Qualitative diagnostics of wind-turbine blades inspection using active thermography

Paper presents production-ready system designed for non-destructive inspection of wind-turbine blades. System is based on active thermography method with pulsed excitation. Designed and implemented by author's solution, software and image processing techniques allow implementing the system as an end line manufacturing quality control. Authors present new approach to calibrate geometrical distortion of thermal cameras with using Peltier unit matrix. Results of assessments carried out on a portion of a wind turbine blade are presented in the last part of this article.
