Abstract :
In order to avoid over-cleaning during laser assisted restoration of artworks, several techniques have been developed. In contrast to approved laser induced breakdown spectroscopy using ICCD detectors, sensitivity and lambda-resolution is much less. However, it was found out that for monitoring during laser cleaning the complete (low resolution) spectrum may be used as an individual "fingerprint" of the layer just being laser irradiated
