Paper Abstract

Due to the increasing air pollution in recent years, many valuable historical monuments of stone are falling into disrepair. The need arises to study the mechanisms of stone decay in detail. An instrument is described, which should detect damages before they become visible and help, on the other hand, to gain insight into the underlying processes. The technique used is Electronic Speckle Pattern Interferometry (ESPI). First measurements of microscopic wall deformations in a church over a time period of 3 weeks are presented.
