摘要：The invention relates to a method for testing a rotor blade (13.1) of a wind power plant (1), which sweeps across a rotor blade surface to be covered during operation of the wind power plant, comprising the following steps: emitting a target light beam (20), in particular a target light beam having a power density, in a direction of the target light beam onto the rotor blade surface to be covered; detecting a possible reflection of the target light beam by a detection device at a point of incidence (16) on the rotor blade; electrically controlled emission of a measurement laser beam (21) which has a power density that is larger than the power density of the target light beam immediately after detection of the reflection at the point of incidence so that the rotor blade is heated at the point of incidence; measuring a temperature distribution at the point of incidence; and repeating the steps (a) to (d) for several points of incidence.
