How Accurate is a Laser Distance Meter?
Laser distance meters measure distances by taking lasers as the light source and can be roughly divided into CW laser distance meters and pulsed laser distance meters. Laser distance meters applying gases, including helium-neon, argon ions, and krypton cadmium, work with continuous output and are used for phase-shift laser ranging. Semi-conducting laser distance meters made of DH gallium arsenide are used for infrared distance ranging, while solid laser distance meters made of rubies and neodymium glass are used for pulsed laser ranging.
