Dab tsi yog qhov tseem ceeb ntawm daim ntawv thov ntawm laser rangefinders?
Laser rangefinders tau siv dav hauv cov haujlwm hauv qab no: hluav taws xob, kev txuag dej, kev sib txuas lus, ib puag ncig, kev tsim kho, geology, tub ceev xwm, kev tiv thaiv hluav taws, blasting, navigation, railway, tiv thaiv kev ua phem / tub rog, kev ua liaj ua teb, hav zoov, vaj tse, kev lom zem. / sab nraum zoov kev ua si, thiab lwm yam ..
Vim li cas thiaj muaj qhov sib txawv ntawm qhov hu ua "kev nyab xeeb" thiab "tsis zoo" laser range finders?
Raws li lub npe implies, lub laser range finder siv laser ua cov khoom tseem ceeb ua hauj lwm. Tam sim no, cov khoom siv ua haujlwm ntawm cov khoom siv ntawm tes laser ntau yam finder nyob rau hauv kev ua lag luam feem ntau muaj xws li cov hauv qab no: semiconductor lasers nrog ib tug ua hauj lwm wavelength ntawm 905 nm thiab 1540 nm, thiab YAG lasers nrog ib tug ua hauj lwm wavelength ntawm 1064 nm. Lub wavelength ntawm 1064 nanometers yog teeb meem rau tib neeg cov tawv nqaij thiab ob lub qhov muag, tshwj xeeb tshaj yog yog hais tias lub qhov muag raug yuam kev ntawm lub laser nrog ib tug wavelength ntawm 1064 nanometers, qhov kev puas tsuaj rau lub qhov muag tej zaum yuav mus tas li. Yog li ntawd, nyob rau hauv txawv teb chaws, lub 1064 nanometer laser yog kiag li txwv nyob rau hauv lub handheld laser rangefinder. Hauv Suav teb, qee cov tuam ntxhab kuj tsim 1064nm laser rangefinders.
Rau 905nm thiab 1540nm laser rangefinders, peb hu lawv "kev nyab xeeb". Rau 1064nm laser range finder, vim hais tias nws muaj peev xwm txaus ntshai rau tib neeg lub cev, peb hu nws "tsis muaj kev nyab xeeb".
