Nondestructive testing is a wide group of analysis techniques used to evaluate properties of components, systems and materials without altering the original properties. These testing technologies are gaining popularity due to its time and cost saving benefits over other material testing technologies. NDT testing methods include ultrasonic, remote visual inspection (RVI), liquid penetrant, magnetic-particle, eddy-current testing, low coherence interferometry and radiographics. NDT is comprehensively used in mechanical, forensic, electrical, systems, civil, and aeronautical engineering as well as art and medicine.
