Dab tsi yog cov rangefinders ntau thiab kev faib tawm ntawm laser rangefinders hauv lub neej?
Laser ntau yam siv lub laser ua lub teeb ci rau ntau yam. Raws li txoj kev laser ua haujlwm, nws tuaj yeem muab faib ua cov laser txuas ntxiv thiab cov laser pulsed. Helium-neon, argon ion, krypton-cadmium thiab lwm yam roj lasers ua haujlwm hauv lub xeev cov zis tas mus li thiab siv rau theem laser ntau yam; ob chav heterogeneous gallium arsenide semiconductor lasers tuaj yeem siv rau ntau yam infrared; solid-state lasers xws li ruby thiab neodymium iav tuaj yeem siv rau hauv cov tshuab laser sib txawv.
Piv nrog rau photoelectric rangefinder, lub laser rangefinder tuaj yeem tsis tsuas yog ua haujlwm nruab hnub thiab hmo ntuj, tab sis kuj txhim kho qhov ntsuas qhov deb thiab txo qhov hnyav thiab lub zog noj, ua rau nws muaj tseeb los ntsuas qhov kev ncua deb ntawm lub hom phiaj xws li lub ntiaj teb dag satellites thiab lub hli. Yog hais tias lub laser yog emissions tsis tu ncua, qhov kev ntsuas yuav ncav cuag li 40 kilometers, thiab lub lag luam yuav nqa tawm ib hnub thiab hmo ntuj. Yog tias lub laser tawm hauv pulses, qhov tseeb qhov tseeb feem ntau yog tsawg, tab sis rau kev ntsuas qhov ntev, qhov tseeb txheeb ze tuaj yeem ua tiav.
Handheld Laser Rangefinder
Qhov ntsuas qhov deb yog feem ntau nyob rau hauv 200 meters, thiab qhov tseeb yog hais txog 2 hli. Qhov no yog tam sim no feem ntau siv laser range finder. Functionally, ntxiv rau ntsuas qhov kev ncua deb, nws tseem tuaj yeem xam qhov ntim ntawm cov khoom ntsuas.
Telescopic Laser Rangefinder
Qhov ntsuas qhov deb feem ntau yog li ntawm 600-3000 meters. Hom kab no muaj qhov ntsuas qhov ntev, tab sis qhov tseeb yog qhov tsawg, thiab qhov tseeb yog feem ntau txog 1 meter. Cov ntawv thov tseem ceeb yog kev ntsuas qhov ntev hauv thaj teb.
Muaj Laser Rangefinder
Qhov ntsuas qhov deb yog li ntawm 0.5-5000 meters, qhov tseeb yog nyob rau hauv 50mm, thiab ib tug reflector yuav tsum tau ntxiv 300 meters deb. Qee cov khoom tseem tuaj yeem ntsuas qhov nrawm thaum ntsuas qhov deb. Feem ntau yog siv los tswj txoj haujlwm, xws li tsheb thiab nkoj; positioning cranes; loading thiab unloading thiab tuav cov khoom; aircraft ntsuas, feem ntau yog ntsuas lub davhlau qhov siab; metallurgical txheej txheem tswj; ntsuas cov khoom siv tsis tau, xws li cov kav dej ntim, cov kav dej, cov thawv ntim khoom, thiab lwm yam, thiab ntsuas qhov ntsuas dej. Cov sensors yog LDM301, LDM4x.
