Keeb kwm ntawm Handheld Laser Rangefinders
Lub laser rangefinder yog ib qho cuab yeej siv ib qho kev ntsuas ntawm lub laser modulated los ntsuas qhov kev ncua deb mus rau lub hom phiaj. Kev ntsuas ntau ntawm lub laser range finder yog 3.5 ~ 5000 meters.
Raws li txoj kev ntsuas qhov deb, nws tau muab faib ua cov txheej txheem theem finder thiab pulse method range finder. Lub pulse laser range finder emits ib tug nqaj lossis ib tug series ntawm luv luv mem tes laser beams rau lub hom phiaj thaum lub sij hawm ua hauj lwm, thiab lub photoelectric caij tau txais lub laser reflected los ntawm lub hom phiaj. Lub timer ntsuas lub sij hawm los ntawm kev xa mus rau kev txais tos ntawm lub laser beam, thiab xam qhov kev ncua deb ntawm tus neeg soj ntsuam mus rau lub hom phiaj. Cov theem txheej txheem laser rangefinder kuaj pom qhov deb los ntawm kev txheeb xyuas cov theem sib txawv ntawm lub teeb tawm thiab lub teeb pom kev thaum nws nthuav tawm hauv qhov chaw. Lub laser range finder yog lub teeb hauv qhov hnyav, me me, yooj yim rau kev khiav lag luam, ceev thiab raug, thiab nws qhov kev ua yuam kev tsuas yog ib feem tsib mus rau ntau pua ntawm lwm cov khoom siv kho qhov muag. Daim duab ntawm sab xis yog cov txheej txheem theem feem ntau nrhiav thiab pulse
Lub laser rangefinder yog ib qho cuab yeej siv laser los ntsuas qhov deb ntawm lub hom phiaj. Thaum lub laser rangefinder ua hauj lwm, nws emits ib tug nyias nyias laser beam rau lub hom phiaj. Lub photoelectric caij tau txais lub teeb pom kev zoo ntawm lub hom phiaj. Qhov kev ncua deb mus rau lub hom phiaj. Yog tias lub laser tawm tsis tu ncua, qhov ntsuas qhov ntev tuaj yeem ncav cuag li 40 km, thiab nws tuaj yeem ua haujlwm nruab hnub thiab hmo ntuj. Yog hais tias lub laser tawm hauv pulses, qhov tseeb qhov tseeb feem ntau yog tsawg, tab sis nws tuaj yeem ua tiav qhov tseeb txheeb ze thaum siv rau kev ntsuas kev deb. Lub ntiaj teb thawj lub laser tau ua tiav hauv xyoo 1960 los ntawm Maiman, tus kws tshawb fawb los ntawm Hughes Aircraft Company ntawm Tebchaws Meskas. Cov tub rog Asmeskas sai sai tau tshaj tawm kev tshawb fawb ntawm tub rog laser li ntawm lub hauv paus no. Xyoo 1961, thawj tub rog laser range finder dhau qhov kev sim ua qauv ntawm Asmeskas tub rog, tom qab ntawd lub laser range finder sai sai nkag mus rau qhov ua tau zoo. Lub laser range finder yog lub teeb hauv qhov hnyav, me me, yooj yim rau kev khiav lag luam, ceev thiab raug, thiab nws qhov kev ua yuam kev tsuas yog ib feem tsib mus rau ob peb pua ntawm lwm cov khoom siv kho qhov muag, yog li nws tau siv dav hauv kev ntsuas struts, kev ntsuas kev sib ntaus sib tua, tank, Aircraft, ships thiab artillery mus rau lub hom phiaj ntau, ntsuas qhov siab ntawm huab, aircraft, missiles thiab dag satellites, thiab lwm yam. Nws yog ib qho tseem ceeb cov cuab yeej cuab tam los txhim kho qhov tseeb ntawm siab tanks, aircraft, ships thiab artillery. Vim qhov txo qis ntawm tus nqi ntawm laser ntau yam finders, kev lag luam tau maj mam pib siv laser range finders. Hauv tsev thiab txawv teb chaws, ib pawg ntawm cov tshiab me me rangefinders nrog qhov zoo ntawm kev nrawm nrawm, me me thiab kev ua tau zoo tau tshwm sim, uas tuaj yeem siv dav hauv kev ntsuas kev lag luam thiab kev tswj hwm, mines, chaw nres nkoj thiab lwm qhov chaw. Kev faib tawm tseem ceeb Ib-dimensional laser rangefinder yog siv rau kev ntsuas qhov deb thiab qhov chaw; ob-dimensional laser rangefinder (Scanning Laser Rangefinder) yog siv rau kev ntsuas contour, qhov chaw, saib xyuas cheeb tsam thiab lwm yam; Peb-dimensional laser rangefinder (3D Laser Rangefinder) yog siv rau 3D profile ntsuas, 3D qhov chaw nyob thiab lwm yam.
