Review of 5 types of the best laser rangefinders

Laser rangefinder is a technological device for determining the distance by means of a laser beam. Models are divided into pulse and phase.

Principle of operation

Pulse . The principle of operation is based on the constant value of the speed of light. Knowing the travel time, the distance to the desired object is calculated. The luminous flux is supplied in short pulses.

They have high power, are used to measure large distances – from a kilometer to cosmic scales.

Phase . The work is based on the property of the light flux to change the modulation phase (in simplified terms, the oscillation parameters) when reflected from an object. The distance is calculated by the processor based on a series of measurements.

The measurement accuracy is ±0.5 mm, which is comparable to the magnitude of a low-frequency light wave. They have low power, the measurement range does not exceed 1 km. The devices are quite cheap. The main direction is application in household devices.
