The difference between radar and laser radar is evident in the following aspects: Principle of operation and signal carrier Traditional radars use radio waves (electromagnetic waves in the microwave range), emitting electromagnetic signals, receiving echo signals reflected from the target, and calculating the position and speed of the target using time difference, Doppler shift, etc. Laser radar uses a laser beam (visible light or infrared light), emitting narrow laser pulses, and calculates the distance using precise time measurement, as well as using a scanning mechanism to generate a three-dimensional point cloud, providing detailed information about the shape and distance to the target.

How does a laser sensor work? The principle of operation of a laser radar includes the following main stages:

Emission of laser pulses:

A laser radar emits a series of laser pulses in the direction of the target area using a laser emitter.
These laser pulses propagate through the air and serve as the basis for detecting the surrounding environment.
Propagation and reflection of pulses:

When a laser pulse encounters an object, it is reflected.
The reflected laser pulse carries information about the target object.
