For this reason, estimating the mechanical and chemical deterioration of works of art has been a continuous procedure performed in museums. The developed prototype combines two optical techniques (Fringe Projection and Hyperspectral Imaging in the Visible and SWIR) in one system, enabling the acquisition of the colorimetric, morphologic, chemical and spectroscopic information from the artwork. This combination of: non-destructive techniques; specialized calibration; the use of material, substance, component and pigment databases; data fusion and classification methods, allows the characterization and analysis of canvas and panel paintings. Furthermore, the prototype is portable to allow on-site measurements and analysis. The performance of the prototype is presented from both hardware and software development. Results obtained from real case studies show that mechanical and chemical deterioration can be characterized in complex surfaces.

The device combines two complementary optical techniques, hyperspectral imaging in the visible (400-1000nm) and infrared (1000-2500nm) using electronically tunable optical filters, and 3D scanning using structured light projection. These techniques are integrated in a single prototype allowing the recording of hyperspectral and shape streams, software data fusion and automated estimation of artwork deterioration and degradation using signal processing. The prototype is portable and user-friendly and has been used to study artwork of the baroque period at partner museums in the consortium, IPCHS, Slovenia and RABSAF, Spain. The main challenges posed in the development of such a device were: (i) the integration of reliable and robust illumination units, both for the hyperspectral and 3D channels, which meet the desired requirements o...

The core of the system is a ring resonator-based integrated optical beam forming network chip. Its principles are explained and demonstrated by presenting some measurement results. The system architecture around the chip is based on a combination of frequency down conversion, filter-based optical single sideband modulation

The main challenges posed in the development of such a device were: (i) the integration of reliable and robust illumination units, both for the hyperspectral and 3D channels, which meet the desired requirements of power, homogeneity and stability, (ii) the merging of hyperspectral and 3D data streams in order to construct rich digital representations of the work of art, and (iii) the development of classification strategies based on eigenvector analysis and point cloud segmentation for mechanical alteration and supervised classification by considering spectral samples for the identification and quantification of chemical deterioration.
