Classification of handheld laser rangefinders：
One-dimensional laser rangefinder is used for distance measurement and positioning;
Two-dimensional laser rangefinder (Scanning Laser Rangefinder) is used for contour measurement, positioning, area monitoring and other fields;
3D Laser Rangefinder is used in 3D contour measurement, 3D space positioning and other fields
Handheld laser rangefinder features:
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 tanks, aircraft, ships and artillery. As the price of laser rangefinders continues to drop, the industry has gradually begun to use laser rangefinders. A number of new miniature rangefinders have appeared at home and abroad with the advantages of fast ranging, small size and reliable performance, which can be widely used in industrial measurement and control, mines, ports and other fields.
