Taw qhia rau kev faib cov laser rangefinders
Lub laser range finder yog ib qho cuab yeej siv ib qho kev ntsuas ntawm lub laser modulated los ntsuas qhov deb ntawm lub hom phiaj. Lub pulsed laser rangefinder emits ib lub teeb los yog ib ntus ntawm lub sij hawm luv luv pulsed laser beams rau lub hom phiaj thaum nws ua hauj lwm, thiab lub photoelectric caij tau txais lub laser beam reflected los ntawm lub hom phiaj. Lub timer ntsuas lub sij hawm los ntawm lub community launch mus rau lub txais tos ntawm lub laser beam, thiab xam qhov kev ncua deb ntawm lub 'meter' mus rau lub hom phiaj.
Classification qhia txog laser range finder
Laser rangefinders muab faib ua handheld laser rangefinders thiab telescopic laser rangefinders.
1. Handheld laser rangefinder: qhov ntsuas qhov deb feem ntau nyob hauv 200 meters, thiab qhov tseeb yog li 2 hli. Qhov no yog qhov feem ntau siv laser rangefinder tam sim no. Functionally, ntxiv rau ntsuas qhov kev ncua deb, nws tseem tuaj yeem xam qhov ntim ntawm cov khoom ntsuas.
2. Huab kev pab cuam laser rangefinder: xa cov ntaub ntawv ntsuas ntawm lub laser rangefinder mus rau cov terminals mobile xws li cov xov tooj ntawm tes thiab ntsiav tshuaj computers hauv lub sijhawm ntawm Bluetooth; los ntawm kev sib txuas ntawm wifi, cov ntaub ntawv tuaj yeem xa mus rau huab server, thiab kev ntsuas tuaj yeem sib koom nrog cov neeg koom nrog kev tsim kho tej thaj chaw deb hauv cov ntaub ntawv sijhawm.
3. Telescope-type laser rangefinder: qhov ntsuas qhov deb yog qhov ntev. Kev ntsuas dav dav yog li 3.5 meters txog 2000 meters. Kuj tseem muaj ntau lub koob yees duab nrog qhov siab tshaj plaws ntawm 10 km. Raws li qhov xav tau ntawm kev sib tsoo ntawm lub tsom iav raj, qhov ntau yog tsawg dua 3.5 meters. Nws yog thaj chaw dig muag. Laser telescopes tshaj 2000 meters feem ntau siv YAG lasers nrog lub wavelength ntawm 1.064 microns. Txhawm rau kom ua tiav qhov kev ntsuas loj dua, lub zog laser yog qhov loj. 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.
