    • PURPOSE: A system for monitoring the deflection of a blade for a wind turbine is provided to measure a displacement between the blade and a wind tower or to measure the deformation of the blade through a laser displacement sensor part inside the tower, thereby diagnosing the deflection of the blade in real time. CONSTITUTION: A system for monitoring the deflection of a blade for a wind turbine includes a laser displacement sensor part (110) and a data processing part (130). The sensor part inside a wind tower irradiates a laser beam forwards, receives a light which is the laser beam being reflected and returned from a blade, and obtains a displacement signal between the blade and a tower. The data processing part receives the signal from the laser displacement sensor part, and processes the signal into data.
