# Lidar Acquisition Settings

The acquisition tab of lidar settings displays each lidar session in the **Sessions** window. A session is a lidar record associated with a file (.rxp or .ldr) and with associated lidar parameters. In other words, whenever you start and stop the lidar, you create a session. The lidar sensor configuration parameters used to record each session are displayed in the acquisition tab. 

Individual sessions can be disabled by unchecking the session within the **Sessions** window. If disabled, the session will not be fused when building a pointcloud.
