Optical coherence tomography for varnish ablation monitoring
SPIE Digital Library (Jul 16 2007) Non-Medical Explore Article
Optical Coherence Tomography (OCT) is a new, fast-growing technique for non-contact and non-destructive imaging of semi-transparent objects. It has been recently used for diverse applications in art conservation subject - among others it is very well suited for varnish layer imaging and thus for monitoring of varnish removing process, including the laser ablation. In this study we show how to use the OCT technique to obtain the information required for ... (Read Full Article)

Preliminary results of the application of optical coherence tomography (OCT), in particular in its spectral mode (SOCT), to tracking of deformations in paintings on canvas caused by periodical humidity changes are presented. The setup is able to monitor the position of a chosen point at the surface of a painting with micrometre precision, simultaneously in three dimensions, every 100 seconds. This allows recording of deformations associated with crack formation. For ...
