Advantages of lasers in Ranging
Laser is a non-contact industrial measurement technology that has the following advantages comparing with traditional contact ranging techniques:
- No need to get in physical touch in measuring surface, no deformation of the object that could lead to measurement errors
- No wear and tear will appear on the measurement surface due to physical touching while measuring.
- Laser measurement technology can be used in special environments where measurement with conventional tools is not possible.
The principle of laser ranging:
There are three main ranging methods: laser pulse ranging, laser phase ranging, laser triangulation ranging, etc. Different measuring methods correspond to different commonly used measuring ranges and accuracies.
laser pulse ranging is mainly used for long-distance ranging, measuring distances above the km level, with low accuracy, generally of the meter level;
Laser phase ranging is suitable for medium- and long-distance measuring, with commonly used measuring ranges including 50 m, 150 m
Laser triangulation is generally used for short distance (within 2 meters) and high accuracy measurement tasks, with a general accuracy of micron level, but the measurement distance is more limited.

Laser Rangefinder Module
Distance measurement modules:
A laser rangefinder is a device that measures the distance to a target by detecting the return signal of the emitted laser. The series of products are technically mature, stable, and can test a variety of static and dynamic targets, and can be equipped on a variety of platforms.
The Eye-safe Erbium-doped glass laser
The laser is positioned as an independent, controllable, domestically produced core device, with a combination of reliability and cost performance. The laser is produced by the laser’s own semiconductor pump source and the domestic advanced erbium glass crystal integration. The series of products have six product lines, and the first domestic orders have been completed, which can meet the annual production scale of tens of thousands of units in the future.
