What is a non-intrusive inspection?

A non-intrusive inspection (NII) is a method used to examine the integrity and condition of structures, materials, or systems without causing any damage or disruption to them. Commonly employed in security, engineering, and environmental assessments, NII techniques include technologies like X-ray imaging, ultrasonic testing, and thermal imaging. These methods allow for the detection of flaws or irregularities while preserving the original state of the inspected object. NII is particularly valuable in scenariOS where access is limited or where maintaining the object's usability is essential.
