Cavity Autoscanning Laser System (C-ALS) from MDL Laser System

MDL's C-ALS cavity monitoring system is a self-navigating, 'motorised' robotic probe designed to enter & survey dry abandoned mine workings or cavities. With a diameter of just 50mm, the unit can be deployed down pre-drilled boreholes of 65mm or more, from where it employs a miniaturised laser scanner to measure the three-dimensional shape of the void together with its surface reflectivity.

The C-ALS, cavity monitoring system may be deployed down hole to a depth of 300m, up hole or horizontally to a distance of 100m.
