Abstract

The possibility of employing a digital speckle pattern interferometer with optical fibres for non-destructive testing of artworks was evaluated. A simple and accurate fibre optic interferometer, able to perform real-time measurements in a hostile environment, was realised with a minimum of optical components and a minimum of adjustments. As a result, the deformation map of wooden panel painting or mural frescos under thermal stresses may be depicted. Experimental results obtained by the application of this interferometer both on laboratory models and on a mural fresco are presented.
