چکیده
Non-destructive testing (NDT) is a broad group of and analysis techniques used in science industry to evaluate the properties material, structure, or system for characteristic defects discontinuities without causing damage. Recently, infrared thermography one most promising technologies as it can inspect large area quickly using non-contact non-destructive method. Moreover, has proved be valuable approach evaluation structural stability materials. Pulsed active that utilizes external energy heating. However, due non-uniform heating, lateral heat diffusion, environmental noise, limited parameters thermal imaging system, there are some difficulties detecting characterizing defects. In order improve this limitation, various signal processing have been developed through many previous studies. This review presents latest advances exhaustive summary representative pulsed according physical principles excitation sources. First, basic concept introduced. Next, principle conventional reviewed. Then, we recent each processing. Finally, research trends

متن کاملImage Processing for Automated Flaw Detection in Pulsed Thermography
Infrared (IR) thermography has evolved in recent years from being an emerging nondestructive testing (NDT) technique to a viable approach for both aerospace manufacturing and in-service inspections. One of the drawbacks of thermography techniques is that no standard signal processing has been universally adopted and that different algorithms yield different sizing results. Additionally, the dat...

Rapid progress is being made in our ability to modify the aging process. Rather than serving as a period of debility and decreasing health, for many people, the later years of life are becoming a period of continued productivity, independence and good health. Progress is also being made in increasing average lifespan. The leading causes of death (cardiovascular disease, cancer, lung disease, di...
