Lub laser rangefinder yog ib qho cuab yeej siv lub laser los ntsuas qhov kev ncua deb mus rau lub hom phiaj. Lub laser rangefinder emits ib tug nyias nyias laser beam rau lub hom phiaj thaum nws ua hauj lwm, thiab lub laser beam reflected los ntawm lub hom phiaj yog tau txais los ntawm lub photoelectric caij.
Yog tias lub laser raug rho tawm haujlwm tas li, qhov ntsuas qhov ntev tuaj yeem ncav cuag li 40 km, thiab kev ua haujlwm 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 txheeb ze qhov tseeb tuaj yeem ua tiav.
Lub ntiaj teb' thawj laser yog thawj zaug tsim nyob rau hauv 1960 los ntawm American Hughes Aircraft Company tus kws tshawb fawb Maiman. Cov tub rog Asmeskas sai sai tau tshawb fawb txog cov tub rog laser li ntawm lub hauv paus no. Xyoo 1961, thawj tub rog laser rangefinder dhau qhov kev sim ua qauv ntawm Asmeskas cov tub rog, tom qab ntawd lub laser rangefinder sai sai nkag mus rau hauv cov koom haum ua haujlwm.
The laser rangefinder is light in weight, small in size, simple in operation, fast and accurate, and its error is only one-fifth to several hundredths of other optical rangefinders, so it is widely used in terrain measurement, battlefield measurement, tanks , ranging from aircraft, ships and artillery to targets, measuring the height of clouds, aircraft, missiles and artificial satellites, etc. It is an important technical equipment to improve the accuracy of high tanks, aircraft, ships and artillery.
Raws li tus nqi ntawm laser rangefinders tseem poob qis, kev lag luam tau maj mam pib siv laser rangefinders. Ib tug xov tooj ntawm cov tshiab miniature rangefinders tau tshwm sim hauv tsev thiab txawv teb chaws nrog qhov zoo ntawm kev nrawm nrawm, me me thiab kev ua tau zoo, uas tuaj yeem siv dav hauv kev ntsuas kev lag luam thiab kev tswj hwm, mines, chaw nres nkoj thiab lwm yam haujlwm.
