Paper Abstract

A miniaturized electronic speckle pattern interferometry system (ESPI) has been developed for in situ measurements of microdeformations on buildings and monuments. Direct coupling between object and the compact optical head of the system enabled detection of microdisplacements even in non laboratory environments. Several examples of applications in deterioration investigations are presented.
