Laser rangefinder ntsuas ntau yam
Illumination ranging txoj kev tau muab faib ua theem hom rangefinders thiab pulse method rangefinders. Pulsed laser rangefinders emit ib lub teeb los yog ib tug series ntawm luv luv-lived pulsed laser beams mus rau lub hom phiaj thaum lub sij hawm ua hauj lwm, thiab lub photoelectric lub sij hawm tau txais lub laser reflected los ntawm lub hom phiaj. Lub timer ntsuas lub sij hawm los ntawm emission mus rau txais lub laser beam, thiab xam qhov kev ncua deb ntawm tus soj ntsuam mus rau lub hom phiaj. Cov txheej txheem theem laser rangefinder kuaj pom qhov deb los ntawm kev kuaj xyuas theem sib txawv ntawm lub teeb emitted thiab lub teeb pom kev thaum lawv nthuav tawm hauv qhov chaw. Lub laser rangefinder yog lub teeb hauv qhov hnyav, me me, yooj yim hauv kev ua haujlwm, nrawm thiab raug, thiab nws qhov kev ua yuam kev tsuas yog ib feem tsib mus rau ntau pua ntawm lwm cov khoom siv kho qhov muag. Daim duab ntawm sab xis yog cov txheej txheem theem rangefinder. thiab pulse method rangefinder diagram.
Dab tsi yog qhov yuam kev ntawm laser rangefinder?
Kev ntsuas qhov tseeb yog raws li ISO/R1938-1971 pom zoo los ntawm ISO, 95 feem pua cov txheeb cais ntseeg tau (2s, uas yog, ob npaug ntawm tus qauv sib txawv). Kev ntsuas qhov tseeb yog qhov kev ntsuas qhov yuam kev raws li qhov ntsuas ib puag ncig. Tsis muaj nyob rau hauv daim ntawv thov tshwj xeeb kev ua haujlwm thiab kev suav, xws li Pythagorean kev ntsuas thiab kev taug qab hom (kev ntsuas txuas mus ntxiv).
Muaj ob txoj hauv kev los siv lub laser rangefinder: txoj kev pulse thiab theem txoj kev.
Yog hais tias lub laser rangefinder siv pulse emission, qhov tseeb qhov tseeb feem ntau yog tsawg, tab sis rau kev ntsuas qhov ntev, nws tuaj yeem ua tiav qhov tseeb txheeb ze.
Yog hais tias lub laser rangefinder siv cov theem xeem, qhov tseeb tuaj yeem ncav cuag ntxiv lossis rho tawm 1 hli, uas yog qhov siab tshaj plaws hauv qhov rangefinder.
Qhov yuam kev ntawm qhov tseeb ntawm lub laser rangefinder tsis yog proportional rau qhov kev ncua deb ntsuas thiab yog tib yam li tag nrho cov nyob deb. Txawm li cas los xij, dhau qhov kev ncua deb yuav ua rau muaj qhov yuam kev los ntawm ntxiv /-5ppm (qhov ib lab) (ntxiv rau /-0.5mm/100m).
Qhov tseeb ntawm laser rangefinders yeej ib txwm muaj kev txhawj xeeb los ntawm cov neeg hauv kev lag luam, thiab cov khoom siv laser rangefinders yuav tsum muaj nyob rau hauv qee qhov kev lag luam. Rau nruab nrab thiab ntev-ntev telescope laser rangefinders, qhov tseeb ntawm qhov rangefinder no yog 1 mev ntxiv rau -1. Tam sim no, nws tuaj yeem raug hu ua high-precision laser rangefinder, nrog qhov tseeb ntawm 0.5 yards ntxiv rau -1. Qhov no high-precision rangefinder muaj qhov tseeb tsawg dua 0.5 yards hauv 100 meters.
Qhov yuam kev tseem ceeb ntawm rangefinder yog los ntawm kev ntsuas qhov yuam kev. Piv txwv li, lub teeb laser raug thaiv los yog nkag mus, qhov ntsuas qhov kawg taw tes raug xaiv tsis raug, thiab qhov rangefinder xaiv qhov ntsuas pib qhov tsis raug. Nyob rau hauv cov xwm txheej zoo, qhov yuam kev me me.
