Kev faib tawm thiab ntsuas kev ua haujlwm ntawm laser rangefinders
Laser rangefinders tuaj yeem tso tawm ntau lub laser pulses los txiav txim seb ib yam khoom puas txav deb ntawm lossis mus txog lub teeb los ntawm Doppler effect. Vim qhov ceev ntawm lub teeb, qhov ntsuas no tsis raug nyob ze. Triangulation yog qhov tsim nyog dua thaum ntsuas qhov ntsuas qhov deb ntawm qhov ntsuas sub-millimeter.
Classification ntawm laser rangefinders
1. Handheld laser rangefinder: qhov ntsuas qhov deb feem ntau nyob hauv 200 meters, thiab qhov tseeb yog li 2 hli. Qhov no yog qhov feem ntau siv laser rangefinder tam sim no. Functionally, ntxiv rau ntsuas qhov kev ncua deb, nws tseem tuaj yeem xam qhov ntim ntawm cov khoom ntsuas.
2. Huab kev pab cuam laser rangefinder: xa cov ntaub ntawv ntsuas ntawm lub laser rangefinder mus rau cov terminals mobile xws li cov xov tooj ntawm tes thiab ntsiav tshuaj computers hauv lub sijhawm ntawm Bluetooth; los ntawm kev sib txuas ntawm wifi, cov ntaub ntawv tuaj yeem xa mus rau huab server, thiab cov neeg koom nrog kev tsim kho tej thaj chaw deb tuaj yeem qhia qhov ntsuas hauv cov ntaub ntawv sijhawm.
3. Telescope-type laser rangefinder: qhov ntsuas qhov deb kuj ntev, qhov kev ntsuas dav dav yog li 3.5 meters mus rau 2000 meters, thiab tseem muaj qhov ntsuas qhov ntsuas qhov ntsuas qhov siab tshaj plaws ntawm thaj tsam li 10 mais. Nws yog qhov muag tsis pom kev, thiab laser telescopes loj dua 2000 meters feem ntau siv
YAG laser muaj lub wavelength ntawm 1.064 microns. Txhawm rau kom ua tiav qhov ntsuas loj, lub zog laser yog qhov siab. Nws raug pom zoo tias cov neeg siv yuav tsum xyuam xim rau kev tiv thaiv laser.

Kev ceev faj rau kev yuav khoom laser range finder
1. Kev ntsuas ntau
2. Kev ntsuas qhov tseeb
3. Qhov twg siv
Hauv paus muab faib ua cov xwm txheej hauv qab no:
a) Nws tsuas yog yuav tsum ntsuas qhov kev ncua deb li ntawm ob peb meters lossis kaum ob meters,
Thiab thaum qhov tseeb qhov yuav tsum tau tsis siab. Cov lus qhia - "ultrasonic range finder" tuaj yeem xaiv.
Cov lus hais - Kev ntsuas cov txiaj ntsig ntawm ultrasonic rangefinder cuam tshuam zoo heev los ntawm ib puag ncig, thiab nws txoj kev ruaj ntseg thiab kev taw qhia yog qhov phem dua li ntawm lub laser rangefinder, tab sis tus nqi kuj pheej yig, thiab nws tsim nyog rau kev ntsuas sab hauv.
b) Kev ntsuas qhov deb tsis ntev, thiab nws feem ntau yog siv sab hauv tsev nrog cov kev xav tau siab.
Tswv yim - xaiv tau "Handheld Laser Rangefinder".
Lus Cim —— Lub handheld laser rangefinder yog qhov tsim nyog rau kev siv sab hauv tsev, thiab qhov ntsuas qhov tseeb thiab cov nyhuv zoo heev.
(Yog hais tias tus neeg siv yuav tsum tau ntes nyob rau hauv ib qho chaw sab nraum zoov, nws raug nquahu kom siv ib tug kws laser pom thiab lub reflector kom ua tau raws li qhov xav tau ntau yam thiab cov nyhuv.)
c) Qhov ntsuas qhov deb yog qhov ntev, thiab feem ntau yog siv rau sab nraum zoov.
