India is pursuing research and development in various aspects of NDT including in service inspection in fields such as ultrasonic testing, acoustic emission testing, single and multi-frequency eddy current testing, signal analysis, X-ray diffraction, high resolution X-radiography, radiographic image enhancement, laser holography, laser speckle scattering, laser based ultrasonic generation, electromagnetic acoustic transducers, artificial intelligence approaches, and intelligent processing of materials. The emphasis is not only on the methodologies of acquisition of the data but also on the means to analyze them properly so that complete characterization of the type, nature, and size of the defects can be made, as well as their effects on the structural integrity of the components. The approach is comprehensive, the means being total awareness, and the objective is a complete quantitative characterization of defects and other required physical parameters, leading to defect free and safe components and systems.
