Laser Distance Measuring Instrument Routine Maintenance
Laser rangefinders yuav tsum tau them sai sai rau kev siv qhov teeb meem: laser rangefinders tsis tuaj yeem tsom rau tib neeg qhov muag ncaj qha ntsuas, tiv thaiv kev puas tsuaj rau tib neeg lub cev. Nyob rau tib lub sijhawm, qhov dav dav laser rangefinder tsis muaj dej tsis muaj dej, yog li koj yuav tsum tau them sai sai rau cov dej tsis zoo. Qhov tseeb US Leo Porter laser rangefinder, vim hais tias hauv zos US feem ntau yog rau cov neeg yos hav zoov sab nraum zoov, yog li qhov zoo ntawm cov khoom ntawm qhov chaw tuaj yeem ua dej tsis zoo thiab tiv thaiv huab cua, nrog cov ntoo hav zoov ceg ntoo thiab nplooj pleev xim rau xim.
Laser tsis muaj kev ua haujlwm ntawm kev tiv thaiv poob, yog li lub laser rangefinder yog qhov yooj yim heev los tso cov khoom siv luminescent.
Laser rangefinder kho:
① feem ntau tshawb xyuas qhov zoo li ntawm cov cuab yeej raws sij hawm kom tshem tawm cov plua plav thiab av, roj, pwm thiab lwm yam.
② Ntxuav lub qhov muag, lub hom phiaj lo ntsiab muag lossis lub qhov rai laser emission yuav tsum siv cov ntaub mos muag. nruj me ntsis txwv tsis pub siv cov khoom siv tawv tawv khawb, thiaj li tsis ua rau cov khoom siv kho qhov muag puas.
③ Lub tshuab no yog optical, mechanical thiab hluav taws xob kev koom ua ke ntawm high-precision instruments, siv yuav tsum tau ua tib zoo thiab maj mam muab, yog nruj me ntsis txwv tsis pub extrusion los yog poob los ntawm qhov siab, thiaj li tsis mus ua puas lub ntsuas.
Functional yam ntxwv ntawm theem txoj kev rangefinder Taw qhia
Nyob rau hauv qhov muab modulation thiab cov qauv atmospheric tej yam kev mob, qhov zaus c/(4πf) yog ib tug tas mus li, nyob rau hauv lub sij hawm no qhov kev ntsuas ntawm qhov kev ncua deb dhau los ua qhov ntsuas ntawm tus naj npawb ntawm ib nrab- wavelengths uas muaj nyob rau hauv lub ntsuas kab thiab tsawg tshaj li ib nrab-wavelength ntawm lub Kev ntsuas ntawm qhov feem ntawm qhov ntsuas ntawm N los yog φ, vim yog kev txhim kho ntawm niaj hnub precision machining thev naus laus zis thiab xov tooj cua theem ntsuas tshuab, qhov ntsuas ntawm φ tau mus txog qib siab ntawm qhov tseeb.
Txhawm rau ntsuas lub kaum sab xis ntawm φ ntawm tsawg dua π, tuaj yeem ntsuas los ntawm ntau txoj kev, feem ntau yog siv ntau tshaj plaws yog qhov ncua sij hawm ntsuas thiab ntsuas theem digital, tam sim no luv-ntau laser rangefinder yog siv kom tau txais φ ntawm lub digital theem ntsuas txoj cai.
Los ntawm cov xwm txheej saum toj no hais txog theem hom laser xws li siv cov emissions txuas ntxiv ntawm cov kab teeb laser nrog cov teeb liab modulated, txhawm rau kom tau txais qhov tseeb ntau yam kuj yuav tsum tau teeb tsa lub hom phiaj kev koom tes, thiab tam sim no kev taw qhia ntawm handheld laser rangefinder yog lub mem tes laser rangefinder hauv lwm qhov. tshiab rangefinder, nws tsis yog tsuas yog me me, lub teeb yuag, tab sis kuj tseem siv cov digital phasing mem tes kis tau tus mob subdivision thev naus laus zis, tsis tas yuav koom tes nrog lub hom phiaj kom ua tiav millimeter-theem qhov raug, ntsuas ntau tshaj 100m, thiab tuaj yeem ceev ceev. thiab ua kom pom qhov deb ncaj qha.
