Title (EN) LASER ULTRASONIC THERMOGRAPHY INSPECTION
(FR) INSPECTION PAR THERMOGRAPHIE ULTRASONORE À LASER
Abstract:
(EN) A non-destructive method for the condition assessment of a turbine component is provided. A pulsed laser is used to excite a desired surface of the turbine component by directing the pulsed laser at the desired surface to couple ultrasonic energy into the surface of the turbine component. A thermographic image of the desired surface under the influence of the ultrasonic is captured by an image receiver. A system for the non-destructive detection of defects in a material utilizing acoustic thermography is also provided. The system includes a pulsed laser to couple ultrasonic energy into the material, an infrared camera to capture the thermographic image, and a processor communicatively coupled to the infrared camera to receive, store, and analyze the thermographic image.
(FR) La présente invention concerne un procédé non destructif d'évaluation de l'état d'un composant de turbine. Un laser pulsé est utilisé pour exciter une surface souhaitée du composant de turbine en dirigeant le laser pulsé au niveau de la surface souhaitée pour coupler l'énergie ultrasonore dans la surface du composant de turbine. Une image thermographique de la surface souhaitée sous l'influence des ultrasons est capturée par un récepteur d'image. L'invention concerne en outre un système pour la détection non destructive de défauts dans un matériau au moyen de la thermographie acoustique. Le système comprend un laser pulsé pour coupler une énergie ultrasonore dans le matériau, une caméra infrarouge pour capturer l'image thermographique, et un processeur couplé en communication à la caméra infrarouge pour recevoir, stocker et analyser l'image thermographique.
