With the rapid development of science and technology in China today, nondestructive testing (NDT) has also made dramatic progress. The intelligence of testing process and foolproof of operation process is the most immediate embodiment of this progress, while most of the time such progress needs to be supported by LabVIEW and other software platforms virtual instrument. For this end, in this article, the author conducts a specific study on the application of LABVIEW-based virtual instrument technology in NDT, in the hope that this study could bring inspiration to relevant practitioners.

The EU imposes standards for the use of wood in structural applications. Local singularities such as knots affect the wood mechanical properties. They can be revealed by looking at the wood fiber orientation. For this reason, many methods were proposed to estimate the orientation of wood fiber using optical means, X-rays, or scattering measurement techniques. In this paper, an approach to assess the wood fiber orientation based on thermal ellipsometry is developed. The wood part is punctually heated with a Nd-YAG Laser and the thermal response is acquired by an infrared camera. The thermal response is elliptical due to the propagation of the heat through and along the wood fibers. An experiment is presented to show the capacity of such techniques to assess fiber orientation on wood specimen. In addition, an appropriate algorithm is given to extract the orientation of the ellipse.

“…SFH is traditionally used in the case of high conductive materials (metals for example). [5][6][7] In this paper we are interested by glass material which presents low thermal conductivity, specular reflection and transparency. The experiments have been done using a broken glass material sample (Figure 1 In this paper, the goal is to minimize the processing time for a correct accuracy.…”

Thermal imaging is nowadays widely used in many industrial areas for non destructive analysis. This paper focuses on the detection by active thermography of cracks in a transparent and specular piece of glass. A continuous laser scans the target by creating a hot spot that is acquired by a thermal camera. A thermal map is computed by averaging of thermal measurements for all the positions of the hot spot on the target. Then edge filters are applied to highlight the cracks. Experimental results demonstrate the validity of the material damage estimation in a short processing time.
