Which component allows a lidar system to emit laser pulses?

The component that enables a lidar system to emit laser pulses is the laser source. This part is crucial for the operation of lidar technology, as it generates the laser beam that is directed toward the target area to gather distance and other relevant data.

When the laser pulses hit an object, they reflect back to the system, allowing it to calculate distances based on the time it takes for the light to travel to the object and back. This precise timing is fundamental to the functionality of lidar, as it relies on the speed of light to measure distances accurately.

Other components, while essential to the overall functionality of the lidar system, do not emit the laser pulses. The lidar receiver collects the reflected signals, the signal processor interprets and analyzes the data received, and the thermal sensor typically monitors temperature changes but does not play a role in pulse emission. Therefore, the laser source is the key component responsible for emitting the laser pulses in a lidar system.
