Muaj ob peb yam koj yuav tsum xav txog thaum yuav lub laser rangefinder.
1. Kev npaj ntsuas.
2. Kev ntsuas qhov tseeb.
3. Qhov chaw siv.
Lub hauv paus tau muab faib ua cov xwm txheej hauv qab no:
a) Kev ntsuas qhov deb tsuas yog yuav tsum nyob rau hauv ob peb meters lossis kaum meters, thiab qhov yuav tsum tau ua kom raug tsis siab. Nws raug nquahu kom xaiv "Ultrasonic Range Finder" (cov ntsiab lus tam sim no tawm). Kev ntsuas cov nyhuv ntawm whitening-ultrasonic ntau yam finder yog heev cuam tshuam los ntawm ib puag ncig, thiab nws stability thiab directionality yog phem tshaj li ntawm laser range finder, tab sis tus nqi kuj pheej yig, thiab nws yog haum rau kev ntsuas sab hauv tsev.
b) Kev ntsuas qhov deb tsis ntev, thiab nws feem ntau yog siv sab hauv tsev nrog cov kev xav tau siab.
Ib qho "Handheld Laser Rangefinder" yog muaj rau kev yuav khoom. Filler - Lub handheld laser rangefinder yog tsim rau siv sab hauv tsev, thiab ntsuas qhov tseeb thiab cov nyhuv zoo heev. (Yog hais tias tus neeg siv yuav tsum tau ua kev tshawb fawb nyob rau hauv ib puag ncig sab nraum zoov, nws raug nquahu kom nruab ib lub laser pom thiab reflector, thiab siv nws ua ke kom ua tiav qhov kev xav tau thiab cov txiaj ntsig.
c) Qhov ntsuas qhov deb yog qhov ntev, thiab nws feem ntau yog siv hauv thaj chaw. Cov lus qhia - yuav ib lub "teescope laser rangefinder" (xws li laser rangefinder telescope)
Tam sim no raws li txoj cai thiab kev loj hlob tiam sis ntawm handheld laser rangefinders.
Qhov no yog lub sijhawm ntawm kev txhim kho thev naus laus zis sai, thiab tib neeg lub neej tau nce ntxiv ntawm kev siv thev naus laus zis. Siv lub laser rangefinder ua piv txwv. Yav dhau los, tib neeg siv daim kab xev ntsuas, off-line, ntsuas, thiab lwm yam los ntsuas qhov deb. Tam sim no cia li nias lub pob ntawm no me ntsis laser rangefinder thiab nws dhau lawm. Ntxiv mus, lub laser range finder muaj ntau dua precision thiab me me dua li ib txwm ntsuas txoj kev. Lub teeb nyhav thiab yooj yim nqa.
Vim muaj ntau yam kev siv, qhib lub laser rangefinders yog yooj yim. Tam sim no, laser range finders nyob rau hauv khw malls muaj xws li mem tes laser range finders thiab theem laser range finders. Thaum ob qho tib si siv los ntsuas qhov deb, lawv muaj lawv tus kheej cov txiaj ntsig. Nyob rau tib lub sijhawm, cov phiaj xwm ntsuas qhov tseeb ntawm cov mem tes laser range finder tsis zoo, thiab cov phiaj xwm ntsuas ntawm theem laser range finder yog me me, tab sis qhov tseeb yog siab, uas tuaj yeem ncav cuag mm qib. Daim ntawv thov teb ntawm pulsed laser range kuj tau dhau los ua ntau thiab ntau dua, xws li kev ntsuas topographical, tactical frontier range, missile orbit tracking, artificial satellites, kev ntsuas deb ntawm lub ntiaj teb mus rau lub hli, thiab lwm yam. Lub sijhawm luv laser mem tes, lub zog tseem ceeb, thiab lub zog siab sai. Nyob rau hauv cov ntaub ntawv ntawm kev koom tes txoj cai, pulsed laser ranging muaj peev xwm ua tau ib tug ntev heev ranges; Nws yog assumed tias tsuas yog lub me me reflection teeb liab tau los ntawm diffuse reflection ntawm lub pulsed laser siv txoj cai ntsuas yuav siv tau rau ntau yam. Yog li ntawd, cov txheej txheem pulsed laser range yog dav siv.
Tam sim no luv luv tham txog lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm pulse laser rangefinder: lub laser emitted los ntawm rangefinder tau txais los ntawm rangefinder tom qab tau xav txog los ntawm cov khoom ntsuas. Qhov ntau yam finder sau lub sij hawm reciprocating ntawm lub laser, ib nrab ntawm cov khoom ntawm qhov ceev ntawm lub teeb thiab lub sij hawm reciprocating yog qhov kev ncua deb ntawm qhov ntau finder thiab cov khoom ntsuas.
Kev ntsuas qhov tseeb ntawm cov mem tes laser rangefinder tsis zoo, thiab qhov tseeb dav dav tuaj yeem ncav cuag m. Yog li ntawd, nyob rau hauv qee qhov kev xav tau siab precision, qhov project yuav xav tau ib theem laser rangefinder. Txawm li cas los xij, vim qhov kev npaj ntsuas dav dav, qhov ntsuas qhov yuam kev ntawm ib lossis ob metres tam sim no siab heev.
