Indian Make Portable and Real-Time Shearography System (IMPRESS) for Non-destructive Testing (NDT)

Part of the Lecture Notes in Mechanical Engineering book series (LNME)

Abstract

Laser shearographic interferometry is a well-proven NDT technique for detecting defects in various structures and mechanical components. There is only a countable number of shearography systems available commercially. This paper highlights the development of an indigenous low-cost digital laser shearography system, namely, IMPRESS (Indian Make Portable and Real-time Shearography System). Herein, the details of the system are explained with its online and in situ capability. Moreover, a few specimen-level results are shown to demonstrate the application of the system. The developmental cost of this system is much lower as compared to commercial systems. Therefore, it would be beneficial for small and medium-scale Indian industries that are desirous of using shearography as an NDT tool in their production line. Currently, the system is being upgraded to make it on par with other commercial systems.
