AbstractThis paper presented a three dimensional deformation and full-field temperature measurement method for continuous wave laser irradiated structures over a range extending from the room temperature to the melting point. The deformation was measured by the three dimensional digital image correlation technique. The speckle pattern was made on the specimen surface by the high temperature glue with a maximum service temperature of 1700 degrees C. A bandpass filter and a blue light source were used to eliminate the effect of thermal radiation from the laser irradiated region. The accuracy of present method was validated by the coordinate measurement machine and the laser Doppler vibrometer. According to the relationship between the gray value of images and the temperature, the full-field temperature distribution were measured by the colorimetry temperature measurement method. Finally, parameters that affect the response of laser irradiated thin plates, including laser power, high-speed airflow, plate thickness and material properties are investigated.
