LE PROFILOMETRE SBS: UNE MESURE FACILE DES PROFILS DES TUNNELS

The device, designed by the author and built by an electronics firm, quickly plots, by means of a laser beam and a rotary mirror system, the cross-section of a tunnel in relation to a reference point linked to the track or to the vertical. This lightweight, easily employed apparatus is also useful for measuring the position of obstacles in relation to the clearance gauge.
