Popis: In the field of art conservation there is an increased demand for non destructive and non invasive techniques able to perform remote defect detection for structural evaluation of historical structures and works of art. The techniques must have some basic important characteristics as non destructivity, accuracy, repeatability and desired features as non contact, portability, resolution, broad range of applicability. The simulated infrared thermography (SIRT) and digital holographic speckle pattern interferometry (DHSPI) are systems discussed in detail elsewhere; in this paper have been used in combined testing on art related targets according to the above criteria. Results confirm the effectiveness of both techniques in the conservation field and examples are here in presented. Each system is thus described as individual method highlighting the advantages and limitations of each. The aim is to present the suitability and appropriateness for accurate defect mapping in structural documentation reports. This work is considered preliminary and is in progress for the future hybrid synthesis of systems and data.
