The LaserSweep system is a portable laser scanning device that: 1. Uses a rugged PDA with built-in software to perform cable-free measurements on rail infrastructure like tunnels, bridges, and platforms. 2. Can capture full profiles, partial profiles, and single points to efficiently measure structures and ensure vehicle clearances. 3. Exports data directly to Balfour Beatty Rail's ClearRoute software for analysis and is approved for use on UK rail networks.
