Résumé
Introduction In the fields of cultural heritage, archaeology, art history and museology,many examination methods are based on imaging techniques. To date, numerous different imaging approaches exist, and although most of them have already existed for several decades, recent advantages in hard- and software technology make their application more straightforward than ever. In this chapter, an elementary but essential coverage of photodetectors, illumination equipment and signal composition will be provided to better understand the basic principles of common non-destructive scientific visualisations such as broadband colour photography, non-visible ultravioletand infrared imaging, fluorescent photography, spectral imaging and X-ray radiography. Although important, many means to characterise and depict archaeological and heritage object will not be discussed (such as particle induced X-ray emission or PIXE, ultrasound techniques, thermography,stereomicroscopy, computed tomography, neutron imaging), nor will the file formats needed to store these visualisations and many other related archiving issues. For those interested in these topics, the following chapters of this book and the excellent compendium of MacDonald are recommended. Although several practical examples will illustrate each and every visualisation technique tackled in this chapter, it is still necessary to go back to some basic physics. Since imaging art objects and archaeological artefacts are all based upon some essential principles of how matter interacts with radiant energy, this chapter will start with a concise exploration of the world of matter, charge and energy.
