinder modules tuaj nyob rau hauv qhov sib txawv wavelengths. Yog tias koj muaj kev xav tau rau laser rangefinder modules lossis xav paub ntxiv, thov hu rau peb txhua lub sijhawm!
