Txoj cai thiab daim ntawv thov ntawm Laser Range Finder
Laser range finders feem ntau siv ob txoj hauv kev los ntsuas qhov deb: pulse method thiab theem txheej txheem. Cov txheej txheem ntawm pulse txoj kev sib txawv yog raws li nram no: lub laser emitted los ntawm ntau yam finder yog reflected los ntawm cov khoom ntsuas thiab ces tau txais los ntawm cov range finder, thiab cov range finder sau lub sij hawm ntawm lub laser rov qab thiab tawm tib lub sij hawm. Ib nrab ntawm cov khoom ntawm qhov ceev ntawm lub teeb thiab lub sij hawm mus txawv tebchaws yog qhov kev ncua deb ntawm qhov rangefinder thiab cov khoom ntsuas. Qhov tseeb ntawm kev ntsuas qhov deb los ntawm txoj kev mem tes yog feem ntau nyob ib puag ncig ntxiv /- 1 meter. Tsis tas li ntawd, qhov ntsuas qhov muag tsis pom kev ntawm hom rangefinder feem ntau yog li 15 meters.
2. Dab tsi yog qhov tseem ceeb ntawm daim ntawv thov ntawm lub laser range finder?
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, railways, tiv thaiv kev ua phem / tub rog, kev ua liaj ua teb, hav zoov, vaj tsev, kev lom zem / kev ua si sab nraum zoov, thiab lwm yam..
3. 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 range finders, peb hu lawv "kev nyab xeeb". Rau 1064nm laser rangefinder, vim tias nws muaj peev xwm txaus ntshai rau tib neeg lub cev, peb hu nws "tsis muaj kev nyab xeeb".
