Abstract

We report a new 1.5 µm laser vibrometry system (based on a precise image tracker) that measures vibrations of rotating blades of wind turbines at ranges up to several hundred metres. After successful tests with a wind turbine scale model, measurements on real wind turbines were recently made and first results will be presented.
