Lub koob yees duab laser rangefinder.
Qhov ntsuas qhov deb yog qhov ntev. Qhov kev ntsuas dav dav yog li 3.5 meters txog 2000 meters, thiab qhov siab tshaj plaws ntsuas qhov deb yog li 10 kilometers. Raws li kev ntsuas kev ncua deb, thaj chaw dig muag yog qis dua 3.5 meters, thiab qhov chaw dig muag qis dua 3.5 meters. Laser telescopes siab tshaj 2000 meters feem ntau siv YAG lasers. Lub wavelength yog 1.064 microns. Yuav kom ua tiav qhov kev ntsuas loj dua, lub zog laser loj dua.
