Introduction of the laser range finder classification
The laser range finder is an instrument that uses a certain parameter of the modulated laser to accurately measure the distance of the target. The pulsed laser rangefinder emits a beam or a sequence of short-term pulsed laser beams to the target when it is working, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates The distance from the meter to the target.
Classification introduction of laser range finder
Laser rangefinders are divided into handheld laser rangefinders and telescopic laser rangefinders.
1. Handheld laser rangefinder: the measurement distance is generally within 200 meters, and the accuracy is about 2mm. This is the most widely used laser rangefinder at present. 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. There are also ranging telescopes with a maximum range of about 10 kilometers. Due to the collimation requirements of the ranging telescope, the range is less than 3.5 meters. It is a blind area. Laser telescopes over 2000 meters generally use YAG lasers with a wavelength of 1.064 microns. In order to achieve a larger measurement range, the laser power is relatively large. Users are advised to pay attention to laser protection. The main application range is outdoor medium and long distance measurement.
