The performing of nondestructive tests through ultrasound finds a broad range in the industry, as well as in the field of academic research. There is a great demand for detection and assessment of structural flaws in pipes, bridges and other structures made of several types of materials. In a controlled environment, you may want to determine physical properties of a specimen such as its thickness. The utilization of ultrasound fits well in these scenarios. On top of that, the use of noninvasive methods as the one described here has a great advantage compared to techniques that involve the change of the material’s structure. The present work aims at implementing an 8-Channel Ultrasound Platform dedicated to academic research through the use of development kits. The platform comprises a transmit-side and receive-side signal path. The raw data acquired simultaneously from the eight channels are saved in a binary file for post-processing. Therefore, parameters such as amplitude, frequency and pulse length can be extracted and manipulated to one’s desire. The software MATLAB was used to carry out the analysis of the acquired data and display results. This would not be possible with a proprietary ultrasound platform. Unfortunately, it is the most commonly found type of ultrasound system in the market. This fact restricts the research in the academic field. Hence, this work is focused on expanding the research in nondestructive testing through an open platform, as well as inspiring future works in the R&D scope. |
