Abstract: A system for inspection of a blade of a wind turbine in operation is provided. The system comprises a light projection unit, an imaging unit and a processing unit. The light projection unit generates and projects a light pattern towards a blade of a wind turbine in operation. The imaging unit captures a plurality of scanning light patterns on the blade of the wind turbine during rotation of the blade. The processing unit is configured to process the plurality of the captured d light patterns from the imaging unit for inspection of deflection of the blade. A method for inspection of a blade of a wind turbine in operation is also presented.
