Taw qhia rau cov yam ntxwv ua haujlwm ntawm theem txoj kev rangefinder
Raws li muab kev hloov kho thiab cov txheej txheem atmospheric, qhov zaus c / (4 π f) yog qhov tas mus li, thiab qhov kev ntsuas ntawm qhov deb dhau los ua qhov ntsuas ntawm tus naj npawb ntawm ib nrab wavelengths suav nrog hauv kab ntsuas thiab ntsuas qhov feem ntau tsawg dua ib nrab wavelengths. , ie N los yog φ, Vim yog kev txhim kho ntawm niaj hnub precision machining tshuab thiab xov tooj cua theem ntsuas tshuab φ Qhov ntsuas tau ua tiav qhov tseeb.
Txhawm rau ntsuas lub kaum sab xis ntawm qis dua π φ, Cov txheej txheem sib txawv tuaj yeem siv rau kev ntsuas, thiab cov kev siv feem ntau yog ncua sij hawm ntsuas thiab ntsuas theem digital. Tam sim no, luv luv ntau laser rangefinders siv lub hauv paus ntsiab lus ntawm digital theem ntsuas kom tau txais φ.
Raws li tau hais los saum no, feem ntau, theem laser ntau yam siv lub teeb laser txuas ntxiv nrog cov teeb liab modulated. Txhawm rau kom ua tiav qhov tseeb ntau yam, cov hom phiaj sib koom tes yuav tsum tau teeb tsa. Tam sim no launched handheld laser rangefinder yog lwm hom tshiab rangefinder ntawm pulse laser rangefinders, uas tsis yog tsuas yog me me thiab lub teeb nyob rau hauv qhov hnyav, tab sis kuj siv digital theem ntsuas pulse broadning thiab subdivision technology. Yog tsis xav tau kev koom tes cov hom phiaj, millimeter qib qhov tseeb tuaj yeem ua tiav, thiab qhov ntsuas qhov ntsuas tau tshaj 100m, Thiab nws tuaj yeem ua tau sai thiab raug tso saib qhov kev ncua deb ncaj qha.
Kev ceev faj thaum siv lub laser rangefinder
Kev ceev faj thaum siv lub laser rangefinder: Lub laser rangefinder tsis tuaj yeem tsom ntawm tib neeg lub qhov muag rau kev ntsuas ncaj qha los tiv thaiv kev puas tsuaj rau tib neeg lub cev. Lub caij no, dav dav laser rangefinders tsis muaj dej tsis muaj dej, yog li nws yuav tsum tau them sai sai rau cov dej tsis zoo. Qhov tseeb American Leopold laser rangefinder yog qhov tsim nyog rau cov neeg nyiam yos hav zoov sab nraum zoov hauv Tebchaws Meskas, yog li qhov zoo ntawm nws cov khoom yog tias nws tuaj yeem ua dej tsis zoo thiab fogproof, thiab yog nruab nrog cov yeeb yuj hav zoov ntoo ceg thiab nplooj.
Lub laser tsis muaj kev ua haujlwm ntawm kev tiv thaiv kev poob, yog li lub laser rangefinder yog ib qho yooj yim rau kev puas tsuaj rau lub illuminator.
Laser rangefinder kho:
① Tsis tu ncua tshuaj xyuas qhov zoo li ntawm qhov ntsuas thiab tshem tawm cov plua plav, av, roj, pwm, thiab lwm yam.
② Thaum ntxuav lub qhov muag, lub hom phiaj, lossis lub qhov rais laser emission, yuav tsum siv daim ntaub mos muag. Nws yog nruj me ntsis txwv tsis pub khawb nrog cov khoom tawv kom tsis txhob ua rau kev ua haujlwm kho qhov muag.
③ Lub tshuab no yog cov cuab yeej ua haujlwm siab uas suav nrog optics, mechanics, thiab electronics. Nws yuav tsum tau ua tib zoo saib xyuas thaum siv thiab yog nruj me ntsis txwv tsis pub squeezing los yog ntog los ntawm qhov siab kom tsis txhob ua puas lub ntsuas.
