The principle of telescopic rangefinder and its key points of selection
Telescopic rangefinders usually use the pulse method to measure distance.The pulse method works as follows: the laser emitted by the rangefinder is reflected off the object to be measured, and is then received by the rangefinder, which simultaneously records the time of the laser round trip.Half the speed of light times the round trip time is the distance between the rangefinder and the object being measured.The accuracy of the pulse method used to measure the distance is usually about +/- 1 m.In addition, such rangefinders typically measure dead zones of about 15 meters.
Points of selection
1. The basic parameter of a telescopic rangefinder is to measure distance.First, you should choose a telescopic rangefinder that needs to measure distance.
2. Measurement accuracy. The nominal measurement accuracy of all manufacturers is +/- 1 meter, which is only theoretical data.The measurement accuracy depends on the target environment, telescope rangefinder lens, infrared laser emitter quality and data processor accuracy.
What are the parameters of laser rangefinder?
We must know the specifications and parameters of any type of product or product.Laser ranging sensors are no exception. The parameters that must be known when choosing laser ranging sensor are: measuring distance, measuring frequency and measuring accuracy.In addition to the use of the environment, measuring objects are also necessary parameters for laser selection.
Conventional lasers can measure 30 meters of naturally problematic surfaces, and reflectors should be set to 30 to 150 meters.However, the long-range laser rangefinder sensor measures distance (km).
