Lub hauv paus ntsiab lus thiab cov yam ntxwv ntawm high-precision handheld telescopic laser rangefinder
High precision telescope handheld laser rangefinder khoom txoj cai:
Laser rangefinders feem ntau siv ob txoj hauv kev los ntsuas qhov kev ncua deb: pulse method thiab theem txheej txheem. Pulse method kev ntsuas qhov deb yog qhov no: rangefinder launched; laser los ntawm cov khoom ntsuas tom qab qhov kev xav thiab tom qab ntawd tau txais los ntawm rangefinder, rangefinder tib lub sijhawm los sau cov sijhawm mus ncig ntawm lub laser. 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 raug ntsuas. Qhov tseeb ntawm txoj kev mem tes ntawm kev ntsuas qhov deb yog feem ntau nyob ib ncig ntawm +/-1 meter. Tsis tas li ntawd, qhov ntsuas qhov muag tsis pom ntawm cov rangefinders feem ntau yog li ntawm 5-15 meters.
High precision telescope handheld laser rangefinder khoom nta:
Cov cuab yeej ua haujlwm nrog semiconductor laser ntawm 905 nm thiab 1540 nm. Rau 905 nm thiab 1540 nm laser rangefinder, peb hu nws "kev nyab xeeb". Kev ua haujlwm wavelength yog 1064 nm YAG laser. 1064 nm wavelength yog teeb meem rau tib neeg cov tawv nqaij thiab ob lub qhov muag, tshwj xeeb tshaj yog yog hais tias lub qhov muag yuam kev mus rau hauv kev sib cuag nrog 1064 nm wavelength laser, kev puas tsuaj rau lub qhov muag tej zaum yuav * poj niam txiv neej. Yog li ntawd, nyob rau hauv txawv teb chaws, handheld laser rangefinders, tag nrho outlawed 1064 nm laser. Hauv Suav teb, qee cov tuam txhab tseem tsim 1064 nm laser rangefinders. Raws li rau 1064nm laser rangefinders, peb hu lawv "tsis muaj kev nyab xeeb" vim tias lawv muaj peev xwm ua rau tib neeg lub cev.
