Lub hauv paus ntsiab lus ua haujlwm thiab kev paub txog ntawm laser ntau yam finder
1. Lub hauv paus ntsiab lus ntawm kev siv infrared ntau yam lossis laser sib txawv
Lub hauv paus ntsiab lus ntawm qhov sib txawv tuaj yeem ua raws li ntsuas lub sijhawm xav tau rau lub teeb rov qab mus rau lub hom phiaj, thiab tom qab ntawd xam qhov deb D los ntawm qhov ceev ntawm lub teeb c=299792458m / s thiab atmospheric refraction coefficient n . Vim tias nws nyuaj rau ntsuas lub sijhawm ncaj qha, nws feem ntau yog ntsuas cov theem ntawm cov nthwv dej txuas ntxiv, uas yog hu ua theem ntsuas qhov ntsuas qhov ntsuas. Tau kawg, kuj tseem muaj cov mem tes rangefinders.
Nws yuav tsum raug sau tseg tias kev ntsuas theem tsis ntsuas theem ntawm infrared lossis laser, tab sis theem ntawm cov teeb liab hloov ntawm infrared lossis laser. Kev tsim kho kev lag luam muaj lub ntsuas hluav taws xob ntawm tes rau kev soj ntsuam hauv tsev uas ua haujlwm ntawm tib txoj cai.
2. Lub dav hlau ntawm cov khoom ntsuas yuav tsum yog perpendicular rau lub teeb
Feem ntau precision ntsuas qhov deb yuav tsum muaj kev koom tes ntawm tag nrho cov kev xav ntawm prism, thaum lub rangefinder siv rau kev ntsuas hauv tsev ncaj qha ntsuas nrog cov phab ntsa du, feem ntau vim qhov kev ncua deb kuj luv thiab lub teeb liab lub zog ntawm lub teeb pom kev rov qab yog qhov loj txaus. Nws tuaj yeem paub los ntawm qhov no tias nws yuav tsum yog ntsug, txwv tsis pub lub teeb liab rov qab tsis muaj zog dhau lawm thiab qhov tseeb nrug tsis tuaj yeem tau txais. Yog li qee zaum qhov yuam kev ntawm qhov rangefinder yuav tshwm sim los ntawm kev siv tsis raug ntawm qhov ntsuas.
3. Cov khoom dav hlau tuaj yeem ntsuas raws li diffuse reflection
Nws yog feem ntau ua tau. Nyob rau hauv qhov tseeb engineering, ib tug nyias yas phaj yog siv raws li ib tug reflective nto los daws qhov teeb meem ntawm loj diffuse reflection. Lub khw muag khoom lag luam CEM tab tom yuav cov khoom siv hluav taws xob, uas yuav muab pub dawb.
4. Cov khoom lag luam qib kev lom zem ntawm txoj kev pulse laser range finder tuaj yeem ua tiav qhov tseeb ntawm 1 meter, ntsuas qhov tseeb ntawm ± 1 meter, thiab cov khoom ntsuas ntsuas nrog qhov tseeb ntawm 0.1 meters thiab ntsuas qhov tseeb ntawm ±0.15 meters.
5. Qhov tseeb ntawm theem laser rangefinder tuaj yeem ncav cuag 1 hli yuam kev, uas yog tsim rau ntau yam kev ntsuas siab. Qhov tseeb ntawm CEM laser rangefinder yog ± 1.5MM, uas yog qhov tseeb tshaj plaws rangefinder ntawm lub khw.
