“…Shearography can be combined in a single equipment with digital speckle photography to obtain full characterization of surface strain [20] or included in a multi-functional sensor, capable to work on panel paintings and canvas [21]. The integration of different techniques, often in a portable equipment, was proposed by different research groups in last years [22][23][24][25] to alleviate the drawbacks of a single diagnostic method. Finally, a very recent trend is the application of OCT (Optical Coherent Tomography), an interferometric technique developed mainly for in vivo imaging of biological tissues, to the examination of paintings.…”

“…As a consequence of moistening of the wood, infestation by wood-destroying fungi and/or wood-destroying insects can occur. The implementation of integrated pest management (IPM) [24,25], which has long been known from agriculture, forestry, and inventory management, only just began a few years ago in the case of wood-destroying organisms in a systematic manner [10]. Monitoring [2,[26][27][28][29], which comprises determination of the causative agent, type of damage and extent of damage, normally results in infestation mapping.…”

The financial contribution of COST Action IE0601 and of University of Florence for covering the publication costs of this volume are gratefully ackwnoledged Main objectives and resultsThe main objectives of the Workshop, which have been achieved at a quite satisfactory level, can be summarized as follows:a) To present a "state of the art" about selected subjects dealt with by the Action (From the program: "Historic wood -structure and properties", "Wood material -ageing and non-biological degradation", "Assessment & Diagnosis", "Diagnosing the surface of painted wood" "Diagnosing the efficiency of object treatments", "Contributions from Wood Science to conservation issues", "Expressing needs in the field of conservation, of objects and/or monuments, in matter of Wood Science"); b) To improve mutual knowledge and acquaintance between MC Members, and WG members; c) To present current ongoing research, and inform specialists of different fields, all working towards conservation of WCHOs (Wooden Objects belonging to the Cultural Heritage), about the work of their colleagues and the scientific work being carried out in different Institutions; d) To provide an opportunity for discussing interdisciplinary subjects, which are very important for study and conservation of WCHOs; e) To identify the main subjects to be discussed in forthcoming activities.In fact this Workshop was instrumental for defining and addressing the future activities of the Action; a very good atmosphere, full of enthusiasm and of availability towards cooperation, emerged, and has been maintained during successive activities. The previous meeting (in Tervuren) and this one were both organized at short notice, as is normally the case at the beginning of an Action. They allowed interactions between scientists who often met for the first time and exchanges of general information from subjects of other fields. In the plenary meetings which followed, scientific contributions on well-focused subjects have been made possible by the longer time allowed for submission of papers. In this occasion several topics were also suggested for future general or focused meetings. Allocating and refereeing the PapersFor this Workshop, the Steering Committee (see Annex 2) fulfilled the role of Scientific Committee, preparing and managing its scientific aspects, and organising the refereeing process of the submitted papers, all of which have been peer-reviewed for this publication. Emphasis should be given to the fact that all accepted paper were deemed of high scientific calibre and deserved the same "dignity", no matter whether they were allocated as Oral presentations or Posters, such allocation being dictated by inescapable time constraints. Unfortunately some Authors were not able to submit their paper for publication; the titles of their presentations can be found in the Programme (Appendix 2). In some cases, the screen presentations they offered can be found on the Action's website . Others, not being of English mother tongue, submitted...

“…An integrated multidisciplinary approach is now currently accepted in preservation Hinsch et al, 2007;Tornari et al, 2007) as the drawbacks of a single diagnostic technique can be partially overcome by integration and because of complementariness. In the particular case of panel painting diagnostics, pulsed thermography offers the possibility of integration to holographic interferometry testing, providing complementary information on defects depth as previous studies have suggested (Schirripa Spagnolo et al, 2000;Grinzato et al, 2000;Grinzato et al, 2002;Ibarra-Castanedo et al, 2008).…”

Holographic and thermographic techniques have been recently applied in artwork diagnostics for the quantitative evaluation of defect size and depth in laboratory samples of artworks. The aim of this study is a comparison between holographic interferometry (both double exposure and real time), and pulsed thermography (PT) processing techniques such as differential absolute contrast (DAC) and pulsed phase thermography (PPT) for the detection of the subsurface flaws on wooden panel paintings. The performance of holographic techniques can be reserved for investigation of particular defects (cracks, detachments) at incipient stages, where high resolution/sensitivity is required, while PT can provide interesting quantitative results in situ.KEY WORDS: Holographic interferometry, pulsed thermography, artworks, pulsed phase thermography, differential absolute contrast.

“…A comprehensive description of interferometric optical methods in cultural heritage is given in a recent book [11]. Recent developments have focussed on solving the specific problems associated with studying artwork [12]. This is the topic of this paper: the implementation and characterisation of shearography for cultural heritage applications.…”

Shearography as part of a multi-functional sensor for the detection of signature features in movable cultural heritaged

et al. 2007

This is one of a series of papers submitted by the Multi-Encode Project consortium (006427 (SSPI)). Shearography, a full-field speckle interferometry technique, is applied to the investigation of movable cultural heritage. For this project a portable shearography sensor was developed, with conventional sensor hardware supported by novel algorithms and instrument control software. The sensor has been used for an extensive measurement program, the purpose of which is to develop an Impact Assessment Procedure; this is to determine the capabilities of a shearography sensor in this measurement application. Data from the sensor, which shows the location of defects in the artwork, is stored in a database for future analysis and comparison. The particular advantages identified for incorporating shearography in a multi-functional sensor are the ability to measure unstable objects, such as gently vibrating canvas paintings, adjustable interferometric sensitivity and a different sensitivity parameter (displacement gradient) to the other sensors investigated. This work will assist in fulfilling the aims of the project, the detection of signature features for security purposes and the study of changes in artwork for conservation purposes.
