Dab tsi yog hom laser rangefinders?
1. Handheld laser range finder
Qhov ntsuas qhov deb yog feem ntau nyob rau hauv 200 meters, thiab qhov tseeb yog hais txog 2 hli. Qhov no yog ib tug laser rangefinder uas yog dav siv tam sim no. Ntxiv nrog rau kev ntsuas qhov deb, nws tseem tuaj yeem xam qhov ntim ntawm cov khoom ntsuas.
2. Huab kev pab cuam laser range finder
Cov ntaub ntawv ntsuas ntawm lub laser rangefinder tuaj yeem xa mus rau lub davhlau ya nyob twg xws li xov tooj ntawm tes thiab ntsiav tshuaj computers hauv lub sijhawm ntawm Bluetooth; cov ntaub ntawv tuaj yeem xa mus rau huab server los ntawm kev sib tham, thiab cov ntaub ntawv ntsuas tuaj yeem sib koom nrog cov neeg koom nrog kev tsim kho thaj chaw hauv lub sijhawm.
3. Telescope laser rangefinder
Kev ntsuas qhov deb yog qhov ntev, qhov ntsuas dav dav yog li 3.5 meters txog 2000 meters, thiab tseem muaj ntau yam-nrhiav telescopes nrog qhov siab tshaj plaws ntawm li 10 km. Raws li kev sib koom ua ke ntawm kev tshawb nrhiav lub koob yees duab, thaj chaw qhov muag tsis pom kev yog qis dua 3.5 meters, thiab qhov ntau yog ntau dua 2000 meters. Laser telescopes feem ntau siv YAG laser nrog lub wavelength ntawm 1.064 microns. Txhawm rau kom ua tiav qhov ntsuas qhov loj dua, lub zog laser yog qhov siab. Cov neeg siv tau qhia kom them sai sai rau kev tiv thaiv laser. Cov ntawv thov tseem ceeb yog qhov nruab nrab sab nraum zoov thiab ntsuas qhov ntev. Tsis tas li ntawd, nws kuj tseem tuaj yeem muab faib ua ib-dimensional laser range finder: rau kev ntsuas qhov deb thiab qhov chaw; ob-dimensional laser range finder: rau kev ntsuas contour, positioning, xyuas cheeb tsam thiab lwm yam teb; peb-dimensional laser range finder: rau peb-dimensional contour ntsuas, peb-dimensional chaw positioning thiab lwm yam teb.
