铁轨外轮廓检测对于铁路运行安全至关重要。采用激光轮廓扫描仪的好处是无接触，精准以及快速。为了得到铁轨整体外轮廓，需要两支轮廓扫描仪同时工作。每一个测量小车配有四个同步以后的测量系统。测量可以在时速100公里/小时的运行速度下进行。计算机可以实时对比测量结果，如果发现超过之前设定的公差范围，则会警告铁轨处于不安全状态。

The measurement occurs without contact and it is very accurate and fast. To be able to acquire the whole profile of the rail head two LLT sensors are required. Per inspection car four systems are employed which are synchronized to each other. The measurements take place at speeds of up to 100 km/h. In the measurement computer an ideal profile is saved which is continually compared to the measured profile. If the preset tolerances are exceeded, the rail is classed as unsafe and marked in the PC
