The device is developed for measuring the deformation of natural and artificial underground spaces, especially active mines. The deformations are derived from LIDAR distance measurements of network of reference points. Each reference point consists of steel rod embedded into wall and stainless steel ball as reflector. The LIDAR is placed in a precision adjustable 2-axis mount and which can be fitted to any reference point. The system is portable, battery powered. Part of the system is software allowing reading and processing LIDAR measurement data. The measurement is usually started immediately after excavation, and then go on as long-term monitoring after the completion of the construction or mining activities
