Laser Speckle Imaging
Monitoring dynamic processes in oil paint, paper and metal
Oil paint, paper and metal can undergo changes by cleaning and outside influences. Fluctuations in temperature and relative humidity can lead to brittleness, cracking and the formation of undesired degradation products.
About the project
By using Laser Speckle Imaging (LSI) it is possible to monitor dynamic processes in oil paint, paper and metal. LSI measures minute changes in the scattering of lasers, a signal that is processed into quantitative information linked to time and location about movements inside the object. This makes it possible to measure the penetration of solvents in oil paint and paper, and hopefully also to detect active formation of cracks in metal objects. This information enables us to substantiate conservation practices scientifically and aids preventive conservation by early detection of changes in materials.
