Cov yam ntxwv thiab kev faib tawm ntawm ntau yam finder
Lub laser range finder yog ib qho cuab yeej siv ib qho kev ntsuas ntawm lub laser modulated los ntsuas qhov deb ntawm lub hom phiaj. Lub pulsed laser rangefinder emits ib lub teeb los yog ib theem ntawm luv luv-lived pulsed laser beams rau lub hom phiaj thaum nws ua hauj lwm, thiab lub photoelectric caij tau txais lub laser beam reflected los ntawm lub hom phiaj. Lub timer ntsuas lub sij hawm los ntawm lub community launch mus rau lub txais tos ntawm lub laser beam, thiab xam qhov kev ncua deb ntawm lub 'meter' mus rau lub hom phiaj.
Yuav ua li cas Laser Rangefinders ua haujlwm
1. Lub hauv paus ntsiab lus ntawm kev siv infrared ntau yam lossis laser sib txawv
Lub hauv paus ntsiab lus ntawm kev sib txawv tuaj yeem ua raws li ntsuas lub sijhawm xav tau rau lub teeb kom rov qab mus rau lub hom phiaj, thiab tom qab ntawd xam qhov deb D los ntawm lub laser rangefinder 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, tseem muaj cov pulse range finders, feem ntau WILD's DI -3000.
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. Laser plummet tuaj yeem ntsuas cov khoom dav hlau 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.
3. 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 prism, thaum lub rangefinder thiab infrared tus pas ntsuas kub siv rau kev ntsuas hauv tsev ncaj qha 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.
4. Qhov tseeb ntawm ultrasonic ntau yam yog qhov tsawg, thiab nws tsis tshua siv.
5. Qhov tseeb ntawm lub laser rangefinder tuaj yeem ncav cuag qhov yuam kev 1 hli, uas yog tsim rau ntau yam kev ntsuas siab.
Nta ntawm Distance Meter:
Yooj yim: tsis xav tau cov reflectors, siv txhua lub sijhawm, nyob qhov twg, txawm tias huab cua phem
Hnab tshos: Me me thiab zoo heev, lub teeb thiab yooj yim nqa, tus neeg siv-phooj ywg tes tuav patented tsim
Kev Nyab Xeeb: Txais CLASS1 pob tshab laser uas tsis muaj teeb meem rau qhov muag
Flexible: Lub ntsuas ntsuas tuaj yeem hloov pauv ntawm "yard" thiab "meter" txhua lub sijhawm
High precision: qhov yuam kev siab tshaj plaws yog tsis ntau tshaj 1 meter
Los nag hom, nag yuav tsis cuam tshuam qhov ntsuas
>150m hom: Tsis tuaj yeem cuam tshuam los ntawm cov ntoo sib txawv nyob ze, nyob deb li deb
LCD zaub pom, cov ntaub ntawv xwm txheej yog meej ntawm ib nrais muag
Kev ua haujlwm ntsiag to, tsis siv neeg lub hwj chim tawm, roj teeb txheem
Built-in tripod standard interface
Kev ntsuas ntau: 10-1500 meters, qhov ntsuas qhov tsawg kawg nkaus yuav yog 10 yards,
Lub hom phiaj siab heev: 1500 meters (kwv yees 1642 yards)
General tsev: 1200 meters (kwv yees 1314 yards)
loj
Hom tsiaj: 600 meters (kwv yees 657 yards)
Luj: 420g (tsis muaj roj teeb)
Classification ntawm rangefinders
1. Handheld laser range finder
Qhov ntsuas qhov deb yog feem ntau nyob rau hauv 200 meters, thiab qhov tseeb yog hais txog 2 hli. Qhov no yog qhov feem ntau siv laser rangefinder tam sim no. Functionally, ntxiv rau ntsuas qhov kev ncua deb, nws kuj tseem tuaj yeem xam qhov ntim ntawm cov khoom ntsuas.
2. Huab kev pab cuam laser range finder
Cov ntaub ntawv ntsuas ntawm lub laser rangefinder raug xa mus rau cov khoom siv hluav taws xob xws li cov xov tooj ntawm tes thiab ntsiav tshuaj hauv lub sijhawm ntawm Bluetooth; cov ntaub ntawv tuaj yeem xa mus rau huab server los ntawm kev sib txuas wifi, thiab cov ntaub ntawv ntsuas tuaj yeem muab faib rau lub sijhawm tiag tiag nrog cov neeg siv khoom siv hauv thaj chaw deb.
3. Telescopic laser range finder
Qhov ntsuas qhov deb yog qhov ntev, thiab qhov ntsuas dav dav yog li 3.5 meters txog 2000 meters. Kuj tseem muaj ntau lub koob yees duab nrog qhov siab tshaj plaws ntawm 10 km. Raws li kev sib koom ua ke ntawm cov tsom iav tsom iav sib txawv, thaj chaw dig muag yog qis dua 3.5 meters, thiab lub laser ntau dua 2000 meters Telescopes feem ntau siv YAG lasers nrog lub wavelength ntawm 1.064 microns. Txhawm rau kom ua tiav qhov ntsuas qhov loj dua, lub zog laser yog qhov siab. Cov neeg siv tau qhia kom them sai sai rau kev tiv thaiv laser. Cov ntawv thov tseem ceeb yog qhov nruab nrab sab nraum zoov thiab ntsuas qhov ntev.
