Technical classification of laser range finder
1. Handheld laser rangefinder: the measurement distance is generally within 200 meters, and the accuracy is about 2mm. This is currently the most widely used laser rangefinder. Functionally, in addition to measuring the distance, it can also generally calculate the volume of the measured object.
2. Cloud service laser rangefinder: transmit the measurement data on the laser rangefinder to mobile terminals such as mobile phones and tablet computers in real time through Bluetooth; through wifi networking, the data can be transmitted to the cloud server, and the measurement can be shared with remote construction partners in real time data.
3. Telescope-type laser rangefinder: the measurement distance is relatively long, the general measurement range is about 3.5 meters to 2000 meters, and there are also rangefinder telescopes with a maximum range of about 10 kilometers. It is a blind spot, and laser telescopes larger than 2000 meters generally use
YAG laser has a wavelength of 1.064 microns. In order to achieve a large measurement range, the laser power is relatively high. It is recommended that users pay attention to laser protection.
The main application range is outdoor medium and long distance measurement.
One-dimensional laser range finder
For distance measurement and positioning; laser range finder
Two-dimensional laser range finder (Scanning Laser Range finder)
Used in contour measurement, positioning, area monitoring and other fields;
3D Laser Range finder
It is used in three-dimensional contour measurement, three-dimensional space positioning and other fields.
