What are the main components of a lidar system?

The main components of a lidar system include the laser source, receiver, scanner, and GPS unit.

The laser source is fundamental to lidar technology as it emits laser pulses that will bounce off objects and return to the system, enabling distance measurements. The receiver captures the reflected laser light, processing the information to determine the distance to the target object based on the time it takes for the light to return.

The scanner is responsible for directing the laser beam over the area being surveyed. This component allows the system to map large areas systematically by sweeping or rotating to collect 3D data points.

Lastly, the GPS unit is essential for positioning and georeferencing the lidar data. It provides location information, ensuring that the collected data corresponds accurately to geographic coordinates. This combination of components enables lidar systems to create detailed, accurate surveys and models of the scanned environment, making it a powerful tool in various applications, such as topography, forestry, and urban planning.
