Because artworks are a major part of our culture their preservation is of great importance and therefore they need to be protected from any damage. But the change of environmental conditions like temperature or humidity leads to internal stress, which can result in different defects like delaminations or cracks. The deteriorations occurring due to ageing or transport are often small and invisible, but they can enlarge and produce new irreversible damages. Therefore it is important to detect small changes in the surface as well as deteriorations under the surface. A combination of fringe projection and shearography data is a very suitable method to fulfill this task. While fringe projection is used to determine the surface structure, the shearography gives information about the strain occurring due to loading, which allows conclusions about weaknesses in the internal structure. We optimized both techniques for the use in the preservation of artwork and combined the resulting data by a mapping process. In this paper we present the advantages and also the limits, which need to overcome.

“…In recent years, it has been combined with phase shift techniques [6][7][8][9][10][11][12] or Fourier transform methods [13][14][15][16][17][18]. With some exceptions [19,20], reports from work with these methods are done inside the optical laboratory. Recently, the authors in [21] have developed an optical measurement system to measure surface profile and three-dimensional deformation of small objects simultaneously, by a combination of fringe projection and a two-dimensional digital image correlation technique.…”

Fringe projection is a versatile method for mapping the surface topography. In this paper, it is used to measure the deformation of steel plates under static penetration. Here, the surface shape changes continuously. Therefore, it is important to minimize the registration time. To achieve this, we apply a method of fringe location with subpixel accuracy that requires only a single exposure for each registration. This is in contrast to phase shifting techniques that require at least three separate exposures.
