In recent years, a new sensor called Lidar Continuous Wave has been introduced into the commercial laser scanners family. The main advantage of this new type of sensors is the complete recording of the return pulse after the collision with various ground features along the path of the laser pulse to the surface of the ground. With full wave recording, the output of the cloud of points has a higher density and more reliability, along with new parameters, including pulse widths and pulse amplitudes for each point. These new parameters help us analyze and investigate outcomes of the three-dimensional cloud of points of these types of sensors ever more correct and comprehensive . Lidar's output can be applied in various fields, including updating 3D databases, extracting ground features, providing a 3D model of buildings, providing forest models, urban management and planning, traffic management, air pollution control, tourism industry, crisis management, and many other applications. In this article, we first discuss some points about the Lidar Continuous Wave sensor, the signal processing carried out on it so far, and how to extract the three-dimensional points from it. Examining different types of these sensors and a brief history of their evolutionary process forms the next section. In the end, various applications of this data in forest, urban and hydrographic fields are discussed.
