Keeb kwm ntawm handheld laser rangefinders
Lub laser rangefinder yog ib qho cuab yeej siv lub laser kom raug txiav txim siab qhov deb mus rau lub hom phiaj. Laser rangefinder nyob rau hauv kev ua hauj lwm mus rau lub hom phiaj tua ib tug zoo heev beam ntawm laser rangefinder lub teeb, los ntawm lub photoelectric Cheebtsam kom tau txais lub hom phiaj reflected laser beam, timer los txiav txim lub laser beam ntawm lub community launch kom tau txais lub sij hawm los xam qhov deb ntawm lub soj ntsuam rau lub hom phiaj. Yog tias lub laser tsis tu ncua, qhov ntau tuaj yeem ncav cuag li 40 km, fluorine-lined butterfly valve thiab tuaj yeem ua haujlwm nruab hnub thiab hmo ntuj. Yog tias lub laser yog pulsed, qhov tseeb qhov tseeb feem ntau yog qis, tab sis rau kev ntsuas qhov ntev, qhov tseeb txheeb ze tuaj yeem ua tiav. Lub ntiaj teb thawj laser, yog los ntawm Teb Chaws Asmeskas Hughes aircraft tuam txhab kws tshawb fawb Meiman hauv xyoo 1960, thawj zaug tsim tau zoo. Cov tub rog Asmeskas sai sai ntawm lub hauv paus no los ua kev tshawb fawb ntawm cov tub rog laser. 1961, thawj tub rog laser rangefinder los ntawm US tub rog ua qauv qhia, ntawm lub laser rangefinder sai sai tom qab ntawd mus rau hauv lub cev sib koom ua ke. Laser rangefinder lub teeb yuag, me me, yooj yim rau kev khiav lag luam ceev thiab raug, nws qhov kev ua yuam kev tsuas yog ib feem tsib mus rau ntau pua pua ntawm lwm qhov chaw kho qhov muag, thiab yog li siv dav hauv kev soj ntsuam struts, battlefield surveys, tanks, aircraft, ships thiab artillery ntawm lub hom phiaj ntawm kev ntsuas qhov deb, ntsuas huab cua, dav hlau, cuaj luaj, thiab qhov siab ntawm satellite thiab lwm yam. Nws yog ib qho tseem ceeb ntawm cov cuab yeej siv los txhim kho qhov tseeb ntawm cov tso tsheb hlau luam siab, dav hlau, nkoj thiab cov phom loj. Raws li tus nqi ntawm laser rangefinders tseem poob qis, kev lag luam tau maj mam pib siv laser rangefinders. Hauv tsev thiab txawv teb chaws, muaj ntau yam tshiab ntawm kev ntsuas kev ncua deb, me me, kev ua haujlwm ruaj khov thiab lwm yam zoo ntawm cov khoom me me rangefinder, tuaj yeem siv dav hauv kev ntsuas kev lag luam thiab kev tswj, mining, ports thiab lwm yam kev lag luam. Lub ntsiab kev faib tawm ntawm ib-dimensional laser rangefinder rau kev ntsuas deb, qhov chaw; ob-dimensional laser rangefinder (Scanning Laser Rangefinder) rau kev ntsuas contour, positioning, xyuas cheeb tsam thiab lwm yam teb; peb-dimensional laser rangefinder (3D Laser Rangefinder) rau peb-dimensional contour ntsuas, peb-dimensional spatial positioning thiab lwm qhov chaw.
