Laser Line: The fan-shaped form of the laser line inevitably results in parallel shadowing at vertical edges.

In order to make these areas visible, only changing the sensor of the object position helps.

As a general rule, measuring objects with steep edges cannot be one hundred percent measured using laser

triangulation. The missing areas can only be supplemented or interpolated using suitable software.
