Explain the principle of telescope rangefinder and the key points of its selection

2021.12.31

principle

The pulse method is usually used to measure the distance of a telescope rangefinder. The process of the pulse method is as follows: the laser emitted by the rangefinder is reflected by the object to be measured, and then received by the rangefinder, and the laser round-trip time is recorded at the same time. Half of the product of the speed of light and the round-trip time is the distance between the rangefinder and the measured object. The accuracy of the pulse method used to measure distance is usually about +/- 1 meter. In addition, the measurement dead zone of the rangefinder is usually about 15 meters.

Pick point

1. The basic parameter of telescope rangefinder is measuring distance. First, you should select the telescope rangefinder that needs to measure the distance.

2. Measurement accuracy, all said measurement accuracy is +/-1 meter, this is only theoretical data. The measurement accuracy depends on the measurement target environment, the telescope ranging lens, the quality of the infrared laser transmitter and the accuracy of the data processor.
