| Resumo: | English: In this master's thesis an experimental method is developed to measure diffusivity and, in the future, detect cracks with a moving laser spot, which can scan the surface of the sample and probe different regions, with the aim of obtaining experimental results of diffusivity measurements in different materials. For this purpose, the flying spot method, which is a non- destructive test, has been used. To understand how the experiment was carried out, thermography in general is first discussed and then focus on the flying spot method. After that, there is a theoretical section specific to this method to demonstrate where the equations used to calculate the diffusivity value come from. There is also a description of the equipment used, as well as its operation and limitations. Then, the results obtained are presented and discussed and the work concludes with a summary and future work in this. |
