Brief Analysis: Laser Range Finder

2019-08-13
JRT laser ranging module has the following characteristics:

1. Long detection distance;

2. High ranging accuracy;

3. Strong anti-interference;

4. High cost performance ratio;

5. Small size;

6. Light weight.

Ranging method classification:

Pulse Ranging Method:

The range finder emits light pulses, which are reflected by the measured target, and then returns to the receiving system of the range finder to measure its transmission and reception.

The time interval of the optical pulse, i.e. the time t of the optical pulse to and fro at the distance to be measured, is mostly in the order of meters.

Phase Ranging Method:

By measuring the phase change of the continuous modulated light wave propagating to and fro over the distance to be measured, the indirect measurement time t is obtained.

This method has high measurement accuracy, so it has been widely used in engineering measurement.
