Measuring wind turbines remotely using laser

 The rotor and mast of a wind turbine can oscillate even in normal operation. The analysis of these oscillations plays an important role when the equipment is being developed and maintained. Up to now, this analysis has only been possible at discrete points located directly on equipment. Researchers at the Fraunhofer Institute in Germany use modern information technology to remotely measure the oscillatory pattern over the entire structure of the facility from several hundred meters away.
