Abstract: A method for the determination of the deflection of a wind turbine blade is provided. A distance between at least one root location towards a root end of the wind turbine blade and at least one tip location towards a tip end of the wind turbine blade is measured. A blade deflection profile is then calculated based on the measured distance between the root and tip locations and a known modal profile of the wind turbine blade.
