The laser rangefinder uses a laser as a light source for distance
measurement. Can be divided into continuous laser and pulsed laser. Because the
laser has the characteristics of good monochromaticity and strong
directionality, coupled with the integration of electronic circuit
semiconductors, the laser rangefinder can not only work day and night, but also
improve the accuracy of ranging, significantly reduce weight and power
Hand-held laser rangefinder.
The measuring distance is generally within 200 meters, and the accuracy is about 2mm. This is currently the most widely used laser rangefinder. In addition to the energy measurement distance, the volume of the measurement object can generally be calculated.
Telescope laser rangefinder.
The measurement distance is generally about 600-3000 meters. This type of rangefinder measures a longer distance, but the accuracy is low, and the accuracy is generally about 1 meter. The main application range is long-distance measurement in the field.
Industrial laser rangefinder.
The measuring distance is about 0.5-3000 meters, and the accuracy is within 50mm. A reflector should be added to 300 meters away. Some products can measure the speed while measuring the distance. Mainly used for position control, such as vehicles and ships; positioning cranes; loading and unloading and handling equipment; aircraft measurement, mainly measuring flying height; metallurgical process control; measuring objects that should not be approached, such as pipeline filling, pipelines, containers, and water level measurement.
