A stress-strain method for tuning a holographic nondestructive testing system
Abstract
The GC Optronics Mobile System was designed to inspect sandwich-type building panels using holography. The developer properly set the system for the inspection of a particular panel and the system gave good results. However, the evaluators discovered that when a panel of different characteristics was inspected, the system needed adjustment. It was also found that finding the new proper setting was no easy task. This project was then undertaken in an attempt to simplify the process of adjusting to a new setting.
