QUALITY ASSURANCE TESTING FOR ROTOR BLADES OF A WIND ENERGY INSTALLATION

摘要

The apparatus has a point laser (4) for emitting laser light (5). A set of photodiodes (6) is arranged outside a light path of the light for detection of the light. The laser light is partially reflected from a surface (7) of a rotor blade (1) and hits the photodiodes. The photodiodes are arranged at the surface according to the reflection on the surface at an angle of approximately 45 degrees to receive the reflected laser light. The photodiodes determine a location at which the reflected light arrives to resolve positional changes in a plane formed by the laser light and the reflected light. An independent claim is also included for a method for checking manufacturing quality for a rotor blade of a wind energy plant.
