System and method for inspecting defects of structure by using x-ray
A method of detecting a defect in a wind turbine blade uses a system that includes an X-ray generator, moved by a first transporting means, that generates X-ray to be irradiated to the wind turbine blade; an X-ray detector, moved by a second transporting means, that detects the X-ray generated by the X-ray generator and transmitted through the wind turbine blade; and a control unit.
