Description

Nondestructive evaluation (NDE) technique appeared as the natural consequence of materials analysis by using a variety of physical fields and particles which being propagated through the specimen are able to produce the image of its inner structure. Disadvantage of traditional “shadow” or “backscattered” images is that the “weak” details are scarcely seen on the background of “stronger” ones. This is why the introduction of the tomographic principles, allowing to “slice” the solid into individual layers, was viewed as a revolution in vision techniques (especially in X-ray imaging). Ultrasonic, ultra-high frequency and nuclear magnetic resonance tomography are under quick development now.

Dynamic Thermal Tomography: New Nde Technique to Reconstruct Inner Solids Structure Using Multiple IR Image Processing

Brunswick, ME

Nondestructive evaluation (NDE) technique appeared as the natural consequence of materials analysis by using a variety of physical fields and particles which being propagated through the specimen are able to produce the image of its inner structure. Disadvantage of traditional “shadow” or “backscattered” images is that the “weak” details are scarcely seen on the background of “stronger” ones.
