Non Destructive Techniques

Cultural heritage is a valuable and characteristic symbol of every country. It should be handled with care and it must be exhaustively investigated and measured with non-destructive techniques. In this chapter, we will talk about different reflectance measurement techniques to obtain the conservation state of the artwork. With this reflectance characterization, conservators, and curators could soon determine the best maintenance procedures for restoration purposes. Also, a new technique for lighting will be discussed, where the artwork can be also photonically restored illuminating with the correct light in the desired area of the artwork using a spectrally selective projection system.

A New Technique

This paper describes a new technique called “Holo-moire´ interferometry” which combines the moire´ and holographic techniques so that full-field measurement of the displacements normal to the line of sight is achieved. The method is particularly useful in measuring in-plane displacements; a type of measurement for which the conventional moire´ technique is too insensitive, and for which holographic interferometry requires pointwise separation of displacement components from a multiple-hologram scheme. Holo-moire´ interferometry overcomes the major limitations of both. An example which compares experimental with analytical predictions is presented. The limitations of the scheme are discussed.
