Abstract:
A scanning LIMM system has been developed that can spatially map the piezoelectric/pyroelectric activity of piezoelectric materials. This has been successfully used to image a number of different commonly found defects in thin PZT samples. The present system can be used as an R&D tool, but with further developments to increase speed and usability the technique could be extended to use in a QA environment.
