Abstract

Cultural Heritage (CH) is concerned with objects and materials that witness the historical evolution and human civilisation and are due to be inherited to next generations. As such prevention of damage and failure is an ultimate never-ending aim in art conservation science if CH protection is concerned . Interferometry techniques offer the spatial sensitivity to assess minor changes prior to damage while important ethic principles of non destructivity, non contact and non invasive type of measurements are satisfied as basic requirements for art object examination. Visual qualitative evaluation of the state of condition as provided by interference patterns as well as the quantitative surface morphology of deformation are important information sources for the conservation documentation acting as tools in the hands of the conservator. Hence it is herein briefly described how our optical laboratory explore the trends in modern interferometric instrumentation to adjust it to the needs for documentation in Cultural heritage field. In this context the development of a portable interferometry system based on the fundamentals of holographic and speckle interferometry satisfying the limitations and over passing the state of the art in on-field measurements for structural diagnosis in CH is presented and some examples from movable and immovable artwork examination is given.
