Fraunhofer IPM develops optical systems for the detection of contact wire wear, contact wire position, clearance profile, position of poles, rail profile, and train geometry. High resolution laser scanners combined with fast image processing provide the necessary measurement data, which is the basis for planning specific maintenance work. The sensors record the measurement data at travel speeds of 100 kilometers per hour and more – quickly, precisely and reliably. Fraunhofer IPM measuring systems are used worldwide to monitor the condition of railway networks.

3D Clearance Profile
Our laser scanners measure up to 554 profiles per second without contact. This way, objects in the track environment of only a few centimeters in size can be detected even at high travelling speeds.
